Value Collection 361330PS M33 Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION 361330PS is an M33 metric split lock washer designed to resist loosening caused by vibration and dynamic loads in bolted assemblies. Manufactured from Grade 8 spring steel with a zinc plated finish, it delivers a Rockwell hardness of 44 to 51 HRC for reliable bite and spring tension under load. The washer measures 33.5 to 34.7mm inside diameter and 53.2 to 55.2mm outside diameter with a 6mm thickness, and conforms to DIN 127 standards. It is suitable for use by maintenance technicians, millwrights, and mechanical contractors working on heavy-duty fastening applications where hardware integrity is critical.

This split lock washer is used in industrial and commercial mechanical assemblies where M33 fasteners are specified. Typical applications include structural equipment mounting, machine frames, pump and motor bases, and other assemblies subject to vibration or thermal cycling. The zinc plated coating provides a baseline level of corrosion resistance for indoor and light-duty environments. Sold individually with a minimum order quantity of 25 pieces, making it suitable for shop stock or job-lot procurement.

Key Features

• Grade 8 spring steel construction with 44 to 51 HRC hardness for strong spring-back and anti-loosening performance
• Zinc plated finish for corrosion resistance in standard service environments
• Conforms to DIN 127 fastener standard for consistent metric fitment
• M33 screw size with 33.5 to 34.7mm inside diameter and 53.2 to 55.2mm outside diameter
• 6mm thickness provides adequate bearing surface and deflection range for heavy fasteners
• Minimum order quantity of 25 units supports stock replenishment and bulk assembly work

Compatibility

Designed for use with M33 metric fasteners in assemblies conforming to DIN 127 specifications. Suitable for Grade 8 or equivalent metric bolt and nut combinations in industrial and commercial mechanical installations.

Installation Notes

Install between the nut or bolt head and the mating surface with the split gap positioned to bite into both surfaces as the fastener is torqued. Spring steel lock washers should not be reused after removal, as the spring temper may be compromised. Ensure mating surfaces are clean and free of debris before assembly. Installation is typically performed by millwrights, maintenance mechanics, or mechanical contractors using standard hand or power torque tools.
