Professional Applications & Engineering Value

Engineered for industrial applications requiring frequent adjustments and reliable fastening, this 10-32 UNF thumb screw combines the corrosion resistance of 18-8 stainless steel with practical user benefits. The knurled round head provides exceptional grip for hand-tightening in maintenance panels, electronic enclosures, and machinery guards where tools are impractical. Its low-profile design prevents snagging in compact assemblies while the fine UNF threads maintain secure positioning in vibration-prone environments. The partial threading allows for controlled clamping force on components ranging from 1/8" to 1/2" thickness, making it ideal for precision equipment, aerospace fixtures, and medical device manufacturing where repeated access and corrosion resistance are critical.

Specification Summary & Compliance

Manufactured to precise inch system measurements with Class 2A thread fit tolerance per UNF standards. The screw features a 10-32 thread size with right-hand direction and 1 15/16" thread length on a 2" overall shank. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for international industrial supply chains.
