Split Lock Washer 1/2-Inch Grade 8 by Hillman 50-Pack Dichromate

Description

Product Overview

The Hillman Group 300315 split lock washer is engineered for demanding industrial and DIY applications. Constructed from high‑grade alloy steel, each washer receives a zinc yellow‑chromate coating that enhances corrosion resistance while maintaining a bright, identifiable finish. The 1/2‑inch inner diameter and 0.35‑inch thickness provide a robust interface for standard 1/2″ bolts and screws, delivering consistent tension across a wide range of fastener sizes. With a 50‑piece pack, users receive ample supply for bulk projects, maintenance kits, or inventory stocking.

Usage

These split lock washers excel in wood construction, cabinetry, and furniture assembly where vibration and cyclic loading are common. The spring‑type split design allows the washer to flex under load, maintaining pressure on the fastener head and preventing loosening over time. They are also suitable for metal‑to‑metal connections in light machinery, automotive brackets, and electrical enclosures where a reliable, non‑slipping joint is essential. The zinc‑yellow finish makes them easy to spot in mixed‑hardware bins, reducing selection errors on the shop floor.
