Professional Applications & Engineering Value
This 10-32 UNF thumb screw combines the corrosion-resistant properties of 18-8 stainless steel with the exceptional grip characteristics of a knurled acetal plastic head, creating an optimal solution for frequent adjustment applications in electronics, instrumentation, and machinery. The low-profile design addresses space constraints in compact assemblies while the Class 3A thread fit ensures precise engagement in threaded inserts and mounting plates. The fine UNF threading provides superior vibration resistance compared to coarse threads, making it ideal for precision equipment where maintaining calibration is critical. The combination of materials delivers reliable performance across the specified temperature range without compromising the knurled texture's non-slip properties.
Specification Summary & Compliance
This thumb screw features 10-32 UNF Class 3A threads with fine thread spacing and right-hand direction, manufactured to precise dimensional standards. The fastener is fully threaded with a 3/8" length and 5/8" head diameter. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for industrial applications requiring certified components.
