Value Collection 361450PS M45 Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION 361450PS is a metric split lock washer designed for M45 fastener applications. Made from Grade 8 spring steel with a zinc plated finish, it provides resistance to loosening under vibration and dynamic load by biting into the mating surface when torque is applied. The washer conforms to DIN 127 fastener standards and carries a hardness rating of 44 to 51 HRC, making it suitable for high-load bolted assemblies. With a minimum inside diameter of 45.5mm, a maximum outside diameter of 71.2mm, and a thickness of 7mm, this washer is sized for heavy-duty M45 fastener installations across industrial and mechanical applications.

This split lock washer is intended for use in bolted joint assemblies requiring reliable anti-loosening performance under vibration, shock, or cyclic loading. Typical applications include heavy industrial machinery, structural steel connections, and large mechanical assemblies where M45 fasteners are specified. It is installed by machinists, millwrights, and maintenance technicians working with metric fastener systems. The zinc plated finish provides a basic level of corrosion resistance suitable for indoor and protected outdoor environments. This item is sold individually with a minimum order quantity of 5 pieces.

Key Features

• Grade 8 spring steel construction delivers high hardness and reliable spring tension under load
• Hardness of 44 to 51 HRC resists deformation during installation and service
• Zinc plated finish provides basic corrosion protection for general-use environments
• Conforms to DIN 127 fastener standard for consistent metric dimensional compliance
• Inside diameter range of 45.5 to 46.7mm ensures proper fitment on M45 fasteners
• 7mm thickness supports load distribution across the bearing surface

Compatibility

Designed for use with M45 metric fasteners in bolted assemblies conforming to DIN 127 split lock washer specifications.

Installation Notes

Installed by machinists, millwrights, or maintenance technicians as part of a standard bolted joint assembly. Place the split lock washer between the nut or bolt head and the mating surface before final torquing. Ensure mating surfaces are clean and free of debris to allow proper seating and spring action. Follow applicable torque specifications for M45 fasteners as defined by the relevant industry standard or engineering requirement.
