Professional Applications & Engineering Value

This 10-32 UNF thumb screw is engineered for applications requiring frequent adjustments and reliable clamping force without specialized tools. The black-oxide steel construction offers excellent resistance to rust and wear, making it ideal for electronics enclosures, machinery panels, and assembly jigs where exposure to oils or moisture is common. The low-profile, knurled head delivers superior tactile feedback and slip resistance, reducing operator fatigue and preventing damage to sensitive components. With its fine thread spacing and Class 2A thread fit, it ensures vibration-resistant fastening in precision equipment, while the fully threaded design maximizes load distribution. This screw solves common industrial pain points by combining manual convenience with the mechanical integrity needed for high-performance industrial thumb screw applications.

Specification Summary & Compliance

This thumb screw adheres to UNF thread standards with a Class 2A thread fit for consistent dimensional accuracy. It meets RoHS 3 (2015/863/EU) compliance under exemption 6(a)-I and is REACH (EC 1907/2006) compliant, ensuring it is free from hazardous substances as per the latest regulations. Manufacturing specifications include a tensile strength of 70,000 psi and a hardness of Rockwell B84, confirming its reliability for industrial fastening tasks.
