Value Collection 93803 Lock Washer 8 Screw Stainless Steel 100pk

Product Description

The VALUE COLLECTION 93803 is a No. 8 screw-size external tooth lock washer manufactured from Grade 410 stainless steel. The external tooth design bites into mating surfaces under torque, resisting loosening from vibration and thermal cycling. With an inside diameter of 0.176 inches, an outside diameter of 0.381 inches, and a thickness of 0.023 inches, this washer is sized for standard No. 8 fastener applications. Grade 410 stainless steel provides corrosion resistance and hardness suitable for mechanical and light industrial assembly. This package contains 100 washers, making it practical for production or service shop inventory.

External tooth lock washers of this size are commonly used in HVAC panel assembly, electrical enclosure work, plumbing fixture mounting, and general mechanical assembly where vibration or repeated thermal movement could back out a fastener. They are appropriate for both residential and light commercial applications wherever a No. 8 screw is used against a metal substrate. Licensed technicians and trades workers use these washers during equipment installation, panel work, and component replacement tasks.

Installation Notes

Install with the teeth facing the fastener head or nut, not the substrate, to allow the serrations to embed and lock under tightening load. Power down any electrical panel or equipment before accessing fastened components. Use standard hand tools appropriate to the fastener being driven. Follow applicable NEC, IPC, or IFGC guidelines for the specific trade application.
