• Zinc-plated steel construction provides excellent corrosion resistance for extended service life in demanding industrial conditions
• Rockwell C40 hardness rating ensures exceptional durability and spring-back performance under repeated loading cycles
• Precision-engineered dimensions (0.773" ID, 1.75" OD) guarantee perfect fit for 3/4" screw applications
• Heavy-duty spring design delivers consistent clamping force across varying thermal and mechanical stresses
• Full regulatory compliance with RoHS 3 and REACH standards ensures environmental responsibility and global market acceptance
• Optimized thickness range (0.127-0.141") provides reliable performance while accommodating manufacturing tolerances

Professional Applications & Engineering Value

This spring lock washer delivers critical engineering value in applications where vibration-induced loosening compromises assembly integrity. The zinc-plated steel construction combats corrosion in harsh environments, while the Rockwell C40 hardness ensures the spring maintains its tension-holding capability through countless stress cycles. Engineered specifically for 3/4" screw applications in heavy machinery, construction equipment, and industrial assemblies, this washer's split-ring design creates constant upward force that counters rotational loosening. The 1.75" OD provides optimal bearing surface distribution, making it ideal for high-torque applications where reliable vibration resistance is non-negotiable for operational safety and reduced maintenance intervals.
