Value Collection 31323 Split Lock Washer No. 10 Grade 5 Steel

Product Description

The VALUE COLLECTION 31323 is a No. 10 screw split lock washer manufactured from Grade 5 steel with a zinc plated finish. Split lock washers are used in bolted assemblies to resist loosening caused by vibration and torque relaxation. The split design bites into the bearing surface and fastener head to maintain clamp load. This washer measures 0.193 to 0.200 inches inside diameter, 0.334 inches maximum outside diameter, and 0.047 inches thick. It is sized for No. 10 machine screws and is handled by electricians, plumbers, HVAC technicians, and general trade professionals in mechanical assembly applications.

This split lock washer is suited for residential and light commercial mechanical assemblies where No. 10 fasteners are used. Typical applications include equipment mounting, panel assembly, pipe hanger hardware, and electrical enclosure assembly. The zinc plated finish provides moderate corrosion resistance in indoor and sheltered environments. Each unit is sold individually with a minimum order quantity of 250 pieces, making this item appropriate for shop stock or bulk fastener replenishment.

Compatibility

Designed for use with No. 10 machine screws in standard inch-series bolted assemblies across HVAC, electrical, plumbing, and general mechanical applications.

Installation Notes

Install split lock washers between the fastener head and the bearing surface before torquing. Ensure mating surfaces are clean and free of debris to allow the washer to seat properly. Do not reuse split lock washers that have been fully compressed, as the locking action is reduced after full deflection. Follow applicable mechanical codes and equipment manufacturer guidelines when selecting fasteners for structural or pressure-bearing assemblies.
