Value Collection A410447 M12 Split Lock Washer 316 Ss 25pk

Product Description

The VALUE COLLECTION A410447 is an M12 metric split lock washer manufactured from 316 austenitic stainless steel to Grade A4 specification. Conforming to DIN 127B, this washer delivers reliable bolt load retention in metric fastener assemblies where corrosion resistance is a priority. The uncoated finish preserves the natural surface properties of the 316 alloy. With a minimum inside diameter of 12.2 millimeters, a maximum outside diameter of 21.1 millimeters, and a thickness of 2.5 millimeters, it is sized for M12 screw applications. Each package contains 25 washers.

This split lock washer is suited for use in marine, chemical, food processing, and outdoor industrial environments where exposure to moisture, salt, or corrosive agents makes 316 stainless steel the preferred material. Licensed trades including plumbers, pipefitters, and mechanical contractors use Grade A4 metric hardware when assembling pipe supports, equipment mounts, and structural connections subject to vibration or movement. The DIN 127B standard ensures dimensional consistency across metric fastener assemblies.

Compatibility

Designed for use with M12 metric fasteners in assemblies requiring DIN 127B split lock washers. Suitable wherever an M12 screw with 12.2 to 12.7 millimeter inside diameter clearance is specified.

Installation Notes

Install between the fastener bearing surface and the nut or bolt head per standard metric fastener practice. Verify that mating fasteners and hardware are compatible with 316 stainless steel to avoid galvanic corrosion in mixed-metal assemblies. Follow applicable mechanical or structural codes when used in load-bearing connections. No special tools are required for installation beyond standard hand or power wrenches appropriate to the M12 fastener size.
