Value Collection 67497040 M8 Metric Split Lock Washer

Product Description

The VALUE COLLECTION 67497040 is a metric split lock washer designed to resist fastener loosening under vibration and dynamic load conditions. Sized for M8 screws, it features an inside diameter of 8.1 to 8.5mm (approximately 0.319 to 0.335 inches), a maximum outside diameter of 14.8mm (approximately 0.583 inches), and a thickness of 2mm (approximately 0.079 inches). The washer is made from uncoated steel and conforms to DIN 127B as well as ASME, ANSI, BS, JIS, and NFE standards. It is sold individually with a minimum order quantity of 100 units, making it suited for production runs, maintenance stock, or bulk fastener assemblies.

This split lock washer is used in general mechanical assembly, HVAC equipment mounting, electrical panel and enclosure fastening, plumbing fixture installation, and light structural applications wherever an M8 fastener requires added resistance to loosening. The spring-action split design bites into both the fastener and mating surface when the fastener is torqued down, maintaining clamp load over time. It is appropriate for both residential and commercial trade work in any application calling for a DIN 127B metric lock washer.

Key Features

• DIN 127B spring lock washer configuration for vibration-resistant fastening
• Inside diameter range of 8.1 to 8.5mm to fit M8 metric screws and bolts
• Maximum outside diameter of 14.8mm for standard M8 bearing surface coverage
• 2mm thickness provides consistent spring action and bite depth
• Uncoated steel construction suitable for general indoor and protected assemblies
• Meets ASME, ANSI, BS, DIN, JIS, and NFE standards for broad application compliance

Compatibility

Designed as a standard DIN 127B metric split lock washer for use with M8 screws and bolts across general mechanical, HVAC, plumbing, and electrical assembly applications.

Installation Notes

Install between the fastener head or nut and the mating surface with the split ends oriented to bite into both surfaces as the fastener is torqued. Verify the mating surface and fastener are clean and free of debris before assembly. For uncoated steel washers, avoid prolonged exposure to moisture or corrosive environments where surface oxidation would be a concern. Minimum order quantity of 100 units applies to procurement of this part number.
