Electro Hardware THS3023M01F07 Brass Thumb Screw 8-32

Product Description

The ELECTRO HARDWARE THS3023M01F07 is a brass thumb screw designed for hand-tightening applications where tools are not practical or accessible. It features an 8-32 UNC thread with a knurled head for secure finger grip and is finished in nickel for corrosion resistance. The overall length is 9/16 inches with a thread length of 3/8 inches. The head measures 3/8 inches in diameter and 3/16 inches in height. Manufactured from brass with a nickel finish conforming to QQ-N-290A, this fastener suits electrical enclosures, instrumentation panels, and light-duty mechanical assemblies where frequent removal is required.

This thumb screw is suited for use in residential and commercial applications including control panels, enclosure covers, HVAC equipment access panels, and instrumentation housings. It is installed without shoulder, making it appropriate for through-hole or threaded-insert applications where flush or near-flush seating is needed. Technicians working with low-voltage control boards, junction boxes, or field-serviceable assemblies will find this fastener appropriate for locations requiring repeated hand access.

Key Features

• 8-32 UNC thread for compatibility with standard inch-series threaded holes and inserts
• Knurled brass head allows secure finger-tightening without tools
• Nickel finish meets QQ-N-290A specification for corrosion resistance
• Without-shoulder design suits through-hole and threaded-insert installations
• Meets multiple material and finish standards including ASTM B633, QQ-B-626B Comp 22, and QQ-S-763
• Compact head profile at 3/8 inches diameter and 3/16 inches height for space-constrained panel work

Compatibility

Designed as an OEM-style replacement or stock fastener for assemblies using 8-32 UNC inch-series threaded holes requiring a knurled brass thumb screw without shoulder.

Installation Notes

This fastener is installed by hand and does not require a driver in standard applications. Ensure the mating threaded hole or insert is clean and free of debris before installation. Do not over-torque by using tools, as the brass material and knurled head are designed for hand pressure only. Follow applicable NEC or equipment manufacturer guidelines when securing electrical enclosure covers or control panel access plates.
