Professional Applications & Engineering Value
This 18-8 stainless steel thumb nut solves critical challenges in maintenance-heavy and corrosion-prone environments. The UNF fine thread configuration with Class 2B thread fit prevents cross-threading during repeated manual installations while maintaining consistent clamping force in vibrating equipment. The 2" wing span provides exceptional leverage for workers wearing gloves, significantly reducing installation time in electrical enclosures, machinery guards, and fluid system panels. Unlike plated fasteners, the solid stainless steel construction maintains its integrity when exposed to chemicals, moisture, and temperature fluctuations, making it ideal for food processing, marine, and outdoor industrial applications where tool access is limited but reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2B thread tolerances for Unified National Fine (UNF) 1/2"-20 right-hand threads. The component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring adherence to international environmental and safety regulations. Physical specifications include 2" width, 1" height, and 29/32" base diameter for consistent performance across compatible mating components.
