Professional Applications & Engineering Value

Engineered for industrial machinery and heavy equipment applications, these zinc-plated steel clipped washers deliver critical performance where vibration resistance and corrosion protection are paramount. The unique clipped design provides positive locking action that prevents rotation in high-vibration environments such as automotive assemblies, construction equipment, and agricultural machinery. The Rockwell B40 hardness ensures the washer maintains its structural integrity under repeated loading cycles, while the zinc plating creates a sacrificial barrier against rust and environmental degradation. This combination of features makes these 5/16" washers ideal for applications requiring reliable, long-term fastening solutions that withstand harsh operating conditions without compromising performance or safety standards.

Specification Summary & Compliance
