Value Collection A410446 M10 Split Lock Washer 316 Ss 25pk

Product Description

The VALUE COLLECTION A410446 is a metric split lock washer sized for M10 fasteners, manufactured from 316 austenitic stainless steel to Grade A4 specifications. With a minimum inside diameter of 10.2mm and a maximum of 10.7mm, it fits M10 screw shanks with standard metric clearance. The 18.1mm maximum outside diameter and 2.2mm thickness meet DIN 127B dimensional standards. The bright, uncoated finish retains the natural corrosion resistance of 316 stainless, making this washer appropriate for wet, coastal, or chemically aggressive environments. Each package contains 25 washers.

Split lock washers in this configuration are used in mechanical and structural assemblies where vibration loosening is a concern. The helical split design bites into the mating surface and the fastener bearing face under torque load, resisting rotational loosening. This washer is suited for use in HVAC equipment mounting, plumbing fixture connections, electrical panel and enclosure hardware, and general industrial or marine fastening applications where 316 stainless is specified for corrosion resistance.

Key Features

Compatibility

Designed for use with M10 metric fasteners in assemblies requiring DIN 127B split lock washers. Suitable wherever a metric Grade A4 stainless lock washer is specified.

Installation Notes

Install between the fastener head or nut and the mating surface per standard assembly practice; do not place a flat washer between the split lock washer and the fastener bearing face unless the assembly drawing specifies it. Ensure all mating hardware is compatible stainless or corrosion-resistant material to avoid galvanic corrosion in wet service. Follow applicable fastener torque specifications for M10 hardware as defined by the equipment manufacturer or applicable code. Consult IFGC, IPC, NEC, or equipment OEM documentation as appropriate for the specific installation.
