Professional Applications & Engineering Value
These split lock washers provide critical vibration-damping performance in demanding industrial settings where fastener security is paramount. The high-strength steel construction and Rockwell C38 hardness ensure the washer maintains its spring tension and locking capability even under extreme vibration and thermal cycling conditions. The precision 0.45" internal diameter creates an optimal interference fit with 7/16" screws, preventing rotation while the split design applies continuous pressure against both the fastener and mating surface. This engineering solution effectively counters the primary causes of joint failure in machinery, automotive assemblies, and heavy equipment where vibration resistance is critical for operational safety and maintenance reduction.
Specification Summary & Compliance
This standard split lock washer features precise dimensions of 0.45" ID, 0.644" OD, and 0.140" thickness, manufactured to exacting ASME B18.21.1 specifications for dimensional accuracy and performance reliability. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The Rockwell C38 hardness rating guarantees consistent material properties and spring performance throughout the washer's service life.
