Value Collection 744181PS M27 Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION 744181PS is an M27 metric split lock washer manufactured from Grade 8 spring steel with a bright uncoated finish. Designed to resist fastener loosening under vibration and dynamic load, the split lock washer works by biting into the bearing surface and the underside of the nut or bolt head as the fastener is tightened. With a 27.5mm minimum inside diameter, a 43mm outside diameter, and a 5mm thickness, this washer meets DIN 127 dimensional standards. Hardness is rated at 44 to 51 HRC, providing the spring tension needed for reliable locking performance in demanding applications.

This washer is suited for general industrial, mechanical, and structural assembly work where metric M27 fasteners are used. It is commonly installed in machinery, heavy equipment, fabrication, and plant maintenance environments. The uncoated finish makes it appropriate for use where additional coatings or treatments will be applied downstream, or where bare steel is acceptable. Sold individually per package with a minimum order quantity of 25 pieces.

Installation Notes

Split lock washers are installed by mechanics and maintenance technicians using standard hand or power tools. Place the washer between the fastener bearing surface and the nut or bolt head before tightening. Do not reuse a split lock washer that has been fully compressed flat, as spring tension will be lost. Torque fasteners per the applicable assembly specification for the joint being serviced.
