Professional Applications & Engineering Value
This 5/16"-18 UNC thumb screw is engineered to solve common industrial fastening challenges, such as frequent adjustments and misaligned components. The black-oxide steel construction resists corrosion, making it ideal for machinery, electronic enclosures, and outdoor equipment where durability is critical. The permanent swivel tip distributes pressure evenly, preventing marring on sensitive surfaces and accommodating up to 7.5° of angular deviation. Combined with a coarse UNC thread and fully threaded design, it ensures quick, tool-free installation and reliable performance in heavy-duty applications, reducing assembly time and maintenance costs.
Specification Summary & Compliance
This thumb screw adheres to UNC thread standards with a Class 2A thread fit for precise dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability for industrial use.
