S-94775A033 1/2"-13 Thumb Nuts

Key Features & Benefits at a Glance

• Enhanced grip and torque application with knurled round head design for secure hand-tightening in tight spaces
• Superior corrosion resistance thanks to black-oxide steel construction, extending component lifespan in harsh environments
• Optimized low-profile design (7/16" height) for applications with limited clearance without compromising strength
• Reliable coarse UNC threading (1/2"-13) with Class 2B fit ensures smooth engagement and vibration resistance
• Versatile mounting options with four 7/32" holes for secure secondary fastening or locking mechanisms
• Right-hand thread direction provides standard, intuitive installation for efficient assembly line operations
• Full regulatory compliance meeting RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

This low profile thumb nut delivers exceptional value in industrial settings where space constraints and frequent adjustments are common. The black-oxide steel construction provides superior corrosion protection compared to untreated alternatives, significantly reducing maintenance needs in manufacturing equipment, machinery guards, and outdoor applications. The knurled round head with 1-1/8" diameter offers maximum surface contact for hand tightening, eliminating the need for tools in maintenance-heavy environments. With its UNC coarse thread and Class 2B thread fit, this thumb nut ensures reliable performance in high-vibration applications while the four mounting holes allow for positive locking mechanisms, preventing accidental loosening in critical assemblies.

Specification Summary & Compliance

This thumb nut features precision 1/2"-13 UNC coarse threads with Class 2B thread fit for consistent engagement and right-hand thread direction. The component maintains dimensional accuracy with a head diameter of 1-1/8", height of 7/16", and includes four 7/32" mounting holes. Manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(a)-I and REACH (EC 1907/2006) standards, ensuring environmental regulatory compliance for industrial distribution and use.
