Value Collection 31337 Split Lock Washer 1-1/2 in Grade 5

Product Description

The VALUE COLLECTION 31337 is a Grade 5 steel split lock washer sized for 1-1/2 inch screws and bolts. Split lock washers are installed under a nut or bolt head to resist loosening caused by vibration and torque relaxation. The helical split design bites into the bearing surface and the fastener, maintaining clamp load in mechanical assemblies. This washer is measured in the inch system and suits standard fastener applications across HVAC, plumbing, electrical, and general mechanical installations where a 1-1/2 inch screw size is specified.

This split lock washer is suited for use in light commercial and residential mechanical assemblies where Grade 5 steel hardness meets the load requirements. Typical applications include equipment mounting, panel securing, and structural fastener assemblies in trade installations. Sold individually, with a minimum order quantity of 25 pieces, making it appropriate for service stock or job-lot procurement.

Key Features

• Grade 5 steel construction provides strength suitable for standard mechanical fastening applications
• Helical split design resists vibration-induced loosening
• 1-1/2 inch screw size fits standard inch-system fasteners
• Inch measurement system for compatibility with standard SAE fastener sets
• Minimum order quantity of 25 units supports service van or shop stock replenishment

Compatibility

Designed as a standard split lock washer for use with 1-1/2 inch screw and bolt assemblies in inch-system fastener applications across mechanical, HVAC, plumbing, and electrical installations.

Installation Notes

Split lock washers are installed by placing the washer onto the fastener shank before threading into the receiving material, with the split gap positioned so the washer can compress flat under final torque. Power down or de-energize any equipment before accessing fastener assemblies on live systems. Use the appropriate drive tool for the fastener head type to avoid damaging the washer seating surface. Follow applicable mechanical codes and equipment manufacturer torque guidelines when securing structural or equipment-mounting fasteners.
