Professional Applications & Engineering Value

These split lock washers deliver critical vibration resistance in demanding industrial environments where fastener security is paramount. Manufactured from 18-8 stainless steel, they provide exceptional corrosion resistance for applications exposed to moisture, chemicals, or outdoor conditions. The standard split lock design creates continuous spring tension that compensates for thermal expansion, vibration, and material relaxation. With precise 0.227" ID and 0.377" OD dimensions specifically engineered for No. 12 screws, these washers ensure perfect fitment in machinery, electrical enclosures, automotive assemblies, and industrial equipment where reliable fastening prevents costly downtime and maintenance.

Specification Summary & Compliance

This split lock washer features dimensional specifications of 0.227" inner diameter, 0.377" outer diameter, and 0.056" thickness, manufactured to ASME B18.21.1 standards for consistent performance. The product maintains Rockwell C35 hardness for optimal spring characteristics and meets comprehensive compliance requirements including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance.
