Professional Applications & Engineering Value
This 6-32 UNC thumb screw in 18-8 stainless steel delivers critical performance advantages for industrial assembly and maintenance applications. The knurled head texture provides exceptional grip even when wearing gloves, significantly reducing installation time while preventing hand fatigue. The coarse UNC threading ensures rapid engagement and disengagement in machinery panels, electronic enclosures, and equipment access points. With its Rockwell B83 hardness and 80,000 psi tensile strength, this fastener maintains structural integrity in vibration-prone environments. The partial threading design offers precise stop control, making it ideal for applications requiring specific depth settings without compromising the Class 2A thread fit precision.
Specification Summary & Compliance
This thumb screw features precise 6-32 UNC coarse threading with Class 2A thread fit tolerance for consistent performance. The 0.138" thread diameter and 9/16" thread length provide optimal engagement characteristics. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring material safety and regulatory adherence for industrial applications worldwide.
