Value Collection HLW0X0500-100BX M5 Lock Washer Ss

Product Description

The VALUE COLLECTION HLW0X0500-100BX is a metric high collar split lock washer sized for M5 fasteners. Made from 18-8 austenitic stainless steel meeting Grade A2 classification, it delivers corrosion resistance suitable for general industrial, plumbing, and mechanical applications. The high collar design provides increased contact height compared to standard split lock washers, improving bite and vibration resistance under load. Inside diameter runs 5.1 to 5.4 mm with a maximum outside diameter of 8.8 mm and a thickness of 1.6 mm. The bright uncoated finish is left as-manufactured with no additional coating. This washer conforms to DIN 7980 dimensional standards and is sold in a minimum order quantity of 100 pieces per order.

This washer is used wherever M5 machine screws or bolts require a locking element to resist loosening from vibration or thermal cycling. Typical applications include equipment panels, control enclosures, pump assemblies, and light structural fastening in residential and commercial mechanical systems. The stainless steel construction makes it appropriate for damp or corrosive environments such as plumbing chases, outdoor electrical enclosures, and pool equipment installations where carbon steel hardware would corrode prematurely.

Key Features

• High collar split lock design provides greater axial contact than standard split washers
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance in wet or chemically active environments
• Conforms to DIN 7980 metric fastener standard
• Bright uncoated finish — no risk of coating delamination interfering with clamp load
• Inside diameter range of 5.1 to 5.4 mm ensures proper fit on M5 fasteners
• Minimum order quantity of 100 pieces supports service van stocking and job-lot purchasing

Compatibility

Designed for use with M5 metric screws and bolts. Fits fastener shank diameters consistent with DIN 7980 M5 specifications, with an inside diameter of 5.1 to 5.4 mm.

Installation Notes

Install by placing the washer on the fastener shank before threading into the mating material, with the split gap oriented so the sharp edges contact both the fastener head and the mating surface. Power down or de-energize any equipment before accessing fasteners inside control enclosures or electrical panels, in compliance with applicable NEC lockout-tagout procedures. Do not reuse split lock washers that have been fully compressed flat, as they will not provide effective locking action after deformation. Use appropriate metric hand tools to avoid fastener and washer damage during installation.
