Professional Applications & Engineering Value
These 1/4"-20 UNC hanger bolts are engineered to address common challenges in extension spring systems and industrial anchoring, where vibration resistance and long-term durability are critical. The black-oxide steel construction provides a protective layer that minimizes rust and wear, even in humid or high-stress conditions. With coarse thread spacing, the bolts offer enhanced grip and reduced risk of stripping, making them ideal for heavy-duty applications like machinery frames, automotive suspensions, and furniture assembly. The stud anchor design simplifies mounting in pre-drilled holes, while the right-hand thread ensures compatibility with standard tools, streamlining maintenance and reducing downtime.
Specification Summary & Compliance
This product adheres to UNC thread standards with a 1/4"-20 thread size and coarse spacing for reliable performance. The manufacturing process ensures dimensional accuracy, including a consistent 0.15" hole diameter and 7/8" minimum thread length. It is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead in steel alloys and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial and consumer applications.
