Japanese Industrial Standard (JIS) cross-head screwdrivers are still another standard, often inaccurately called Japanese Phillips. Compatible screw heads are usually identifiable by a single depressed dot or an "X" to one side of the cross slot. This is a screw standard throughout the Asia market and Japanese imports. The driver has a 57° point with a flat tip.

A correctly sized JIS driver will engage at full depth into a Phillips or Pozidriv head screw slightly loosely, but without damage. JIS heads are often identified by a single dot or an "X" to one side of the cross slot. [30] Unlike JIS, the ISO 4757 standard for cross-head screws does not specify a dot on the screw head. [33] Phillips II [ edit ] This drive type has the disadvantage of not being as precisely controlled as can be obtained by proper use of a torque wrench; applications may still fail due to either too little torque being applied to correctly fasten the joint, or too much torque being required to shear the head, resulting in damage to the material being fastened.

While they are distinguished under close inspection by the angle at the tip of each of the 12 points (with a 90° angle on the XZN, instead of 60°) the general similarity and ability to insert the wrong tool can cause damage to the head. Reed and Prince, also called Frearson, is another historic cross-head screw configuration. The cross in the screw head is sharper and less rounded than a Phillips, and the bit has 45° flukes and a sharper, pointed end. Also, the Phillips screw slot is not as deep as the Reed and Prince slot. [19] [20] [21] In theory, different size R&P screws fit any R&P bit size. [22] Pozidriv [ edit ] Phillips and Pozidriv compared This unique tip design is made specifically to fit into corresponding Phillips head screws, which have corresponding X-shaped slots where the screwdriver fits. This unique design creates a firm hold between the screw and screwdriver, which prevents slipping. What is the smallest Phillips size? Reed & Prince Manufacturing Corporation: Welcome".

Sizes are: M4, M5, M6, (M7), M8, (M9), M10, (M11), M12, (M13), M14, (M15), M16, (M17) and M18 (the sizes in parentheses are less commonly used, but they do exist). Despite the similar naming scheme to metric fasteners, there is no correlation between the name of the size and the dimensions of the tool. Some sizes (at least M14, M16, M18) are also available in a tamperproof version (with a center hole) When the screw is stripped, the job will become much more difficult. Using the wrong screwdriver for the job at hand could also destroy your screwdriver. Further ReadingThe Phillips head screwdriver was created and patented by Henry Phillips in the 1930s and was originally used on the 1936 Cadillac. The great thing about it is that unlike the flat head screw (with a single ridge at its tip to slide into a screw with one slot), the Phillips screwdriver is self-centering. Its “X” design won’t slip out of the X-slotted screw. Instead, it grips the screw firmly in the center, provided it’s the suitable size for the screw. The Type II (Conical/Connie) design adds a conical cup that receives a centering pin on the driver, improving the alignment of the driving tool to the fastener recess. This small screwdriver is used in small projects, such as putting together crafting kits or little items like jewelry boxes. #2

The 6 screw is often used in smaller furniture items and crafts. The 8 is a popular all-purpose screw that is found in all sorts of projects, including light construction work. #3 Frauenfelder, Mark (2011-01-20). "Apple's diabolical plan to screw your iPhone".

The tip of a Phillips head will have pointed edges and a noticeable X shape.

The length of the metal that runs from the handle to the tip is the shank. It is usually made chrome, steel, or another metal and needs to withstand the force applied by your hand. The shank and the handle need to be connected strongly so that it doesn’t fall off even while applying high pressure on the handle. Some models even have shanks that reach the full length of the handle. This is useful when a hammer is used to strike the end of the handle.
