Value Collection 67582767 5/16 in 316 Ss Split Lock Washer

Product Description

The VALUE COLLECTION 67582767 is a 5/16 inch split lock washer made from 316 stainless steel, designed to resist loosening under vibration and dynamic load. The helical spring-lock design bites into the bearing surface as the fastener is torqued, creating tension that resists backoff. With an inside diameter range of 0.314 to 0.322 inches and a thickness of 0.078 inches, this washer seats correctly on 5/16 inch fasteners used in mechanical, plumbing, and HVAC applications. Licensed tradespeople and maintenance technicians install these wherever corrosion resistance and secure fastening are both required.

This split lock washer suits residential and light commercial installations where 316 stainless steel is specified for corrosion resistance in wet, coastal, or chemically exposed environments. Typical applications include pipe hangers, equipment mounting brackets, electrical enclosure hardware, and HVAC unit fastening in outdoor or high-moisture conditions. It meets dimensional standards including ASME, ANSI, BS, DIN, JIS, and NFE, making it appropriate for jobs where standard compliance is required.

Key Features

• 316 stainless steel construction provides strong resistance to corrosion, pitting, and chloride exposure
• Spring-lock (helical) profile creates tension against fastener backoff under vibration
• Sized for 5/16 inch screws with inside diameter range of 0.314 to 0.322 inches
• Thickness of 0.078 inches provides consistent spring tension across the bearing surface
• Complies with ASME, ANSI, BS, DIN, JIS, and NFE dimensional standards
• Sold individually; minimum order quantity is 100 pieces

Compatibility

Designed for use with 5/16 inch screws and bolts in standard inch-measurement fastener systems where a spring-lock washer is specified.

Installation Notes

Installation requires no special tools beyond a standard wrench or driver sized to the mating fastener. Power down or de-energize any equipment before accessing fastener locations on electrical or HVAC components. Place the washer flat side down against the bearing surface with the split ends oriented so the helical gap faces up toward the fastener head or nut. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide reliable spring tension.
