Professional Applications & Engineering Value

This black-oxide steel thumb screw addresses critical assembly challenges where tool-free access and repeated adjustments are required. The knurled head delivers maximum torque application by hand, reducing slippage in high-vibration settings like machinery panels, electronic enclosures, and prototyping fixtures. Its 10-24 UNC coarse thread cuts installation time while the extended tip self-centers into components, preventing damage to delicate threads. Ideal for maintenance-heavy environments, the partially threaded design concentrates grip strength where needed, making it a versatile solution for industrial equipment, telecom racks, and automotive assemblies demanding reliable manual fastening.

Specification Summary & Compliance

Manufactured to UNC thread standards with Class 2A thread fit for consistent interchangeability. The black-oxide finish on steel provides corrosion resistance, while construction adheres to RoHS 3 (2015/863/EU) compliance under exemption 6(a)-I for lead as a steel alloying element. Dimensions include 2" length, 3/4" head diameter, and 1 5/8" threaded portion with right-hand orientation.
