• Time-saving installation using right-hand threading that follows conventional tightening direction

Professional Applications & Engineering Value

This 316 stainless steel thumb nut solves critical challenges in maintenance-heavy and corrosive environments. Its corrosion-resistant material withstands exposure to chemicals, moisture, and extreme temperatures, preventing thread seizure and extending service life in marine, food processing, and pharmaceutical applications. The coarse UNC thread and Class 2B fit ensure rapid alignment and robust clamping force on shafts, fixtures, and adjustment points—eliminating cross-threading risks while supporting high vibration loads. The 2" wing span provides ample torque leverage for personnel to secure connections firmly by hand, reducing dependency on tools in confined spaces or during rapid prototyping. This combination of durable construction and user-centered design makes it ideal for access panels, fluid control systems, and temporary jigs where frequent adjustments are necessary.

Specification Summary & Compliance

Manufactured to precise Class 2B thread tolerances for consistent fit with UNC 7/16"-14 fasteners. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory standards, ensuring restriction of hazardous substances. Right-hand coarse thread spacing provides optimal engagement for general-purpose industrial applications. Base diameter measures 21/32" with overall dimensions of 2" width and 1" height for standardized compatibility.
