Plastite Screw Pan Phillips Head Steel Zinc Plating Screws Supplier

Plastite screw is one kind of self-tapping screw. The screws are mainly used in electronics. The screws are designed for reliable and secure fastening into materials such as plastic. Ever Hardware provides custom-made fasteners and customizable packaging.

The PLASTITE screw is designed to facilitate thread-forming in less-compressible plastics while providing high resistance to strip-out and pull-out.
Features
Tri-roundular configuration that allows displaced material to cold flow back into relief areas.
45° profile allows thread to penetrate deeply into plastic material
Single lead design and narrow helix angle lowers drive torque and failure torque in stiffer plastics
Benefits
Reduces possibility of boss failure
Increases product reliability
Eliminates need for inserts and lock washers
Minimizes radial stress
Allows design of thinner bosses
Generates strong mating threads
Resists vibration loosening
Reduces probability of strip-out and pull-out
Achieves wide differentials between drive and fail torque
Creates less stress on the boss

Zinc coatings prevent oxidation of the plastite screw by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate’s surface integrity as it is formed. Indeed, the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers. The majority of hardware parts are zinc-plated, rather than cadmium-plated. Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion-resistant, multi-layered coating of zinc-iron alloy and zinc metal.
