Electro Hardware THS1012M04F16 Aluminum Thumb Screw 6-32

Product Description

The ELECTRO HARDWARE THS1012M04F16 is an aluminum thumb screw with a knurled head, designed for tool-free fastening in light-duty assemblies and enclosures. It features a 6-32 UNC thread and a shouldered shank, allowing controlled depth engagement without overdriving. The knurled head profile provides reliable finger grip for quick installation and removal without tools. This fastener is well suited for HVAC panels, electrical enclosures, access covers, and control box assemblies where repeated hand-tightening is required. At 0.75 inches overall length and 0.375 inches head diameter, it fits compact mounting applications.

This thumb screw is used in residential and commercial applications wherever a tool-free fastener is needed on removable panels, junction box covers, filter frames, or equipment access doors. The shoulder design registers against the mating surface to prevent thread engagement beyond a set depth, which helps protect delicate panels and thin sheet metal. Electricians, HVAC technicians, and panel fabricators commonly use this style of fastener during assembly and routine service access.

Compatibility

Designed as a standard 6-32 UNC thumb screw replacement for use in HVAC panels, electrical enclosures, access covers, and similar light-duty assemblies requiring tool-free fastening.

Installation Notes

Installation requires no tools — finger-tighten only to avoid stripping the aluminum thread. Confirm the mating tapped hole is clean and free of debris before engagement. Power down or de-energize any equipment before servicing panels or enclosures where this fastener is used. Do not use an impact driver or wrench on this fastener.
