Value Collection 93829 Internal Tooth Lock Washer 7/16 Stainless

Product Description

The VALUE COLLECTION 93829 is a stainless steel internal tooth lock washer designed for use with 7/16 inch screws and fasteners. The serrated internal teeth bite into the mating surface and fastener head during torque application, resisting loosening caused by vibration and dynamic loads. Manufactured from Grade 410 stainless steel, this washer offers corrosion resistance suitable for demanding environments. With an inside diameter of 0.464 inches and an outside diameter of 0.789 inches, it is sized for standard 7/16 inch fastener applications. This item is sold in a pack of 100 and is installed by electricians, HVAC technicians, plumbers, and mechanical contractors as part of routine fastener assemblies.

Internal tooth lock washers in this size range are widely used in residential and light commercial mechanical, electrical, and HVAC installations wherever vibration-resistant fastening is required. Common applications include equipment panel assembly, conduit fitting securement, and mechanical equipment mounting. The Grade 410 stainless steel construction makes these washers appropriate for environments where mild to moderate corrosion resistance is needed alongside reliable locking performance. Packs of 100 suit service vehicles and shop stock for high-frequency fastener work.

Compatibility

Designed as a standard internal tooth lock washer for use with 7/16 inch screws and bolts in mechanical, electrical, and HVAC fastener assemblies.

Installation Notes

Install with the teeth facing the fastener head or the clamping surface to ensure proper locking engagement. Ensure the mating surface is clean and free of debris before seating the washer. Follow applicable NEC or mechanical code requirements for fastener assemblies in electrical and HVAC applications. Do not reuse lock washers after full torque has been applied, as tooth deformation reduces locking effectiveness on reinstallation.
