Professional Applications & Engineering Value
These zinc-plated steel thumb screws deliver exceptional value in applications requiring frequent adjustments or rapid assembly/disassembly cycles. The spade head design eliminates tool dependency while providing substantial torque transmission for secure fastening. Engineered with UNC coarse threads and Class 2A tolerance, they offer reliable performance in vibration-prone environments where fine threads might loosen. The combination of Rockwell B55 hardness and 40,000 psi tensile strength ensures these thumb screw fasteners maintain structural integrity under repeated use in industrial equipment, electrical enclosures, machinery guards, and prototyping fixtures. The fully threaded 1" length accommodates various material thicknesses while the right-hand thread direction follows industry standards for intuitive operation.
Specification Summary & Compliance
This 5/16"-18 thumb screw features precision UNC coarse threads manufactured to Class 2A dimensional standards, ensuring consistent fit and reliable performance. The fastener meets RoHS 3 (2015/863/EU) compliance requirements, confirming adherence to environmental regulations for hazardous substance restrictions. Manufacturing specifications include right-hand thread direction, fully threaded design, and standardized spade head configuration with 7/8" width and 11/16" height dimensions.
