Value Collection MS35338-42 Split Lock Washer 8 Screw

Product Description

The VALUE COLLECTION MS35338-42 is a number 8 screw split lock washer manufactured from spring steel with a yellow zinc dichromate finish. It functions by applying spring tension under a fastener head or nut to resist loosening caused by vibration and dynamic loads. The washer meets military specification MS35338, making it suitable for demanding fastening applications where standard hardware is not specified. Inside diameter ranges from 0.167 to 0.174 inches, the maximum outside diameter is 0.293 inches, and the thickness is 0.04 inches. Electricians, HVAC technicians, pipefitters, and general maintenance trades install these washers wherever vibration-resistant fastening is required.

This washer is used in a wide range of industrial, commercial, and residential applications where a number 8 fastener is used in conjunction with a locking element. Typical install scenarios include panel and bracket mounting in electrical enclosures, HVAC equipment, mechanical assemblies, and structural connections exposed to vibration. The yellow zinc dichromate finish provides moderate corrosion resistance for indoor and light-duty outdoor environments. These washers are sold individually but carry a minimum order quantity of 100 pieces per order.

Installation Notes

Split lock washers are installed by a licensed electrician, HVAC technician, or mechanical trade professional as part of a bolted or screwed fastener assembly. Always de-energize and lock out equipment before accessing any fastener points inside electrical enclosures or mechanical panels. Place the washer between the fastener head or nut and the mating surface so the split ends bite into both surfaces when the fastener is tightened. Do not reuse a lock washer that has been fully compressed flat, as it will no longer provide effective locking tension.
