Overview

The Minerallac Company 40544J is a pack of 100 split lock washers, essential for securing fasteners in Grade 5 and Grade 8 applications. These 5/8" medium-sized washers are constructed from thru-hardened steel, ensuring consistent hardness and strength across the entire washer for reliable performance under high-stress conditions. The yellow zinc CR+6 plating provides robust corrosion resistance, meeting the requirements of ASTM B633 Type II SC1 for enhanced durability in outdoor, marine, or industrial environments where moisture, humidity, or mild chemical exposure is present. Each jar contains 100 washers, with 600 units per master carton, allowing for efficient inventory management and bulk purchasing for large-scale projects. The split design creates a spring action that maintains tension on fasteners, preventing loosening due to vibration, thermal cycling, or dynamic loads common in electrical installations, mechanical assemblies, and construction applications. These washers are engineered to work with standard 5/8" bolts and screws, ensuring compatibility with common hardware sizes used in structural, plumbing, and electrical conduit systems. The thru-hardened steel construction delivers superior shear strength and resistance to deformation, making them ideal for critical applications where fastener integrity is paramount. Minerallac’s precision manufacturing ensures consistent dimensions and performance, reducing the risk of premature failure in high-torque or high-vibration scenarios. The yellow zinc CR+6 finish also provides a clear visual indicator of the washer’s corrosion-resistant properties, simplifying identification in inventory and on job sites. Whether used in electrical panel assemblies, machinery mounting, or structural connections, these washers offer a dependable locking solution that meets or exceeds industry standards for medium-duty fastening applications.
