Professional Applications & Engineering Value
This zinc-plated steel hold-down bolt with its specialized 20° flat hook profile delivers exceptional engineering value in applications requiring secure, permanent anchoring. The partially threaded design with UNC coarse threading maintains structural integrity while allowing for precise tension adjustment in industrial machinery, construction frameworks, and equipment mounting systems. The combination of 60,000 PSI tensile strength and Rockwell B70 hardness ensures reliable performance under sustained loads and vibration, making it ideal for securing heavy equipment, structural components, and transportation systems where failure is not an option. The right-hand thread direction and coarse thread spacing facilitate quick installation in time-sensitive industrial maintenance and assembly operations.
Specification Summary & Compliance
This hold-down bolt features precise Class 2A thread fit tolerance with UNC 5/16"-18 coarse threading and 2-9/16" thread length. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring hazardous substance restriction compliance. The 0.3125" screw diameter and 5-7/8" overall length maintain dimensional accuracy for consistent performance across industrial applications.
