Electro Hardware THN5005M07F16 Thumb Nut 10-24 Unc

Product Description

The ELECTRO HARDWARE THN5005M07F16 is a round knurled thumb nut machined from Grade 302/303 stainless steel with an uncoated, bright finish. It features a 10-24 UNC thread and is designed for hand-tightening applications where tools are not practical or desirable. The knurled head provides grip for firm finger tightening, and the stainless steel construction resists corrosion in wet or chemically exposed environments. With a head diameter of 0.5 inches and an overall height of 0.344 inches, this is a compact fastener suited for panel assemblies, enclosures, and equipment covers. Meets QQ-S-763 standards for stainless steel fasteners.

This thumb nut is used in light industrial, electrical, HVAC, and mechanical panel applications where frequent access or adjustment is required without tools. Its 10-24 UNC thread is one of the most common inch-series machine screw threads, making it compatible with a wide range of standard threaded inserts, standoffs, and studs. Typical install scenarios include instrument enclosures, control panels, access covers, and field-serviceable equipment assemblies. The uncoated stainless finish suits both indoor and moderately corrosive outdoor environments.

Installation Notes

Installation is performed by hand; no tools are required or recommended for standard torque applications. Ensure mating threads are clean and free of debris before installation to prevent galling, which is a common risk with stainless steel fasteners threading against stainless steel mating components. Apply an appropriate anti-seize compound if repeated removal is expected. Follow applicable equipment or panel manufacturer guidelines for fastener seating requirements.
