Metric Stainless A4 (316) Split Lock Washer, DIN 127B
Our Metric Stainless Steel A4 (316) Split Lock Washers manufactured to DIN 127B are corrosion‑resistant locking components designed to help prevent loosening in bolted assemblies subjected to vibration or movement. Made from A4 stainless steel (Type 316), these lock washers offer superior resistance to corrosion, chlorides, saltwater, and harsh environmental exposure.
The DIN 127B split (helical) lock washer design provides spring tension when compressed under a fastener, helping maintain preload and resist rotation. This locking action improves joint reliability while remaining compatible with standard metric bolts and nuts. Stainless 316 construction ensures long service life in demanding environments where standard carbon steel or 18‑8 stainless washers may not be sufficient.
Engineered for durability and dependable locking performance, A4 Stainless DIN 127B Split Lock Washers are commonly used in marine hardware, chemical processing equipment, outdoor structures, machinery, and general industrial assemblies. Their spring‑like action helps compensate for thermal expansion, vibration, and settling, while the 316 stainless material provides excellent corrosion resistance in moisture‑ and chemical‑exposed conditions. Available in a full range of metric sizes, these lock washers provide a reliable fastening solution for OEM production, maintenance, and repair operations requiring both locking capability and corrosion resistance.
