Description

Product Overview

The Hillman Group 42209 split lock washers are precision‑engineered components designed to deliver consistent, vibration‑resistant fastening in a broad range of mechanical assemblies. Constructed from high‑grade alloy steel, each washer benefits from a robust zinc coating that provides superior corrosion resistance, extending the service life even in harsh, moisture‑laden environments. With an outside diameter of one inch and a thickness of 0.35 inches, these round, split‑type lock washers are sized to fit a 1/2‑inch fastener, making them an ideal match for standard bolts, screws, and studs used across industrial, automotive, and home‑improvement projects. The pack contains 25 individually packaged washers, each weighing approximately 5.3 ounces, allowing for easy inventory management and quick access during assembly or maintenance tasks. Detailed specifications include a metallic finish, a round head style, and compliance with industry standards for spring lock washers, ensuring reliable torque retention and reduced loosening under dynamic loads. Whether you are building a machine, repairing equipment, or completing a DIY furniture project, these split lock washers provide the necessary grip and durability to keep connections secure over time.

Usage

These split lock washers excel in applications where vibration, thermal cycling, or repetitive motion could cause traditional flat washers to shift or loosen. In industrial settings, they are commonly employed on machinery frames, conveyor systems, and pump assemblies to maintain bolt tension and prevent costly downtime. For automotive enthusiasts, the washers are suitable for securing engine components, suspension brackets, and exhaust mounts, where consistent clamping force is critical for safety and performance. Home‑improvement professionals also rely on these washers for outdoor decking, fence construction, and garden equipment, benefiting from the zinc coating’s resistance to rust caused by exposure to rain and soil. The 25‑piece quantity ensures that users have enough washers on hand for multiple installations, bulk repairs, or large‑scale projects without the need for frequent reordering. Their split design allows for easy installation with standard wrenches or socket sets, and the round shape provides uniform load distribution across the fastener head, reducing the risk of material deformation or surface damage.
