Professional Applications & Engineering Value
This 18-8 stainless steel split lock washer delivers critical vibration resistance in demanding industrial environments where fastener security is paramount. The standard split lock design creates continuous spring tension against both the bearing surface and fastener, effectively preventing rotational loosening caused by machinery vibration, thermal cycling, and dynamic loads. Engineered specifically for No. 12 screw applications, the precise 0.227" internal diameter ensures proper fit and maximum contact surface. The corrosion-resistant properties of 18-8 stainless steel make these industrial washers ideal for harsh environments including chemical processing, marine applications, and outdoor equipment where moisture and corrosive elements would compromise ordinary fasteners.
Specification Summary & Compliance
This split lock washer features inch system dimensions with 0.227" internal diameter, 0.331" outer diameter, and 0.078" thickness, engineered to standard lock washer specifications for No. 12 screw sizes. Manufactured from 18-8 stainless steel with Rockwell C35 hardness rating, the washer complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for global industrial applications.
