S-92148A339 17 mm ID x 27.4 mm OD DIN 127B Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance ensures fasteners remain securely locked even under dynamic loads and machinery vibrations
• Corrosion-resistant black-oxide 18-8 stainless steel provides excellent durability in humid or chemically aggressive industrial environments
• Precise metric sizing (17mm ID, 27.4mm OD) guarantees perfect fit and uniform pressure distribution for M16 screw applications
• DIN 127B compliance delivers consistent quality and reliable spring action for industrial locking performance
• Optimized thickness (3.3-3.7mm) maintains effective spring tension while accommodating standard assembly clearances
• RoHS 3 and REACH compliance meets strict environmental regulations for safe use in global manufacturing and export applications
• Split lock design creates continuous axial force that prevents loosening from thermal cycling and mechanical shock

Professional Applications & Engineering Value

Engineered for demanding industrial applications where vibration-induced loosening compromises safety and operational integrity, these M16 split lock washers provide reliable locking performance through their spring-steel action. The black-oxide coated 18-8 stainless steel construction resists corrosion in manufacturing plants, marine equipment, and outdoor machinery while maintaining consistent clamping force. As DIN 127B compliant metric fasteners, they ensure dimensional accuracy for M16 threaded components in assembly lines, heavy machinery, and transportation equipment where vibration resistance is critical. The split design creates continuous tension that compensates for thermal expansion and mechanical settlement, making them ideal for bolted connections subject to dynamic loading cycles.

Specification Summary & Compliance
