Professional Applications & Engineering Value

This 18-8 stainless steel thumb screw addresses critical industrial challenges where frequent adjustments and reliable fastening are paramount. The knurled head texture ensures maximum grip even in oily conditions or when wearing gloves, while the 10-32 UNF fine threading provides superior vibration resistance compared to coarse threads. The low-profile round head design minimizes protrusion in confined spaces, making it ideal for electronic enclosures, machinery access panels, and instrumentation. The extended tip facilitates easier alignment during installation, reducing assembly time and preventing cross-threading. With its partial threading configuration, this thumb screw offers optimal clamping force distribution for repeated access applications without compromising structural integrity.

Specification Summary & Compliance

Manufactured to precise Class 2A thread fit tolerances with 10-32 UNF fine threading standard, this thumb screw maintains dimensional accuracy across production batches. The 2" overall length with 1 5/8" thread length and 0.125" extended tip ensures consistent performance in various mounting scenarios. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental responsibility and workplace safety standards. The right-hand thread direction follows industry conventions for intuitive operation across maintenance and manufacturing applications.
