Professional Applications & Engineering Value
This 6-32 UNC thumb screw delivers exceptional engineering value where frequent access and tool-free operation are critical. The 18-8 stainless steel construction provides inherent corrosion resistance for electronics enclosures, medical devices, and outdoor equipment exposed to moisture. The fully threaded design with coarse spacing ensures rapid installation in production environments while the knurled head offers positive grip even with gloved hands. The raised round-head profile combined with collar dimensions creates a stable bearing surface that distributes clamping pressure evenly, preventing damage to sensitive components. These features make it ideal for access panels, calibration adjustments, and machinery where repeated maintenance cycles demand durable, reliable fastening solutions.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit standards with UNC coarse thread spacing (6-32 thread size, 0.138" diameter). Features include 3/8" length, 7/16" head diameter, and right-hand threading. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for global industrial applications requiring restricted substance control.
