Value Collection 361040PR M5 Split Lock Washer Spring Steel

Product Description

The VALUE COLLECTION 361040PR is a metric split lock washer designed to resist fastener loosening under vibration and dynamic loads. Made from Grade 8 spring steel with a zinc-plated finish, this washer seats under an M5 screw or bolt head and bites into the mating surface when the fastener is torqued, creating mechanical resistance against rotation. Inside diameter ranges from 5.1 to 5.4mm, outside diameter is 9.2mm, and thickness is 1.2mm. Hardness is rated at 44 to 51 HRC, consistent with DIN 127 standards. Electricians, HVAC technicians, plumbers, and general mechanical trades use these in panel assemblies, equipment mounting, and piping support hardware.

This split lock washer is suited for metric M5 fastener applications in both residential and light commercial settings. Typical uses include securing electrical enclosure hardware, HVAC component brackets, pump mounting bolts, and other assemblies where vibration or thermal cycling could cause fastener loosening over time. The zinc-plated finish provides basic corrosion resistance for indoor and protected outdoor installations. Sold individually, with a minimum order quantity of 100 pieces.

Key Features

• Grade 8 spring steel construction with 44 to 51 HRC hardness for consistent clamp load retention
• Zinc-plated finish for basic corrosion resistance in typical indoor and protected environments
• Conforms to DIN 127 fastener standard for metric split lock washers
• Inside diameter range of 5.1 to 5.4mm accommodates standard M5 fastener shanks
• 1.2mm thickness provides reliable spring action under load

Compatibility

Designed for use with M5 metric screws and bolts. Fits standard M5 fastener applications conforming to DIN 127 metric split lock washer specifications.

Installation Notes

Installation is performed by any trade professional working with metric fastener assemblies. Place the split lock washer between the fastener head and the mating surface before driving the fastener. Do not reuse split lock washers that have been fully compressed flat, as spring action will not be restored. Ensure mating surfaces are clean and free of debris to achieve proper seating and clamp load.
