Value Collection 42454 M8 Split Lock Washer Grade 8 Spring Steel

Product Description

The VALUE COLLECTION 42454 is a metric split lock washer designed for use with M8 fasteners in bolted assemblies where loosening from vibration or torque is a concern. Made from Grade 8 spring steel with a zinc plated finish, this washer delivers reliable tension and corrosion resistance in a compact form factor. The inside diameter runs 8.1 to 8.5mm, the maximum outside diameter is 14.8mm, and the washer thickness is 2mm. Hardness is rated at 44-51 HRC, giving it the spring back needed to maintain clamp load after tightening. It meets the DIN 127 fastener standard and is sized to the metric system of measurement.

This washer is suited for general mechanical, industrial, and light structural assembly work where M8 bolts or screws are used. Typical applications include equipment fabrication, machinery maintenance, HVAC equipment mounting, electrical enclosure assembly, and similar trade work requiring a reliable locking fastener component. It is sold individually with a minimum order quantity of 200 pieces.
