Stainless Steel Wood Screws Deck Screws Pan Washer Head Fasteners

Stainless steel wood screws are made of stainless steel A1/A2/A3/A4 used when connecting an application with only wood materials. These wood screws boast coarse threading, but that threading does not encompass the length of the screw. Normal wood screws thread as they enter the wood, where lag screws require a hole to be drilled first. Ever Hardware provides custom-made fasteners and customizable packaging.

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required.
Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide; and, because of the greater volume of the iron oxide, this tends to flake and fall away. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal’s internal structure. Passivation occurs only if the proportion of chromium is high enough and oxygen is present.

The pan washer head design could possibly be the most versatile head design available. It combines the advantages of the pan head but has a washer built onto the head to increase head diameter and prevent over driving in softwoods while providing a maximum bearing surface.
