• Reliable compliance with ASTM F436 Type 1 standards, guaranteeing consistent quality and mechanical properties for structural applications.
• Environmental safety assurance through RoHS 3 and REACH compliance, meeting strict regulations for hazardous substance restrictions.
• Precise fit for 1" screw sizes with standardized inch measurements, ensuring easy installation and secure fastening in assemblies.
• Robust thickness range of 0.136-0.177" providing optimal strength and stability for demanding construction and machinery uses.

Professional Applications & Engineering Value

This heavy-duty flat washer is engineered to address common industrial challenges such as fastener loosening, surface damage, and corrosion-induced failures. Constructed from hot-dipped galvanized steel, it offers a thick, protective zinc layer that resists rust and extends service life in outdoor or high-moisture settings like construction, bridges, and machinery. The precise 1.062" ID and 2" OD ensure even load distribution, preventing bolt embedment and maintaining joint integrity under dynamic stresses. Meeting ASTM F436 Type 1 specifications, it provides reliable performance in structural bolting applications, while its Rockwell C38 hardness withstands wear, making it ideal for repetitive disassembly and heavy-load scenarios in manufacturing and infrastructure projects.
