DIN 6928 Hex Head Self Tappers Screw Hex Flange Head Cap With Big Flat Washer

Steel phillips hex flange head self tapping screw with big flat washer blue zinc 

Product Description

Tapping screws are designed to cut their own hole as it is screwed into the materials. This creates a good snug fit between the mating threads and also allows the parts to be reassembled if necessary.

Self-Tapping

Cuts its own thread while being driven into the mating material. It makes a small hole while entering the material which creates a tight friction fit between the threads. This helps fight vibration loosening and allows the parts to be taken apart if needed. Mostly used in 1-2-layer thin gage sheet metal applications.

Flanged head

A flanged head can be any of the above head styles (except the countersunk styles) with the addition of an integrated flange at the base of the head. This eliminates the need for a flat washer.

Raw Material: Carbon Steel

Carbon steel is a steel with carbon content up to 2.1% by weight.

As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however, it becomes less ductile. Regardless of the heat treatment, a higher carbon content reduces weldability. In carbon steels, the higher carbon content lowers the melting point.

The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance.

Case hardening processes harden only the exterior of the steel part, creating a hard, wear resistant skin (the "case") but preserving a tough and ductile interior.

Galvanization

Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting.
