Professional Applications & Engineering Value
This cadmium-plated steel split lock washer delivers critical vibration resistance in demanding industrial applications where fastener loosening poses significant operational risks. The split lock washer design creates continuous spring action that compensates for thermal expansion, material relaxation, and dynamic loading conditions. Engineered specifically for No. 4 screw size applications, the 0.114" internal diameter ensures perfect fitment while the cadmium plating provides essential corrosion protection in environments exposed to moisture, chemicals, and temperature variations. These industrial washers are particularly valuable in assembly lines, machinery maintenance, and electronic enclosures where consistent clamping force is paramount to operational safety and equipment longevity.
Specification Summary & Compliance
Manufactured to exacting dimensional standards with 0.114" internal diameter, 0.209" outer diameter, and 0.025" thickness. Features Rockwell C38 hardness for optimal spring performance and meets ASME B18.21.1 and MS35338-40 specifications for material quality, dimensional accuracy, and functional reliability. The cadmium-plated steel construction complies with industry standards for corrosion resistance and mechanical properties in inch system applications.
