Nord-Lock Wedge-Locking Washers & Bolt Securing Systems

Bolted joint failure from vibration loosening is a leading cause of unplanned downtime in rotating machinery, rail, mining and process plant -- and Nord-Lock Group's wedge-locking technology directly addresses this problem. Unlike spring washers that rely on friction or tension, Nord-Lock washers use a cam-wedge mechanism: when the bolt attempts to loosen, the washer pairs create resistance greater than the bolt tightening torque, making spontaneous loosening mechanically impossible. Nord-Lock products are specified by OEMs and maintenance engineers in rail, mining, wind energy and heavy vehicle applications where vibration-induced loosening is unacceptable. AIMS Industrial stocks Nord-Lock washer systems in carbon steel and stainless steel for critical fastener applications.

Nord-Lock Wedge-Locking Washers

Nord-Lock's wedge locking washer pairs are available in the full metric range from M5 to M64 -- in standard carbon steel, stainless 316 and Super Alloy for corrosive environments.

• Nord-Lock Standard Wedge-Locking Washers (Steel): Cam-wedge locking pairs for structural and machinery bolted joints; carbon steel with zinc-flake coating for corrosion resistance in general industrial environments
• Nord-Lock Stainless Steel Washers (316): 316L austenitic stainless steel wedge washers for marine, food processing and chemical applications where galvanic corrosion from contact with fasteners is a concern

Nord-Lock X-Series & Spiralock Thread Locking

Nord-Lock Group's extended product range includes the X-Series for extreme vibration and Spiralock thread technology for blind-hole applications.

• Nord-Lock X-Series Washers: Extended clamping force washer system with increased cam angle for extreme vibration applications including rail track bolting and rotary equipment access covers on heavy plant
