Product Information

Screw heads that feature the Phillips crosshead design may have rounded or flat tops. Phillips Head Screwdriver Sizes FAQ 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. The size of Phillips head screwdrivers is indicated by numbers, not measurements, which can make things confusing. Screws, too, are designated according to numbers from 0 to 24 that indicate the different sizes of the screw based on diameter. An Easy Guide to Phillips Head Screwdriver Sizes

Phillips Head Screwdriver History

The triple-square, also known as XZN, is a type of screw drive with 12 equally spaced protrusions, each ending in a 90° internal angle. The name derives from overlaying three equal squares to form such a pattern with 12 right-angled protrusions (a 12-pointed star). In other words, three Robertson squares are superimposed at a successive 30° rotation. The design is similar to that of the double-square—in both cases, the idea being that it resembles a square (Robertson) but can be engaged at more frequent angles by the driver bit. These screws can be driven with standard Robertson bits. A U-drive screw has a helical thread with an angle acute enough to be driven by a hammer or pressure from an arbor press, and thus has a domed head with no means of turning it. [92] These are most frequently driven into plastics with a pre-drilled pilot hole. 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 ] Spanner-Bolts". Loss Prevention Fasteners. Ultra Fasteners Inc.

The 12-pointed internal star shape superficially resembles the "double hex" fastener head, but differs subtly in that the points are shaped to an internal angle of 90° (derived from a square), rather than the 120° internal angle of a hexagon. In practice, drivers for the fasteners may be interchangeable, but should be examined carefully for proper fit before application of force. A hex key should not be used where a key of square cross-section is the correct fit. Different shaft lengths and handle sizes can make it easier to work on whatever you're working on. A longer shaft can allow you to access hard-to-reach areas where your hand won't fit. Phillips head screwdrivers are also made in very small sizes. They are used in precision work and are not commonly included in standard toolsets. Tri-Wing Screwdriver. "Tri-wing screwdriver: Types". Triwingscrewdrivers.com.

The Ultra-Lok, and Ultra-Lok II are some of these designs that use custom keyed drivers, which tend to be confined to industrial and institutional uses that are unavailable to the average layperson. Key-Rex screws are another design, and are used in such things as ballot boxes and bank vaults. [41] Consisting of a cross-slotted tip and a shaft, a Phillips head screwdriver works in almost an identical way to a single-slotted (flathead) screwdriver. Using any screwdriver takes very little skill, as all you have to do is fit the tip of the screwdriver into a nail and twist your wrist to unscrew and install screws. Any complete screwdriver set will feature both flat head and Phillips’s head screwdrivers, with the size of the drivers ranging from 0 to 4 while the handle and shaft will length vary. In a set, you might find a special stubby Phillips-head driver with a 1½-inch shaft, and several drivers with four-inch shafts as well.

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.
