Value Collection LWIS0-81USA-100BX No. 8 Split Lock Washer

Product Description

The VALUE COLLECTION LWIS0-81USA-100BX is a No. 8 split lock washer manufactured from Grade 2 spring steel with a yellow zinc dichromate finish. Split lock washers apply spring tension under a fastener head or nut to resist loosening caused by vibration and torque relaxation. The inside diameter ranges from 0.167 to 0.174 inches, the maximum outside diameter is 0.293 inches, and the washer thickness is 0.04 inches. This box contains 100 washers and is suited for general mechanical assembly work across multiple trades and industries where vibration resistance is required.

These split lock washers are used in light structural, mechanical, and electrical assembly applications calling for a No. 8 screw. Typical installation scenarios include equipment panels, junction boxes, HVAC components, and general hardware assemblies where fastener retention under vibration is a concern. The yellow zinc dichromate finish provides moderate corrosion resistance suitable for indoor and light-duty outdoor applications. The inch measurement system makes these washers straightforward to specify alongside standard fractional and numbered fastener hardware.

Key Features

• Grade 2 spring steel construction delivers reliable elastic tension under load
• Yellow zinc dichromate finish provides moderate corrosion resistance
• Inside diameter of 0.167 to 0.174 inches fits No. 8 screws
• Maximum outside diameter of 0.293 inches and thickness of 0.04 inches conform to standard split lock washer geometry
• Box quantity of 100 supports production and service-call volume needs
• Does not meet military specifications — intended for commercial and general-trade use

Compatibility

Designed for use with No. 8 machine screws and equivalent fasteners in the inch measurement system across general mechanical, electrical, and HVAC assembly applications.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before final torque is applied. Power down or de-energize any equipment before performing fastener service on electrical or HVAC assemblies. Use standard hand tools; do not compress the washer fully flat during installation, as loss of spring tension eliminates locking action. Follow applicable codes such as the NEC for electrical panel fastening or equipment manufacturer specifications for torque requirements.
