Professional Applications & Engineering Value
This zinc-plated brass thumb nut is engineered to address common assembly challenges in electronics, machinery, and instrumentation. The flanged design increases bearing surface area, preventing damage to soft materials and maintaining clamp force under dynamic loads. Its knurled round head enables rapid hand-tightening where tool access is limited, ideal for maintenance panels, adjustable components, and prototype builds. The 8-32 UNC coarse thread with Class 2B fit ensures compatibility with standard threaded rods and inserts, reducing cross-threading risks and streamlining production. Made from brass with zinc plating, it resists oxidation in moist environments, extending service life in HVAC, automotive, and electrical enclosures.
Specification Summary & Compliance
This thumb nut features a 3/8" collar diameter, 7/16" head diameter, and 9/32" height with fully threaded right-hand UNC coarse threads. It maintains Class 2B thread fit per ASME B1.1 standards for consistent engagement. The product is RoHS 3 (2015/863/EU) compliant under exemption 6(b)-II and REACH (EC 1907/2006) compliant, meeting stringent industrial safety and environmental regulations.
