Professional Applications & Engineering Value

This low profile thumb nut is engineered to address common challenges in industrial maintenance and assembly, where tool access is restricted and corrosion resistance is critical. The black-oxide steel material provides a durable barrier against moisture and chemicals, reducing downtime due to fastener failure. Its knurled head texture and generous 1 3/8" diameter enable operators to apply sufficient torque by hand, speeding up adjustments in conveyor systems, packaging machinery, and agricultural equipment. The UNC coarse thread and Class 2B thread fit ensure rapid installation and reliable holding power, even in high-vibration environments like automotive or construction applications. With integrated mounting holes, it simplifies alignment in fixture setups, enhancing productivity while meeting stringent RoHS and REACH compliance for global supply chains.

Specification Summary & Compliance

This thumb nut adheres to UNC thread standards with a Class 2B thread fit for consistent dimensional accuracy. It is manufactured from black-oxide steel with a low-profile, round head design, 1/2" height, and 1 3/8" head diameter. The product is confirmed to be RoHS 3 (2015/863/EU) compliant under exemption 6(a)-I and REACH (EC 1907/2006) compliant as of the latest assessment, ensuring it meets environmental and safety regulations for industrial use.
