Electro Hardware THS1053M01F07 Brass Thumb Screw 8-32

Product Description

The ELECTRO HARDWARE THS1053M01F07 is a brass thumb screw designed for hand-tightening applications where tools are not practical or accessible. It features an 8-32 UNC thread, a knurled head for secure finger grip, and a shouldered shank that registers precisely in clearance holes to control thread engagement depth. The head measures 7/16 inches in diameter and 3/16 inches in height. The screw has an overall length of 5/8 inches with a 3/8-inch shoulder diameter and a 1/8-inch shoulder length. A nickel finish over the brass body provides mild corrosion resistance and a clean appearance suitable for panel and enclosure work.

This thumb screw is used in light industrial, electronic enclosure, and panel assembly applications where frequent manual removal and reinstallation is required. The shouldered design makes it well-suited for sheet metal panels, instrument covers, and access doors where radial location of the fastener is as important as axial clamping. It is commonly installed by electricians, instrumentation technicians, and mechanical assemblers working on control panels, junction boxes, and equipment housings.

Compatibility

Designed as a standard UNC inch-series thumb screw for use in applications requiring 8-32 tapped holes and a shouldered fastener with a knurled head.

Installation Notes

Installation requires a pre-tapped 8-32 UNC hole in the mating component. Power down or de-energize any equipment before servicing panels or enclosures where this fastener is used. Hand-tighten only — do not use a driver or wrench on the knurled head, as the head is not designed for tool torque. Verify shoulder fit in the clearance hole before full thread engagement to ensure proper seating.
