Electro Hardware THN5003M07F16 Thumb Nut 6-32 Unc

Product Description

The ELECTRO HARDWARE THN5003M07F16 is a round knurled thumb nut machined from Grade 302/303 stainless steel with a bright, uncoated finish. It accepts a 6-32 UNC threaded fastener and measures 0.281 inches overall height with a 0.375-inch head diameter and a 0.343-inch base diameter. The knurled outer surface provides a firm grip for hand-tightening without tools. This thumb nut meets QQ-S-763 standards, making it appropriate for use in corrosion-resistant and cleanable assemblies. Electricians, HVAC technicians, and equipment fabricators commonly use this hardware when panels, covers, or access doors require frequent removal and reinstallation.

This thumb nut is suited for light-duty fastening applications in control panels, electrical enclosures, HVAC equipment housings, and general equipment assemblies where a tool-free fastener is needed. Its stainless steel construction makes it a reliable choice in environments exposed to moisture, mild chemicals, or frequent handling. It is typically installed alongside mating machine screws or threaded standoffs in 6-32 UNC configuration.

Key Features

• 6-32 UNC thread for compatibility with standard machine screw configurations
• Grade 302/303 stainless steel construction for corrosion resistance
• Bright, uncoated finish meets QQ-S-763 standard
• Round knurled head design allows hand-tightening without tools
• Compact profile: 0.281 inches overall height, 0.375-inch head diameter

Compatibility

Designed as a standard 6-32 UNC thumb nut for use with mating machine screws, threaded standoffs, and inserts in that thread size across control panels, enclosures, and equipment assemblies.

Installation Notes

Installation is performed by hand threading the nut onto a mating 6-32 UNC screw or standoff. De-energize any electrical panel or equipment before servicing fasteners on live enclosures, in accordance with applicable NEC lockout/tagout requirements. Do not over-torque by using tools, as the knurled grip is designed for hand-tight service only, which may damage the thread or mating hardware.
