Decades ago, every cyberbanking accessory was closed with one of two types of screws: a minus-shaped Flat/Slot head, or a plus-shaped Phillips head. There was no abstraction — at least, for accepted customer electronics — that boilerplate bodies shouldn’t be able to alleviate their gadgets and booty them apart. And the alone acumen to accept assorted Collapsed or Phillips arch screwdrivers was to handle bigger or abate screws.

Times accept changed, and “security screws” accept become increasingly common. Apple absolutely started application tamper-resistant screws in its Macs years ago, but back it added Pentalobe screws to the iPhone 4, the media took notice, and there was a abrupt accessible blast (actual sample headline: “Apple iPhone 4 Uses ‘Evil,’ Tamper-Proof Screws”). Despite antecedent frustration, however, the band-aid angry out to be simple: buy an inexpensive Pentalobe screwdriver, or alternately, a multi-bit screwdriver with bags of altered bits, like iFixit’s 54-Bit Disciplinarian Kit.
I’ve been application iFixit’s kit for so continued and aloft so abounding great Mac advancement projects that I accede it essential to my office; if a Mac, adamantine drive, or added peripheral needs to be opened, the 54-Bit Disciplinarian Kit about consistently can do it. But back best bodies accept no abstraction what Pentalobe, Torx, Tri-Wing, Hex and added $.25 attending like or are declared to do, I’ve accumulated this guide to explain them all, absorption on the ones acclimated in Apple products. By the time you’re done account this article, you’ll accept a acceptable faculty of the apple of security screws, and the affidavit it’s accessible to keep a kit about to accessible annihilation up…
As Wikipedia explains, a “screw drive” is the allotment of the spiral disciplinarian that absolutely turns the screw, applicable into a canal on the screw’s arch and acceptance torque (turning power) to be activated to abolish the screw. Virtually anybody knows the two best accepted types of spiral drives: the centuries-old, minus-shaped “slot” or collapsed head, and the 80-year-old, plus-shaped Phillips (or added generally, cross-recess) head. But did you know that there are assorted sizes of these heads, as able-bodied as added than 10 altered spiral arch shapes, alignment from stars to squares, triangles, and hexagons?
Below, I list the blazon of spiral drive in bold, as able-bodied as their best accepted sizes. Sizes are adumbrated with numbers, consistently with bigger numbers apery aloft sizes, admitting the acceptation of the numbers can be confusing. Some numbers represent millimeters (1.5, 2.5, 3.5) while others are aloof a arrangement (1, 2, 3), and still others use abstruse sequences (000, 00, 0, 1, 2). The aboriginal spiral drives were historically acclimated mostly by jewelers and watch shops, but as customer electronics accept diminished — and, like the Apple Watch, become added jewelry-like — their screws accept become analogously tiny.

Using iFixit’s spiral drive $.25 is simple: you aloof cull the bit out of the artificial acclimation block it’s in, and pop it into a magnetic hexagonal aperture aloft a 3.75″ metal handle. iFixit additionally includes a about 2″-long metal extender, apparent absorbed here, additional a adjustable 5.5″ extender and 4mm to 1/4″ adapter. If you’ve anytime approved to use a screwdriver in a actual attenuated hole, the amount of the extenders will be instantly apparent; otherwise, the 3.75″ handle will be abundant for best purposes.
The iFixit kit’s 54-piece set includes 9 blocks of 6 bits, which the aggregation says were called for the best frequently acclimated screws in electronics. In my claimed experience, alone a scattering of the $.25 get acclimated over and over again, while others are acclimated for one-off situations; advantageous $30 for the set gets you aggregate in advance, and saves you the $5 or $10 distinct screwdriver amount you would contrarily buy on an as-needed base (and delay about to accept delivered). Note that there are a brace potentially advantageous bits that are conspicuously absent from the set; I’ll highlight the missing ones below.
Five of the six iFixit $.25 apparent above are for Phillips arch screws, one of the two best accepted types of screws in existence. They are shaped like additional symbols, except for a tiny axial appendage advised to reduce the likelihood of stripping (damaging/rendering inaccessible) screws. iFixit’s set includes jeweler-caliber tiny PH000 and PH00 tips, which are ultra-sharp, additional aloft and added accepted PH0, PH1, and PH2 tips; one of these is about all that’s bare to bandy RAM in a Mac. (The set does not include super-small PH0000 or bigger, broadly accessible PH3 and PH4 sizes.) On the far appropriate is a distinct Triangle bit (3mm), which isn’t acclimated for any Apple products, and not to be abashed with the Tri-Wing discussed later. Triangle $.25 are sometimes acclimated in toys.
The abutting accumulating of spiral drives is the Slot or Flatheads, which are apparent aloft in 1mm, 1.3mm, 1.5mm, 2mm, 2.5mm, and 3mm versions. While the 2mm adaptation is acclimated for abounding Mac screws, this accumulating of minus-shaped $.25 can be acclimated to abolish some of the best accepted baby and ample screws in added products; the aboriginal ones can additionally be acclimated to fix some glasses and watches. In a pinch, Flatheads can sometimes be acclimated to extricate a cross/Phillips spiral that has been stripped.

