Professional Applications & Engineering Value
This zinc-plated steel thumb screw delivers exceptional value in applications requiring frequent access or adjustment, such as electrical enclosures, machinery guards, and production jigs. The 6-32 UNC coarse threading enables rapid installation while the spade head design eliminates tool dependency in maintenance scenarios. Engineered with Rockwell B55 hardness, the screw maintains dimensional stability through repeated use, preventing thread deformation that compromises fastening integrity. The fully threaded configuration ensures maximum grip length while the right-hand thread direction provides intuitive operation for technicians. Ideal for industrial equipment, electronic assemblies, and manufacturing fixtures where reliable, tool-free fastening solutions are essential for operational efficiency.
Specification Summary & Compliance
This thumb screw features precision Class 2A thread fit per UNC standards with 6-32 thread size and coarse thread spacing. Manufacturing complies with RoHS 3 (2015/863/EU) environmental regulations, ensuring restriction of hazardous substances. The fastener maintains dimensional accuracy with 1/2" length, 1/4" head height, and 3/8" head width for consistent performance across applications.
