Electro Hardware THN5006M01F16 Brass Thumb Nut 10-32 Unf

Product Description

The ELECTRO HARDWARE THN5006M01F16 is a round knurled thumb nut machined from Grade B633 brass with a 10-32 UNF thread form. It installs by hand without tools, making it a practical fastener for panels, enclosures, access covers, and equipment assemblies that require frequent removal or adjustment. The uncoated bright finish exposes the natural brass surface, which resists corrosion in typical indoor environments. With an overall height of 0.344 inches and a head diameter of 0.5 inches, this nut fits in compact spaces while still providing enough surface area for a secure finger grip. Electricians, HVAC technicians, and mechanical assemblers commonly use thumb nuts like this one on control panels, junction boxes, and service covers.

This thumb nut is suited for light-duty fastening applications in residential and commercial equipment where hand-tightened hardware is preferred over tool-driven fasteners. Typical uses include securing access panels on HVAC units, electrical enclosures, and instrumentation housings. The 10-32 UNF thread is a fine-pitch unified thread used across a wide range of trade and OEM hardware. The knurled round head provides reliable grip for repeated install and removal cycles without damaging mating surfaces.

Compatibility

Designed as a standard 10-32 UNF thumb nut for use in any application requiring a hand-tightened brass fastener at that thread size, including panel assemblies, enclosures, and service covers.

Installation Notes

Thumb nuts are installed and removed by hand; no wrench is required or recommended, as tool use risks deforming the knurled head. Ensure the mating threaded insert or stud is clean and free of debris before threading on the nut. Power down or de-energize any electrical enclosure before servicing fasteners on live panels, per NEC guidelines. Inspect threads for cross-threading or wear during each reinstallation.
