Fastener Flatwasher 3/8-Gr8

Fastener Flatwasher 3/8-Gr8

This is a 3/8 inch Grade 8 flat washer, specifically engineered for high-tensile applications common in heavy machinery like concrete mixers. Made from through-hardened alloy steel, it provides a greater bearing surface to distribute the load of a bolt or nut, preventing damage to the mating surface and ensuring a secure joint under high clamping forces and vibration. Its zinc plating offers corrosion resistance, making it a durable component for routine maintenance and repair of various mixer systems.

Key Features
