Description

5/8" Conquest Split Lock Washer - 18-8 Stainless Steel

This 5/8" split lock washer is ideal for securing larger fasteners in vibration-prone or corrosive environments. Its 18-8 stainless steel build provides durability and resistance to rust in marine, chemical, and outdoor applications. The helical spring shape maintains clamping force under load, helping ensure that bolts stay tight over time.

Install beneath the fastener head or nut and torque until slight compression locks it in place.

This washer keeps connections tight in harsh, high-vibration settings where bolt failure is not an option.

just what I wanted and only what I wanted

I got the bolts, nuts and washers I needed to add a more robust safety catch to my pro leg press. This personal project was one I had to put off because local shops (lowes, home depot) did not have the parts. I got them from fasteners plus fast in multiple mail orders.
