Value Collection 47205 M10 Split Lock Washer Ss Din 127B 50pk

Product Description

The VALUE COLLECTION 47205 is an M10 metric split lock washer manufactured from 18-8 austenitic stainless steel, Grade A2, conforming to DIN 127B. Split lock washers are installed under fastener heads or nuts to resist loosening caused by vibration and dynamic loading. The helical split design bites into both the fastener bearing surface and the mating material, maintaining clamp load over time. With an inside diameter range of 10.2 to 10.7 millimeters, a maximum outside diameter of 18.1 millimeters, and a thickness of 2.2 millimeters, this washer is sized for M10 fasteners. Each package contains 50 washers.

This washer is suited for mechanical, plumbing, HVAC equipment assembly, electrical enclosure work, and general industrial fastening where corrosion resistance is required. Grade A2 stainless steel performs well in wet, humid, and mildly corrosive environments, making it a common choice for outdoor installations, equipment rooms, and coastal service conditions. It is installed by HVAC technicians, plumbers, electricians, and millwrights wherever M10 fasteners are used and vibration resistance or corrosion resistance is a requirement.

Compatibility

Designed for use with M10 metric fasteners in applications requiring a DIN 127B split lock washer in 18-8 stainless steel.

Installation Notes

Install with the split ends oriented to bite into the fastener bearing surface and the mating part as the fastener is torqued down. Do not reuse split lock washers that have been fully flattened, as the locking action is reduced. Fastener installations should comply with applicable mechanical and equipment codes for the trade performing the work. Wear appropriate hand protection when handling bulk hardware.
