Electro Hardware THS3007M01F21 Brass Thumb Screw 6-32

Product Description

The ELECTRO HARDWARE THS3007M01F21 is a brass thumb screw designed for hand-tightened fastening applications where tools are not required or practical. It features a 6-32 UNC thread and a knurled head that provides positive grip without tooling. The screw measures 0.5 inches in overall length with a 5/16-inch (0.3125 inches) head diameter and a 3/16-inch (0.1875 inches) head height. Constructed from brass with a zinc finish, it is suited for light-duty panel, enclosure, and instrument assembly work where corrosion resistance and non-magnetic properties are priorities. Electricians, control panel builders, and instrumentation technicians are the primary installers.

This thumb screw is used in residential and commercial control panels, electrical enclosures, HVAC equipment access covers, and instrumentation housings. The 6-32 UNC thread is one of the most common thread sizes in low-voltage control and panel work, making this fastener broadly applicable wherever removable hand-tightened access is needed. The absence of a shoulder means the screw seats flush into standard tapped holes or threaded inserts without a standoff requirement.

Key Features

• 6-32 UNC thread standard for broad compatibility with common tapped holes in panels and enclosures
• Knurled head allows hand tightening and removal without tools
• Brass construction with zinc finish for corrosion resistance in light-duty environments
• Without-shoulder design seats directly into standard tapped holes
• Compact 0.5-inch overall length suits shallow panel and cover applications
• Meets multiple material and finish standards including ASTM B633

Compatibility

Designed as a standard UNC 6-32 thumb screw for use in tapped holes, threaded inserts, and hex standoffs found in electrical enclosures, control panels, and instrumentation housings requiring hand-removable fasteners.

Installation Notes

Installation requires no tools under normal hand-tightening conditions; do not use a driver or wrench, as brass threads are soft and will strip under excessive torque. Confirm the mating thread is clean and free of debris before installation. Electricians and panel builders should follow NEC guidelines for panel and enclosure work, including de-energizing equipment before servicing access covers secured by thumb screws.
