Value Collection C713072 Split Lock Washer Grade 8 Steel

Product Description

The VALUE COLLECTION C713072 is a Grade 8 steel split lock washer sized for 1-1/2 inch screws and bolts. Split lock washers create tension between a fastener and the mating surface, resisting loosening caused by vibration and thermal cycling. This washer is uncoated and carries a Grade 8 material rating, making it appropriate for high-strength bolted connections in mechanical, structural, and equipment-mounting applications. Each package contains 10 washers. The inside diameter ranges from 1.504 to 1.534 inches, the maximum outside diameter is 2.419 inches, and the thickness is 0.375 inches.

These split lock washers are used in trade installations where high-clamping-force fastener assemblies are required. Common applications include equipment bases, structural brackets, conduit supports, mechanical room installations, and industrial machinery mounting. The Grade 8 steel construction suits applications where standard low-carbon washers are inadequate under load. They are installed by electricians, pipefitters, millwrights, and general mechanical tradespeople working with 1-1/2 inch fastener assemblies.

Compatibility

Designed for use with standard 1-1/2 inch screws and bolts requiring a split lock washer in inch-measurement fastener assemblies.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before final torque is applied. Power down or de-energize equipment before working on any fastened assembly in electrical or mechanical systems. Use the appropriate drive tools and follow applicable codes such as NEC or AISC guidelines for structural and electrical fastening. Do not reuse a split lock washer that has been fully compressed flat, as it will no longer provide effective locking tension.
