Electro Hardware THN5001M07F16 Thumb Nut 2-56 Unc

Product Description

The ELECTRO HARDWARE THN5001M07F16 is a round knurled thumb nut machined from Grade 302 and 303 stainless steel for corrosion-resistant, tool-free fastening in light-duty assemblies. The 2-56 UNC thread form suits small-diameter threaded studs and machine screws commonly found in instrumentation panels, electrical enclosures, and HVAC control assemblies. The knurled head provides positive finger grip without a driver, making it well suited for components that require frequent access. Overall height is 0.25 inches and head diameter is 0.25 inches, keeping the installed footprint compact. The uncoated bright finish meets QQ-S-763 stainless steel standards.

This thumb nut is used in residential and light commercial applications where a captive or retained fastener must be removed and reinstalled by hand. Typical install scenarios include securing access panels, instrument bezels, and small sub-assemblies inside electrical or control enclosures. The 2-56 UNC thread is a fine-pitch option for thin-material applications. It is installed by electricians, HVAC technicians, and panel-assembly mechanics working on low-voltage control boards, junction boxes, and similar equipment where stainless steel hardware resists condensation-related corrosion.

Key Features

• 2-56 UNC thread for use with standard small-diameter machine screws and threaded studs
• Grade 302 and 303 stainless steel construction provides corrosion resistance in humid or wet environments
• Round knurled head allows secure hand-tightening without tools
• Uncoated bright finish meets QQ-S-763 stainless steel material standard
• Compact 0.25-inch overall height and 0.25-inch head diameter for tight-clearance installations

Compatibility

Designed as an OEM-style replacement or service fastener for assemblies using 2-56 UNC threaded hardware in electrical enclosures, control panels, and instrumentation equipment.

Installation Notes

Installation is performed by hand; thread the nut onto a compatible 2-56 UNC stud or machine screw and finger-tighten only. De-energize any electrical panel or control enclosure before accessing internal hardware per applicable NEC guidelines. Inspect the mating thread for damage or contamination before installation. Minimum order quantity is 10 units.
