Introduce

Hexagonal self tapping screws are used for fixing into metals and hard plastics. The hexagon head allows for increased fastening torque and reduces tool slippage during insertion.These screws cannot drill through metal and require a pilot hole to be pre-drilled before installation. A pilot hole is created by using a drill bit which is slightly smaller than the screw and the threads of the screw tap the metal or wood while the screw is being installed.

Hexagonal Self Tapping Screws

Feature

• Thread-Tapping: These screws do not require a pilot hole but one can be drilled to make fastening easier. Remember to make the pilot hole smaller than the diameter of the thread tapping screw. Thread-tapping screws remove material and create a path for the screw. The drawbacks to using this type of screw is when they are removed it can result in stripped threads. If you experience stripped threads you should use a larger thread-tapping screw when reattachment is made.

• Self tapping screws  cannot drill through metal and require a pilot hole.Self drilling screws eliminate the need for a pilot hole, but can tap as well.
• Self tapping screws have a wide range of tip and thread patterns, and are available with almost any possible screw head design.
