Value Collection LW7X01200-100BX M12 Split Lock Washer Ss

Product Description

The VALUE COLLECTION LW7X01200-100BX is an M12 metric split lock washer manufactured from 18-8 austenitic stainless steel, Grade A2. Split lock washers are installed under a fastener nut or bolt head to resist loosening caused by vibration and torque relaxation. This washer measures 12.2 to 12.7 mm minimum-to-maximum inside diameter and 21.1 mm maximum outside diameter, with a thickness of 2.5 mm. It conforms to DIN 127B, the standard governing metric split lock washers. Plumbers, pipefitters, HVAC technicians, and electricians use these washers in stainless fastener assemblies where corrosion resistance is required.

This washer is suited for M12 fastener applications in corrosive or wet environments, including plumbing, HVAC equipment mounting, electrical enclosures, and general industrial assembly. The 18-8 austenitic stainless steel construction makes it appropriate for both indoor and outdoor installations where carbon steel hardware would be subject to rust or staining. Sold in a minimum order quantity of 100 pieces, this washer is a practical stock item for shops and service fleets that regularly work with M12 metric fasteners.

Compatibility

Designed for use with M12 metric screws and bolts. Conforms to DIN 127B and is intended for metric fastener assemblies where an austenitic stainless steel split lock washer is specified.

Installation Notes

Install this washer between the fastener head or nut and the mating surface before final torque is applied. Ensure the fastener and mating hardware are also stainless steel or a compatible metal to avoid galvanic corrosion in wet environments. Follow applicable codes such as NEC or IPC when incorporating fastener hardware into electrical or plumbing assemblies. Do not mix with carbon steel fasteners in continuously wet or chemically active environments.
