DIN127 Zinc Plated Split Spring Lock Washers Steel Fasteners

This DIN127 spring lock washer is a split washer used under a bolt head or nut. When the fastener is tightened, the washer compresses and provides spring tension in the assembly. This structure helps increase friction and reduce the risk of loosening caused by vibration, movement, impact, or repeated mechanical loading.

The washer is made from steel, which provides suitable strength and elasticity for common industrial fastening. The surface treatment is zinc plated, giving the washer a silver galvanized appearance. Zinc plating helps protect the washer surface from general oxidation and makes it suitable for indoor, dry, and normal industrial environments.

The product is suitable for many fastening systems, including bolts, nuts, threaded rods, machine frames, brackets, equipment bases, construction plates, guardrails, racks, and repair assemblies. For buyers who need large‑volume fastener supply, this DIN127 spring washer can be packed in bags, boxes, cartons, and pallets according to order requirements.

Material and Grade Explanation

The washer is made from steel and follows the DIN127 spring washer standard. DIN127 defines the split spring washer structure and dimensional standard used for fastening assemblies. This product is not a bolt, so the grade should be understood as the washer standard level and fastening application type rather than a bolt property grade such as 8.8 or 10.9.

Steel is commonly used for spring lock washers because it provides suitable mechanical support, elastic fastening behavior, and stable bulk production. The washer should be selected according to the bolt size, nut size, working load, installation torque, vibration condition, and surface treatment requirement.

Zinc Plated Surface Treatment

The washer is supplied with a zinc plated finish. Zinc plating gives the washer a silver‑white metallic appearance and helps provide basic corrosion protection for general fastening environments.

This finish is suitable for indoor machinery, warehouse storage, dry construction hardware, metal brackets, equipment assembly, and general industrial applications. For outdoor or highly corrosive environments, buyers can specify stronger surface treatment requirements according to the project conditions.

DIN127 Split Spring Washer Design

DIN127 spring washers have a split opening and raised spring shape. During installation, the washer compresses under the tightening force of the nut or bolt head. The compressed washer creates elastic resistance and helps maintain fastening pressure.

This design is widely used in machinery, equipment, steel structures, construction hardware, vehicles, maintenance work, and industrial fastening systems where vibration or movement may cause standard fasteners to loosen over time.
