Professional Applications & Engineering Value

This 8-32 UNC spade thumb screw solves critical manual fastening challenges in industrial and electronic applications where tool access is limited. The 18-8 stainless steel construction provides excellent corrosion resistance for harsh environments, while the flanged spade head (23/64" width, 25/64" height) delivers superior torque transmission and prevents over-tightening. The coarse thread spacing with Class 2A thread fit ensures rapid installation and reliable performance in vibration-prone assemblies, making it ideal for electronic enclosures, machinery panels, and frequent-access components requiring manual fastening solutions without compromising durability or precision.

Specification Summary & Compliance

Manufactured to precise UNC thread standards with Class 2A thread fit for consistent performance. Features 8-32 thread size, 0.164" thread diameter, and 3/8" fully threaded length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The flanged spade head design (0.281" flange diameter) provides additional bearing surface while maintaining dimensional accuracy throughout the fastener.
