S-93925A427 17 mm ID x 26 mm OD DIN 6797 Internal-Tooth Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through internal tooth design that bites into mating surfaces to prevent loosening under dynamic loads
• Enhanced corrosion protection with zinc-plated steel construction for extended service life in demanding industrial environments
• Precision dimensional accuracy with 17mm ID and 26mm OD ensuring perfect fit for M16 screw applications
• Exceptional mechanical strength from Rockwell C42 hardness rating maintaining tooth integrity under high clamping forces
• Reliable compliance with DIN 6797 standards guaranteeing consistent performance and interchangeability
• Environmental responsibility through RoHS 3 and REACH compliance for safe use in regulated industries
• Optimized thickness range (1.0-1.4mm) providing ideal spring action while maintaining structural stability

Professional Applications & Engineering Value

This M16 internal tooth lock washer delivers critical engineering solutions where vibration-induced fastener failure poses significant operational risks. The zinc-plated steel construction combines corrosion resistance with mechanical durability, while the precisely engineered internal tooth configuration creates multiple biting points that resist rotational movement more effectively than standard washers. Engineered to DIN 6797 specifications, this washer maintains secure fastening in heavy machinery, automotive assemblies, and industrial equipment where constant vibration would compromise ordinary fasteners. The Rockwell C42 hardness ensures teeth maintain their biting capability through repeated installation cycles, providing reliable performance in maintenance-critical applications where disassembly and reassembly are frequent requirements.
