Steel phillips pan head self tapping screw dacromat silver coated 

Product Description

Self-tapping screws are those that can form their own threads as they are driven into the material. Plastic requires a specially designed thread profile as tapping screws used with steel can result in residual stresses in the plastic that can degrade the structural integrity of the assembly. Plastic thread-forming screws give you more flexibility and quickly assemble components with fewer fasteners. When looking into self-tapping screws, the first step is to decide what type of self-tapping screws are best suited for the application.

Self-tapping screws have a wide range of tip and thread patterns, and are available with almost any possible screw head design. Common features are the screw thread covering the whole length of the screw from tip to head and a pronounced thread hard enough for the intended substrate, often case-hardened.

The type B tip is blunt and intended for use with a pilot hole, often in sheet materials. The lack of a sharp tip is helpful for packaging and handling and in some applications may be helpful for reducing the clearance necessary on the reverse of a fastened panel or for making more thread available on a given length screw.

Raw Material: Carbon Steel

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

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.

Dacromet

Dacromet® is a sacrificial zinc flake water-based coating system developed and applied to components to provide corrosion resistance.Dacromet is inorganic and firmly adhesive, made from water-based chemicals and passivated zinc and aluminium flakes in a binder. This is a patented chemistry and appears metallic silver in appearance. The coating is especially suited for thin layer thicknesses.
