Value Collection 31334 Split Lock Washer 1 in Grade 5

Product Description

The VALUE COLLECTION 31334 is a Grade 5 steel split lock washer designed for 1-inch screw applications. The split lock design bites into mating surfaces under torque to resist loosening from vibration and thermal cycling. This washer features a zinc-plated finish for basic corrosion resistance in dry to mildly humid environments. With an inside diameter range of 1.003 to 1.024 inches and a maximum outside diameter of 1.656 inches, it is sized for standard 1-inch fastener assemblies. Thickness is 0.25 inches. Installers across mechanical, structural, and equipment-mounting applications rely on this type of washer as a routine fastener component.

This split lock washer is suited for general mechanical assembly work in residential and light commercial settings. Typical applications include equipment mounting, panel fastening, and structural connections where vibration or repeated loading could back out fasteners over time. It is commonly used by HVAC technicians, electricians, and plumbers when securing equipment to frames, pads, or structural members. The zinc-plated finish makes it appropriate for indoor and sheltered outdoor use where heavy corrosion exposure is not expected.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before torquing. Ensure the fastener, washer, and mating material ratings are compatible for the load and environment. Follow applicable codes such as NEC or IFGC when used in trade installations. Do not reuse a split lock washer that has been fully compressed flat, as the locking function will be diminished.
