Electro Hardware THS3010M01F21 Brass Thumb Screw 6-32

Product Description

The ELECTRO HARDWARE THS3010M01F21 is a brass thumb screw with a 6-32 UNC thread and a knurled head designed for tool-free hand tightening. The knurled head measures 5/16 inches in diameter and 3/16 inches in height, providing a firm grip surface without requiring a driver. The overall length is 11/16 inches with a 1/2 inch thread length and no shoulder. Finished with a zinc coating over brass, this fastener meets ASTM B633, QQ-B-626B Comp 22 Type 1 standards. It suits applications where frequent removal and reinstallation are required and metal corrosion resistance matters.

This thumb screw is used in light-duty assembly, panel mounting, enclosure covers, and instrument housing where hand-adjustable fastening is needed. Typical applications include electrical enclosures, control panels, HVAC equipment covers, and general sheet metal assemblies. The 6-32 UNC thread is a common size found in electronic chassis, junction boxes, and equipment access panels across residential and commercial installations.

Compatibility

Designed as a standard 6-32 UNC thumb screw replacement or new installation fastener for electrical enclosures, control panel covers, and equipment access panels requiring hand-removable fastening.

Installation Notes

Installation requires a pre-tapped or threaded insert sized for 6-32 UNC threads in the mating component. Hand-tighten only — applying a driver or wrench to the knurled head can damage the head profile or over-torque the threaded engagement. Ensure the mating panel or chassis thread depth accommodates the 1/2 inch thread length before installation. De-energize electrical equipment before accessing any panel secured by these fasteners.
