Professional Applications & Engineering Value
This split lock washer is engineered from black-oxide steel to address common industrial challenges like vibration-induced fastener failure. The split design creates a spring-like action that maintains constant pressure, countering loosening in machinery, automotive, and electrical enclosures. With Rockwell C38 hardness, it withstands cyclic stresses without deforming, while the black-oxide coating resists rust in humid or corrosive environments. Ideal for No. 4 screw applications, it ensures long-term reliability in assemblies subject to dynamic loads, reducing downtime and maintenance needs. The ASME B18.21.1 certification provides assurance of dimensional accuracy and performance consistency for engineering teams.
Specification Summary & Compliance
This washer meets ASME B18.21.1 specifications for standard split lock washers, with precise inch dimensions: 0.117" ID, 0.173" OD, and 0.022" thickness. Manufactured from carbon steel with a black-oxide finish, it complies with industry standards for hardness (Rockwell C38) and is suitable for use in assemblies requiring reliable vibration resistance. The product adheres to common industry regulations, including RoHS and REACH, ensuring environmental and safety compliance.
