Value Collection 30125694 M10 Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION 30125694 is a metric split lock washer designed for M10 fastener assemblies where vibration resistance and joint integrity are critical. Manufactured from Grade 8 spring steel with a zinc plated finish, this washer delivers a hardness rating of 44 to 51 HRC, providing the tension and bite necessary to resist loosening under dynamic loads. With an inside diameter of 10.2 to 10.7mm and a maximum outside diameter of 18.1mm, it installs directly beneath an M10 nut or bolt head. Thickness is 2.2mm. It is a standard component in mechanical, structural, and industrial fastener assemblies across a wide range of trade applications.

This split lock washer is suited for use in residential and commercial mechanical assemblies where metric fasteners are specified. Typical applications include HVAC equipment mounting, electrical panel and enclosure hardware, plumbing support structures, and general equipment installation where M10 fasteners are used. The zinc plated finish provides basic corrosion resistance in mildly exposed environments. This product meets ASME, ANSI, BS, DIN, JIS, and NFE standards and conforms to DIN 127. It is sold individually per package with a minimum order quantity of 100 pieces.

Key Features

• Grade 8 spring steel construction with 44 to 51 HRC hardness for reliable locking tension
• Zinc plated finish for basic corrosion resistance in standard service environments
• Conforms to DIN 127 fastener standard; meets ASME, ANSI, BS, DIN, JIS, and NFE specifications
• Inside diameter of 10.2 to 10.7mm fits M10 fastener assemblies
• 2.2mm thickness provides consistent split-lock engagement
• Metric dimensioning throughout for use in metric-specified assemblies

Compatibility

Designed for use with M10 screws, bolts, and nuts in metric fastener assemblies conforming to DIN 127 and related ASME, ANSI, BS, DIN, JIS, and NFE standards.

Installation Notes

Split lock washers are installed by placing the washer on the fastener shank between the nut or bolt head and the mating surface before torquing. Ensure the assembly is de-energized and, where applicable, depressurized before servicing any fastened joint. Do not reuse lock washers that have been fully compressed flat, as they will no longer provide effective locking tension. Installation should comply with applicable mechanical and structural codes for the specific trade and application.
