Value Collection 33569 Split Lock Washer 1 in Grade 5 Steel

Product Description

The VALUE COLLECTION 33569 is a Grade 5 steel split lock washer sized for 1-inch screws and bolts. Split lock washers work by biting into the mating surface and fastener bearing face under load, resisting loosening caused by vibration and torque relaxation. This washer is uncoated carbon steel, appropriate for general mechanical and structural assembly applications. The inside diameter ranges from 1.003 to 1.024 inches, the maximum outside diameter is 1.705 inches, and the thickness is 0.306 inches. Plumbers, electricians, HVAC mechanics, and general maintenance technicians use split lock washers throughout equipment installation and panel assembly work.

This washer is suited for residential and light commercial mechanical installations where a 1-inch fastener requires axial load retention and vibration resistance. Typical applications include equipment mounting, pipe hanger hardware, electrical enclosure assembly, and structural fastening where a standard flat washer alone does not provide adequate locking action. The uncoated finish is appropriate for indoor or protected environments where corrosion exposure is minimal.

Key Features

• Grade 5 steel construction provides reliable strength for general mechanical fastening
• Split-ring design bites into fastener and mating surface to resist loosening under vibration
• Inside diameter range of 1.003 to 1.024 inches fits standard 1-inch fastener shanks
• Maximum outside diameter of 1.705 inches suits standard countersunk and through-hole applications
• Thickness of 0.306 inches delivers consistent spring tension under load
• Uncoated finish for use in dry or protected indoor environments

Compatibility

Designed for use with 1-inch screws and bolts in general mechanical, structural, and equipment assembly applications where a split lock washer is specified.

Installation Notes

Split lock washers are installed between the fastener bearing face and the mating surface before final torque is applied. Always de-energize or isolate any system before working on fastened assemblies in electrical or mechanical enclosures. Use the appropriate drive tools and follow applicable codes such as NEC for electrical installations or IFGC for gas equipment mounting hardware. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide effective locking action.
