Value Collection 67497123 M12 Split Lock Washer Steel Din 127B

Product Description

The VALUE COLLECTION 67497123 is a metric split lock washer designed for use with M12 fasteners in general mechanical assembly applications. Manufactured from steel with a bright uncoated finish, this spring lock washer applies axial tension against a fastener to resist loosening caused by vibration or dynamic load. The inside diameter ranges from 12.2 to 12.7mm, the maximum outside diameter is 21.1mm, and the washer thickness is 2.5mm. It conforms to DIN 127B and meets ASME, ANSI, BS, JIS, and NFE standards. Licensed tradespeople and maintenance technicians in HVAC, plumbing, electrical, and mechanical service use this type of hardware in equipment assembly and structural fastening tasks.

This split lock washer is suited for metric fastening applications requiring a reliable, standards-compliant locking element. It is appropriate for use in residential and commercial mechanical systems where M12 bolts or screws are specified and vibration resistance is required. The bright uncoated steel construction makes it compatible with dry and low-moisture indoor environments. This washer is sold individually per package with a minimum order quantity of 100 pieces, making it practical for shop stock and job-lot procurement.

Compatibility

Designed as a DIN 127B metric split lock washer for use with M12 screws and bolts in general mechanical assembly applications where a standards-compliant spring lock element is specified.

Installation Notes

Installation is performed by placing the washer over the fastener shank and against the bearing surface before running the nut or bolt down. Ensure the fastener thread engagement and torque values comply with the applicable assembly specification or equipment service manual. De-energize or shut down any equipment before performing fastener service on mechanical assemblies. Do not reuse compressed or fully flattened lock washers, as spring tension is not recoverable once the washer is fully seated.
