Value Collection 742086PS M6 Internal Tooth Lock Washer

Product Description

The VALUE COLLECTION 742086PS is an M6 internal tooth lock washer designed to maintain fastener tension and prevent loosening under vibration. The washer features inward-facing teeth that bite into the mating surface and fastener head, creating a positive locking action. It is manufactured from Grade 2 spring steel and finished with a zinc plating for basic corrosion resistance. With an inside diameter of 6.4mm, an outside diameter of 11.0mm, and a thickness of 0.7mm, this washer is sized for use with M6 screws and bolts. Electricians, HVAC technicians, and mechanical contractors use this style of lock washer in panel assemblies, equipment mounting, and general fastener applications.

Internal tooth lock washers in this size range are commonly used in light to medium-duty fastening applications where vibration resistance is required. Typical install scenarios include electrical enclosure assembly, HVAC equipment panel mounting, and mechanical component attachment in residential and light commercial settings. The zinc-plated finish suits indoor and light-duty outdoor use where exposure to moisture is limited. This washer is sold individually, with a minimum order quantity of 200 pieces per order.

Installation Notes

Install between the fastener head or nut and the mating surface with the teeth facing the surface to be engaged. Ensure mating surfaces are clean and free of coatings that would prevent the teeth from seating properly. De-energize and lock out any electrical panel or equipment before servicing fastened assemblies. Follow applicable NEC or equipment manufacturer torque guidelines when tightening M6 fasteners.
