Most tamper-resistant screw configurations rely on the common unavailability of corresponding drivers to reduce the likelihood of widespread tampering. True tamper-proof - rather than merely resistant - screw drives include the breakaway head and one-way screw drives.

In Japan, the male sizes are often designated as DTC-20, DTC-27, DTC-40 (discontinued) and DTC-45 corresponding to a respective screw head size of 3.2mm, 4.6mm, 6.4mm and 7.7mm; with the size of the screw measured across the widest portion of the mating part of the head. The most common sizes in use for consumer electronics are DCT-20 and DTC-27.Supadrive allow a small angular offset between the screw and the screwdriver. Pozidrive have to be directly in line" Spline drives were specified for 5, 6.3, 8, 10, 12, 14, 16, and 20mm size screws. [82] Its primary advantage is its ability to resist cam out, so it is used in high-torque applications, such as tamper-proof lug nuts, cylinder head bolts, and other engine bolts. Slot screw drives have a single horizontal indentation (the slot) in the fastener head and is driven by a "common blade" or flat-bladed screwdriver. This form was the first type of screw drive to be developed, and for centuries, it was the simplest and cheapest to make because it can just be sawed or filed. Additionally, it is unique because the slot head is straightforward to manufacture, and because it can be driven by a simple handtool. The slotted screw is commonly found in existing products and installations, along with use in simple carpentry work and in applications where minimal torque is needed. Slot screws are also used in the restoration of antique furniture, vehicles, and equipment. When a Phillips Is Not a Phillips Plus So Much More!". Instructables.

The Slotted/Pozidriv is slightly different from the Slotted/Phillips (PH/S), and good use requires special screwdrivers. [ citation needed] ACR Phillips II Plus [ edit ] Due to the difficulty of turning these fasteners without specialized (and uncommon) five-point wrenches such as hydrant wrenches, they are commonly used for tamper resistance by public utilities on water meter covers, natural gas valves, electrical cabinets, and fire hydrants. Some screws have heads designed to accommodate more than one kind of driver, sometimes referred to as combo-head or combi-head. The most common of these are a combination of a slotted/Phillips head.MTI Catalog" (PDF). moodytools.com. Archived (PDF) from the original on 2014-01-09 . Retrieved 2014-01-10. a b "Tork-Bolts".

The pentalobe screw drive is a five-pointed tamper-resistant system implemented by Apple in its products. [43] Apple's first use of the pentalobe drive was in mid-2009 to secure the battery in the MacBook Pro. Smaller versions are now used on the iPhone 4 and subsequent models, the MacBook Air (since the late 2010 model), the MacBook Pro with Retina Display and the 2015 MacBook. Pentalobe screw sizes include TS1 (also known as P2 or 0.8mm, used on the iPhone 4 and subsequent models), TS4 (also known as P5 or 1.2mm, used on the MacBook Air [since late 2010], the MacBook Pro with Retina Display and the 2015 MacBook) and TS5 (also known as P6 or 1.5mm, used on the 2009 MacBook Pro battery). The TS designation is ambiguous as it is also used for a Torq-set screw drive. The Recex drive system claims it offers the combined non-slip convenience of a Robertson drive during production assembly and Phillips for after market serviceability. The Phillips Screw Company offers both Phillips and Pozidriv combo heads with Robertson. [ citation needed] Slotted/Torx [ edit ]

The Phillips/square screw drive, also known as the Quadrex, Pozisquare screw drive, is a combination of the Phillips and Robertson screw drives. While a standard Phillips or Robertson tool can be used, there is also a dedicated tool for it that increases the surface area between the tool and the fastener so it can handle more torque.
