Electro Hardware THS3052M01F07 Brass Thumb Screw 1/4-20

Product Description

The ELECTRO HARDWARE THS3052M01F07 is a brass thumb screw designed for hand-tightened fastening applications where tools are not practical or accessible. It features a knurled head that provides grip for finger-driven installation and removal. The screw uses a 1/4-20 UNC thread standard and measures 0.75 inches in overall length with a thread length of 0.5 inches. The head is 0.5 inches in diameter and 0.25 inches in height. A nickel finish provides corrosion resistance. This fastener is suited for use by electricians, HVAC technicians, panel fabricators, and general trade professionals who require a reliable, hand-operable fastening solution.

This thumb screw is appropriate for light-duty panel covers, access doors, junction enclosures, and equipment housings where frequent removal and re-installation is expected. The knurled head style and nickel finish make it a practical choice for indoor enclosures and control panels in residential and light commercial applications. The shoulder-free design allows flush or near-flush seating against mating surfaces without a shoulder step.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• Knurled head for secure finger grip without tools
• Brass construction with nickel finish for corrosion resistance
• 0.5-inch head diameter and 0.25-inch head height for low-profile clearance

Compatibility

Designed for use in standard 1/4-20 UNC tapped holes. Suitable for panel covers, enclosures, and access panels requiring hand-tightened fasteners in trade and light industrial applications.

Installation Notes

Hand-tighten only. Do not use a driver or wrench on the knurled head, as over-torquing can strip the brass threads or damage the head. Verify the mating hole is tapped to 1/4-20 UNC before installation. Ensure power is off and equipment is de-energized before opening any panel or enclosure for fastener service.
