Spring Washer Din127

DIN127 spring washer is a standard split lock fastener designed to prevent bolts and nuts from loosening under vibration and mechanical impact.

Materials & Finishes: High-quality carbon steel with zinc plating or black oxide; 304/316 stainless steel with passivation for rust resistance. Full metric sizes M2–M36, custom specifications supported.

Features: Split elastic structure generates sustained axial tension between the nut and workpiece, boosting friction to deliver reliable anti-loosening effect. Standard dimensions perfectly match common metric bolts and nuts.

Selling Points: Stable locking performance, easy assembly, cost-effective for bulk use; sufficient inventory, strict quality control and competitive factory direct price.

Applications: Widely used in machinery, automotive, electrical equipment, metal structures and all vibration-prone industrial fastening scenarios.
