Need a fastener that can stand up to the toughest industrial conditions? Choose this spring coil washer from RS PRO. It's made from steel and has a bright zinc-plated finish, so it's durable and resistant to rust and corrosion.
The washer's split coil design means it grabs the nut and locks in place for a firm hold that won't come loose, even after regular heavy movement or shocks. The coil ends absorb the screwdriver's turning force, so you can tighten the nut as much as you need to without damaging the washer.
The split visibly closes as you fix the fasteners on, allowing you to see when it's fully tightened. Coil washers like this are commonly used to assemble or repair heavy industrial machinery and equipment that's prone to vibration.
