Material

Screws shall be made from alloy steel per ASTM F835

Hardness

½” diameter and smaller HRC 39-45 Over ½” HRC 37-45.

Zinc

Zinc electroplating is a corrosion-resistant coating that slows rusting by keeping out the moisture lingering in air molecules. It has a high-temperature tolerance of up to 120  and can be useful for applications requiring aesthetic details. The finish is smooth and silvery blue. Coated fasteners are RoHS compliant (hexavalent chromium-free).

Screws are baked within 1 hour after plating for 14 hours to reduce susceptibility to Hydrogen Embrittlement.  HE is unpredictable.  All plated lots are thoroughly tested prior to sale to further reduce incidence.
