Value Collection 86853249 Split Lock Washer 7/16 in Grade 8 25pk

Product Description

The VALUE COLLECTION 86853249 is a Grade 8 alloy steel split lock washer sized for 7/16-inch fasteners. Split lock washers are used under bolt heads or nuts to resist loosening caused by vibration and torque load. The washer's split profile bites into the mating surface when the fastener is tightened, creating a mechanical lock. With a zinc plated finish, this washer resists light corrosion in typical indoor and sheltered outdoor environments. At 0.109 inches thick and an inside diameter range of 0.440 to 0.450 inches, it is dimensioned to seat correctly on a standard 7/16-inch fastener shank. Sold in a pack of 25, it suits both single-job use and small-inventory stocking.

Grade 8 alloy steel split lock washers are used across a wide range of trade and industrial applications where high-strength fastening is required. Common installation scenarios include structural equipment mounting, HVAC unit base rails, electrical panel and equipment anchoring, and mechanical assemblies subject to vibration. The Grade 8 material grade indicates a high-tensile alloy steel, making this washer appropriate for use with Grade 8 bolts and high-load fastener assemblies. This washer is sold in a 25-piece package, suitable for service vans, job-site kits, or shop stock.

Installation Notes

Install split lock washers between the fastener head or nut and the mating surface before final torque is applied. Ensure the fastener grade matches or exceeds the washer grade to maintain assembly integrity. De-energize or shut down any equipment before performing fastener work on electrical, HVAC, or mechanical systems. Follow applicable codes and equipment manufacturer torque guidelines for the specific fastener assembly.
