Fastener Lockwasher

Fastener Lockwasher

This is a 1/2" split ring lock washer, a common fastener component used across various heavy equipment, including concrete mixers. The washer's split, helical design exerts spring force between the fastener's head and the substrate, creating friction and resistance to rotation. This prevents loosening caused by the intense vibration common in concrete mixer operations, ensuring critical components remain secure. It is a crucial, low-cost part for routine maintenance and repairs of bolted assemblies.

Key Features

• Split helical shape provides continuous pressure to resist loosening from vibration
• Hardened steel construction for durability
• Zinc-plated finish for corrosion resistance
• Compatible with standard 1/2" bolts and nuts
