Professional Applications & Engineering Value
These 316 stainless steel split lock washers deliver critical vibration resistance in demanding industrial environments where thermal cycling, mechanical stress, and corrosive elements threaten fastener integrity. The split lock design creates continuous spring tension that compensates for material relaxation and prevents rotational loosening - a common failure point in machinery, automotive assemblies, and marine equipment. Manufactured to DIN 7980 standards with precise metric dimensions (12.7mm ID × 18mm OD), these washers ensure reliable performance in M12 fastening systems while the 316 stainless steel composition provides superior resistance to chlorides, chemicals, and atmospheric corrosion compared to standard stainless grades.
Specification Summary & Compliance
This split lock washer features metric dimensions with 12.7mm internal diameter, 18mm outer diameter, and 2.3-2.7mm thickness range, engineered specifically for M12 screw applications. Manufactured in compliance with DIN 7980 specifications for dimensional accuracy and performance requirements. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations regarding substance restrictions, making it suitable for industrial applications with strict environmental and safety requirements.
