Electro Hardware THS1097M01F07 Brass Thumb Screw 10-32

Product Description

The ELECTRO HARDWARE THS1097M01F07 is a knurled-head brass thumb screw designed for hand-tightened fastening applications where tools are not practical or permitted. Built to 10-32 UNC thread standards, this screw features a shoulder design that provides a bearing surface for precise location and controlled clamping. The nickel finish offers corrosion resistance over the brass base material. The head measures 7/16 inches in diameter and 3/16 inches in height, with an overall length of 13/16 inches (0.8125 inches). The 3/8-inch shoulder diameter and 1/8-inch shoulder length make this a compact, precision-grade fastener suited for instrument panels, enclosures, and light mechanical assemblies.

This thumb screw is commonly used in electrical enclosures, control panels, instrumentation housings, HVAC equipment covers, and light-duty mechanical assemblies where repeated hand access is required. The knurled head provides grip for finger tightening without tooling. The shoulder design helps align mating components or provides a positive stop. This fastener is well suited for technicians and assemblers who regularly service or access equipment panels in the field or in a shop environment.

Key Features

Compatibility

Designed as a standard 10-32 UNC knurled thumb screw for use in electrical enclosures, control panels, instrumentation housings, and similar assemblies requiring hand-accessible fasteners with a shoulder bearing surface.

Installation Notes

Installation is performed by hand threading into a pre-tapped 10-32 UNC hole or threaded insert. De-energize any electrical equipment before accessing panels or enclosures secured by these fasteners. Avoid over-tightening, as brass is softer than steel and the threads can be damaged by excessive torque. Verify that the mating thread depth accommodates the shoulder length to ensure proper seating.
