Value Collection -36745-1 High Collar Split Lock Washer

Product Description

The VALUE COLLECTION -36745-1 is a high collar split lock washer designed for use with 1 inch screws. Made from uncoated steel, this washer features a helical split design that creates spring tension under a fastener head or nut, resisting loosening caused by vibration and torque. The inside diameter ranges from 1.017 to 1.042 inches, the maximum outside diameter is 1.483 inches, and the thickness is 0.25 inches. Sold in a package of 25, these washers are suited for general mechanical assembly, structural fastening, and maintenance applications across industrial and commercial trades.

High collar split lock washers are used where additional locking height is required compared to standard split lock washers. The increased collar height provides greater spring force, making them appropriate for heavier fastening applications in steel fabrication, equipment assembly, HVAC structural mounting, and general mechanical construction. These uncoated steel washers are intended for dry or protected environments where corrosion resistance is not a primary requirement.

Installation Notes

Installation is performed by mechanics, millwrights, pipefitters, and general tradespeople as part of bolted assembly work. Power down or de-energize any equipment before disassembling fastened joints. Place the washer between the fastener head or nut and the mating surface, with the split ends oriented to bite into both surfaces as the fastener is tightened. Use only in environments appropriate for uncoated steel, as this finish provides no corrosion protection.
