1 Inch Split Lock Washer by EASTLO 304 Stainless Steel 10-Pack

Description

Product Overview

The 1 Inch Split Lock Washer by EASTLO is engineered for precision and durability in demanding fastening applications. Constructed from premium 304 stainless steel, each washer offers exceptional corrosion resistance, making it ideal for environments where moisture, chemicals, or extreme temperatures are present. The bright finish not only provides an attractive silver tone but also enhances visibility during installation, reducing the chance of misplacement on the workbench. With an inside diameter of 1.024 inches, an outside diameter of 1.656 inches, and a thickness of 0.25 inches, these washers are perfectly sized for 1″ screws, delivering a secure, vibration‑resistant lock that maintains tension over time.

The split‑lock design features a small gap that allows the washer to flex and grip the screw head or nut, preventing loosening caused by vibration or dynamic loads. This mechanical advantage eliminates the need for additional locking compounds, simplifying assembly and reducing maintenance costs. Each package contains ten washers, providing ample supply for multiple projects while ensuring consistent performance across each unit. The compact packaging dimensions of 4.76 x 4.57 x 1.01 inches and a lightweight 14.22‑ounce total weight make storage and handling effortless for both professional technicians and DIY enthusiasts.

Usage

These split lock washers excel in a wide range of industrial and commercial settings. In machinery assembly, they secure motor housings, gearboxes, and pump components, where constant vibration could otherwise lead to fastener fatigue. Automotive technicians rely on them for brake system installations, engine mounts, and chassis reinforcement, where safety and reliability are paramount. Outdoor equipment manufacturers use the washers in weather‑exposed applications such as marine hardware, agricultural machinery, and construction tools, benefiting from the stainless steel’s resistance to rust and corrosion.

The washers are also suitable for electrical enclosures, HVAC systems, and lighting fixtures, where they help maintain tight connections despite thermal expansion and contraction. Their bright finish aids in quick visual inspection, ensuring that the correct component is installed without the need for additional marking or labeling. Whether you are assembling a high‑performance racing component, maintaining industrial equipment, or completing a home improvement project, these washers provide the confidence that your fasteners will stay locked in place.
