Stainless Steel Split Lock Washer by Hillman 3/8-Inch 100 pcs Pack

Description

Product Overview

The Hillman 830670 split lock washer is engineered from premium stainless steel, offering an ultra‑corrosion‑resistant finish that stands up to harsh environments and repeated exposure to moisture. With an outside diameter of 0.38 inches and a thickness of 0.35 inches, these washers are precisely sized for a 3/8‑inch fastener, ensuring a snug fit that maximizes torque transfer while preventing slippage. The split design creates a spring‑like action that maintains constant pressure on the nut or bolt, distributing load evenly across the joint and reducing the risk of fatigue failure. Each washer is brushed for a smooth surface that resists snagging during installation, and the pack of 100 provides ample inventory for large projects or ongoing maintenance needs.

Usage

These split lock washers excel in a wide range of applications where vibration and corrosion are concerns. In woodworking, they secure cabinet hinges, drawer slides, and structural frames, delivering a quiet, vibration‑free connection that prolongs the life of the assembly. In metalworking, they are ideal for machinery, automotive brackets, and outdoor equipment, where the stainless steel composition combats rust and the split lock action prevents fasteners from loosening under dynamic loads. The washers are also suitable for electrical enclosures, HVAC systems, and marine installations, providing a reliable seal against moisture ingress while maintaining the integrity of the fastening system.

Installation is straightforward: place the washer between the nut and the workpiece, then tighten the fastener to the recommended torque. The split lock washer will automatically adjust to the tightening force, creating a resilient lock that remains effective even after repeated cycles of vibration. Whether you are a professional contractor, a maintenance technician, or a DIY enthusiast, these washers deliver consistent performance across diverse projects.
