Electro Hardware THS3023M01F21 Brass Thumb Screw 8-32

Product Description

The ELECTRO HARDWARE THS3023M01F21 is a brass thumb screw with an 8-32 UNC thread and a knurled head designed for tool-free hand tightening in light-duty fastening applications. Machined from brass with a zinc finish, the knurled head provides grip without tools, making it well-suited for panels, enclosures, access covers, and equipment housings where frequent removal is expected. The screw measures 9/16 inches in overall length with a 3/8 inch head diameter and a 3/16 inch head height. It is a without-shoulder design, conforming to inch measurement standards and multiple material and plating specifications.

This thumb screw is used across electrical, HVAC, plumbing, and general trade applications wherever a hand-adjustable fastener is needed. Typical installations include control panel covers, junction box lids, equipment doors, and light-gauge sheet metal assemblies that require routine access. The 8-32 UNC thread is a widely used standard size compatible with pre-tapped holes and threaded inserts found in commercial and residential equipment enclosures.

Installation Notes

Install by hand into a pre-tapped 8-32 UNC hole or threaded insert. De-energize any electrical enclosure or control panel before opening access covers or installing fasteners. Do not overtighten, as brass threads can be damaged by excessive torque or the use of power tools. Verify thread engagement depth is adequate for the application before placing the assembly into service.
