Product Information

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. The Phillips screw drive (specified as an ANSI Type I Cross Recess [9] and type H in ISO documentation) was created by John P. Thompson, who, after failing to interest manufacturers, sold his design to businessman Henry F. Phillips. [10] [11] Phillips is credited with forming a company ( Phillips Screw Company), improving the design, and promoting the adoption of his product. [10] The original 1932 patent [12] expired in 1966, but the Phillips Screw Company continued to develop improved designs.

JIS" or ISO 8764 standardized cruciform-blade screwdrivers are available for this type of screw, and should always be used to avoid head and driver damage. PH) (PZ) ISO 8764 PH drivers [31] are nearly identical to JIS B 1012 drivers. ISO 8764 has superseded JIS B 1012 in Japan as well as being used in many other countries. The standard specifies that drivers and bits are to be marked with a "PH" or "PZ" followed by the size number (000, 00, 0, 1, 2, 3), though not all manufacturers do this.

If you keep trying to drive a Y000 screw with a tool that doesn't grab well you'll strip the top of the screw and then you'll need to find a way to make a straight groove in the top which will allow you to remove the screw with a tiny slotted driver (flat head). There are a ton of problems that can arise as a result of this. Metal flakes can get lodged in between surface-mount components and do more damage to the device. Also you could slip and cause more damage. Etc. a b c "Unterschied zwischen Pozidrive und Superdrive"[Difference between Pozidriv and Supadriv] (in German). Goedkopeschroevenkopen.nl.

The applicable standards that govern the Torq-set geometry are National Aerospace Standard NASM 33781 and NASM 14191 for the ribbed version. The ribbed version is also known as ACR Torq-set. [84] Tri-angle [ edit ] 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.

According to needs, there are light-duty screwdrivers and heavy-duty screwdrivers. They have a flat tip. Although it can be powered or manually operated, the ‘cam-out effect’ of the slotted head makes power operation less common. Also called BNAE NFL22-070 after its Bureau de normalisation de l'aéronautique et de l'espace standard number. A cross-head screw with a two-step driver design, with the blade diameter stepping up at a distance from the point. The Slotted/Pozidriv is slightly different from the Slotted/Phillips (PH/S), and good use requires special screwdrivers.

Instead of twisting the screw with your wrist, you place the screw head against the screw and push it to tighten.

Hi-Torque slot drives were designed by Alcoa Fastening Systems, for situations where very high torque is needed, along with the ability to repeatedly install and remove the fastener. [7] The design features curved walls, unlike the straight-walled slot drive. The blade is the lower part of the shank. It is also known as a tip. This part is hardened and tempered.
