Professional Applications & Engineering Value
These Grade 8 split lock washers deliver exceptional engineering value in demanding industrial environments where vibration-induced fastener failure is a critical concern. The zinc yellow-chromate plated steel construction combines high tensile strength with superior corrosion protection, making them ideal for heavy machinery, construction equipment, and automotive applications. The standard split lock washer design creates continuous spring tension that maintains bolt preload even under severe vibration conditions. With precise dimensions (1.024" ID, 1.656" OD) and Rockwell C38 hardness, these washers provide consistent performance in high-torque applications while preventing damage to mating surfaces. Their robust construction solves the common industrial problem of fastener loosening, reducing maintenance frequency and improving operational safety.
Specification Summary & Compliance
This split lock washer features inch system measurements with 1.024" inner diameter, 1.656" outer diameter, and 0.25" thickness, designed for 1" screw size applications. Manufactured to exacting ASME B18.21.1 specifications, ensuring dimensional precision and performance reliability. The product maintains Grade 8 fastener strength classification and demonstrates full compliance with REACH (EC 1907/2006) regulations regarding substance restrictions, confirming environmental responsibility and regulatory adherence as of June 14, 2023.
