What Is a Triangle Screwdriver?
A triangle screwdriver is a screwdriver specially designed for use with triangular screws. A triangle screwdriver is a screw with a screw head whose screwdriver slot is shaped like a triangle (“screw” in this case does not only indicate the screw shape but also the smaller size screw product).
The symbol for a triangle screwdriver is “TA,” which may be stamped on the tip of the screwdriver.
Uses of Triangle Screwdrivers
Triangle screwdrivers are used exclusively for triangular screws and are therefore used in limited situations.
Triangular screws are relatively small screws used in many precision machines, such as computers, smartphones, and toys. The triangle screwdrivers are a tool dedicated to these screws.
Since there are few users of triangle screwdrivers and a few of them are sold, they were used to prevent tampering and disassembly. Today, however, they are readily available at home centers and other places. As a result, they may not serve that purpose sufficiently.
How to Select Triangle Screwdrivers
The following points should be considered in selecting triangle screwdrivers:
- Size-specific, Bit-Swapping Type
There are several sizes of triangle screwdrivers, including 1.6, 2.0, 2.3, and 3.0, etc. Dedicated screwdrivers for each size and screwdrivers with replaceable bits for each size are available and should be selected according to the intended use. - Grip Shape and Material
Grips come in various shapes, sizes, and lengths, and are made of elastomer resin or rubber. It is important to select a grip that is non-slip and easy to apply force according to the uses of the tool. - Material
The material of the tip is an important factor in tightening force and tool life. Some tools are made of chrome molybdenum vanadium alloy steel, or ASTM A681 S2 tool alloy steel, which has high hardness, high strength, and high corrosion resistance. - Other
Some have a magnetic tip that allows screws to be tightened and removed without falling. Others have interchangeable bits that allow the use of bits other than triangular screws, and some have a ratcheting mechanism.
