Value Collection 744020PS M2 Split Lock Washer Spring Steel

Product Description

The VALUE COLLECTION 744020PS is an M2 metric split lock washer manufactured from spring steel and supplied in its natural bright, uncoated finish. Designed to resist loosening under vibration and dynamic loads, split lock washers work by biting into the mating surface and fastener head when the assembly is tightened. This washer carries a hardness rating of 44-51 HRC, giving it the strength needed to maintain clamp load in demanding mechanical assemblies. It conforms to DIN 127 dimensional standards and is sized for M2 screws, making it a standard choice for precision fastener assemblies in light mechanical, electrical, and instrumentation work.

This washer is suited for metric fastener assemblies requiring a low-profile locking element at the M2 screw size. Typical applications include small-frame electrical enclosures, PCB mounting hardware, instrument panels, and other assemblies where vibration resistance is needed without the bulk of a larger locking element. The uncoated bright finish is appropriate for indoor and controlled-environment applications. This SKU is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• DIN 127 compliant metric split lock washer for M2 screw size
• Spring steel construction with 44-51 HRC hardness for reliable clamp retention
• Bright, uncoated finish suitable for indoor and controlled-environment use
• Inside diameter range of 2.1 to 2.4mm accommodates standard M2 fastener shank tolerances
• 0.5mm thickness provides a low-profile locking solution in tight assemblies
• Minimum order quantity of 100 pieces per transaction

Compatibility

Designed for use with M2 metric screws and bolts in assemblies conforming to DIN 127 fastener standards. Suitable for metric fastener applications requiring a split lock washer at the M2 size class.

Installation Notes

Install between the fastener head and the mating surface or flat washer, with the split gap positioned to allow the washer to bite into both surfaces as the fastener is torqued down. Ensure mating surfaces are clean and free of debris before assembly. For electrical or instrumentation applications, follow applicable equipment manufacturer guidelines and any governing codes for hardware installation. Do not reuse split lock washers after disassembly, as the spring tension may be compromised.
