Electro Hardware THS3007M07F16 Thumb Screw 6-32 SS303

Product Description

The ELECTRO HARDWARE THS3007M07F16 is a 303 stainless steel knurled head thumb screw in the 6-32 UNC thread size. It features a 5/16 inch head diameter and a 3/16 inch head height, with an overall length of 1/2 inch and a thread length of 5/16 inch. The uncoated 303 stainless steel construction provides good corrosion resistance and machinability, making it a practical choice for enclosure panels, instrument housings, and light mechanical assemblies where tool-free fastening is needed. This screw ships individually but requires a minimum order of 10 units.

This thumb screw is suited for applications in electrical enclosures, HVAC equipment access panels, control boxes, and light-duty mechanical assemblies where frequent hand-tightening and removal are required. Its knurled head provides grip without tooling, making it appropriate for service panels that technicians open and close regularly. The without-shoulder design seats flush against mating surfaces for clean, snag-free installations.

Key Features

Compatibility

Designed as a standard 6-32 UNC knurled head thumb screw for use in electrical enclosures, instrument panels, and light mechanical assemblies requiring tool-free fastener access.

Installation Notes

Hand-tighten only — do not use a driver or wrench on knurled thumb screws, as this can strip the head or damage mating threads. Ensure the mating tapped hole or nut thread is clean and free of debris before installation. De-energize any electrical enclosure or panel before removing or installing fasteners on live equipment. Follow applicable NEC or equipment manufacturer guidelines for enclosure access and closure.