Following the 3.5mm and 4mm Flatheads are a set of JIS (Japanese Industrial Standard) bits, a cross-shaped Phillips arch another acclimated in Japanese-made products. The J000, J00, J0, and J1 $.25 alongside the small- to medium-sized PH000, PH00, PH0 and PH1, but the tip appearance is actual cautiously different. If you see a absolutely baby plus-shaped spiral in your Apple product, it’s added acceptable to be a JIS than a Phillips head.
This is a accumulating of Torx spiral bits, sometimes (confusingly) accepted as brilliant screws or 6lobe screws; their characteristic appearance makes them boxy to abolish unless you accept the appropriate blazon and admeasurement of bit. The aboriginal Torx $.25 attending like six-pointed stars, while the aloft sizes add a annular column to the centermost for aegis reasons. Torx T5, T6 and T8 $.25 can be acclimated to detach abounding Macs.
These Tamper-Resistant Torx (or Torx TR) $.25 anticipate Flatheads from actuality inserted, which would defeat the security. The $.25 labeled T7 through T20 in iFixit’s set are tamper-resistant.
On the appropriate of the Torx T9 to T20 $.25 are two Tri-wing $.25 labelled Y0 and Y1. Unlike the Triangle bit in the aboriginal bit account above, the Tri-wing $.25 accept three blades rather than a ample triangular block, so they attending like Phillips active from assertive angles, but alone fit into Y-shaped screws. Apple conspicuously uses Tri-wing screws to defended the S1 processor central the Apple Watch, but they’re alike abate than the Y0 here; you’ll charge a attention Tri-wing set like this one to get the Apple Watch’s screws out. Aloft Tri-wings accept been activate in assertive MacBooks, as well.

On the appropriate of this set are three Square bits, which attending like their name suggests, and were acclimated added generally a continued time ago; they are not acclimated in Apple products. The Pentalobe $.25 on the larboard of this block are “star” $.25 like the baby six-point Torx stars, but with alone bristles points. Apple conspicuously uses Pentalobe screws in Macs and iPhones, admitting the ones in the iFixit kit are conspicuously Mac-sized; alike the aboriginal (2) adaptation is too ample for the two screws activate on the cheers of all iPhones back the iPhone 4. It’s accessible that the Pentalobe 2 in my set has blah over time, but alike admitting it’s billed by iFixit as right-sized for iPhones, it’s too big for those screws.
To abolish the Pentalobe screws from an iPhone, you’ll charge a P1-sized tip like the Wiha Attention Disciplinarian P1. iFixit has for years recommended that users who abolish those tiny Pentalobes alter them with approved ones instead, affairs a “Liberation Kit” including a P1 disciplinarian and two backup screws. Unless you absolutely plan to accessible and abutting your iPhone with frequency, that’s not necessary, but it’s up to you.
The iFixit set includes six abstracted Hex or Allen bits, starting with the diminutive 0.7mm H0.7 and catastrophe with the 6mm H6.0. While there are abundant standalone Allen/Hex bend sets out there, actual few of them accept the ultra-small H0.7 and H0.9 or baby H1.3 and H1.5 sizes; they about activate with 2mm wrenches and move up from there. Older Mac keyboards were anchored by a mix of Torx and 1.3mm Hex screws, aloof as one archetype of how one of these $.25 could prove useful.

Even if you don’t acquisition a Hex spiral in your Mac or peripheral, they’re advantageous for added things. I’ve best generally activate them handy for abbreviating furniture, such as the board my Mac sits on, or Hex screws on monitor/tablet-supporting stands. These about-face out to be almost accepted screws for assertive types of products.
Last and additionally atomic in this accumulating are the six Nut Drivers, alignment from 2.5mm to 5mm in size. These ample $.25 are finer the changed of the Hex/Allen bits, and advised to handle screws that attending like bulging hexagonal bolts — think Frankenstein’s neck. I don’t absolutely see these on electronics articles these days; they’re far added accepted in furniture, admitting not decidedly accepted these days, abnormally in these sizes.
Depending on how bit-obsessed you appetite to be, there are alike added busy sets out there, such as Tekton’s $36 135-piece set with a ratcheting screwdriver, Anytime’s $27 101-piece set focused on aegis screws, and $16 to $27 Delcast kits with Pentalobes and added tools. The $30 iFixit 54 Bit Disciplinarian Kit is in the average of the backpack price-wise, but focuses appealing able-bodied on the needs of Mac owners. Go with article added all-encompassing if your adjustment needs go aloft the Mac, or with a simpler Pentalobe-focused set if you’re alone absorbed in aperture iPhones.
If you’d like to apprentice about some of the added abstruse aegis screws out there, such as the Spanner head/Snake-eye, Bristol, or Double-square, this Wikipedia access is arranged with information.
Additionally, I’ve covered a lot of added Mac-related advancement capacity that account from compassionate the aegis screws discussed above. Check out a abounding account of my 9to5Mac guides, editorials, and reviews; if you bang on Older Posts at the basal of the page, you can see everything!
