Value Collection MS35338-43 Split Lock Washer No. 10

Product Description

The VALUE COLLECTION MS35338-43 is a No. 10 split lock washer manufactured from spring steel with a yellow zinc dichromate finish. It meets Military Specification MS35338, making it suitable for applications where corrosion resistance and fastener retention under vibration are required. The washer measures 0.193 to 0.200 inches minimum inside diameter, 0.334 inches maximum outside diameter, and 0.047 inches thick. The split design creates a spring-tension bite against both the fastener and mating surface to resist loosening. Installers in mechanical, electrical, and structural assembly work rely on this style of washer where vibration or thermal cycling is a concern.

This washer is used with No. 10 machine screws and bolts in general-purpose fastening applications across residential and commercial construction, HVAC equipment assembly, electrical panel and conduit work, and light structural applications. The yellow zinc dichromate finish provides a baseline level of corrosion resistance suitable for indoor and protected outdoor environments. It is appropriate wherever MS35338-standard hardware is called out in a specification or replacement scenario.

Installation Notes

Installation requires no special tools beyond standard hand or power drivers. Place the washer between the fastener head and mating surface before torquing down. Ensure mating surfaces are clean and free of debris to allow full contact. Follow applicable assembly specifications or codes for final torque values, as this washer does not substitute for torque requirements defined in the governing standard.
