Value Collection 744161PS M22 Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION 744161PS is a Grade 8 metric split lock washer designed for use with M22 fasteners in high-load bolted assemblies. Made from spring steel with a bright, uncoated finish, this washer delivers reliable tension retention under vibration and dynamic loading. It measures 22.5 millimeters minimum inside diameter, up to 23.5 millimeters maximum inside diameter, 35.9 millimeters outside diameter, and 4 millimeters thick. Hardness is rated 44-51 HRC, meeting Grade 8 material requirements per DIN 127. Installation is performed by mechanical assemblers and maintenance technicians working in industrial, structural, or heavy equipment applications.

This split lock washer is suited for industrial bolted connections where M22 fasteners are used and vibration or cyclical loading may cause loosening over time. The helical split design bites into the bearing surface and fastener to resist rotation under load. The uncoated bright finish is appropriate for dry indoor environments or assemblies where additional corrosion protection is applied separately at the system level.

Key Features

• Grade 8 spring steel construction with 44-51 HRC hardness rating
• Helical split design provides mechanical resistance to fastener loosening under vibration
• Inside diameter range of 22.5 to 23.5 millimeters for M22 screw compatibility
• 35.9 millimeters outside diameter, 4 millimeters thick
• Bright, uncoated finish - no coating buildup that could affect torque values
• Conforms to DIN 127 fastener standard, metric system of measurement

Compatibility

Designed for use with M22 metric fasteners in assemblies requiring DIN 127 split lock washers. Verify bearing surface and fastener grade compatibility before installation. Does not meet military specifications.

Installation Notes

This washer is installed by mechanical assemblers, maintenance technicians, or millwrights working on bolted connections. Place the washer between the nut or bolt head and the bearing surface before final torque is applied. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide effective locking force. Consult applicable industry standards or equipment manufacturer specifications for proper fastener torque values.
