Electro Hardware THS1056M04F16 Aluminum Thumb Screw 8-32

Product Description

The ELECTRO HARDWARE THS1056M04F16 is an aluminum thumb screw with a knurled head and integral shoulder, designed for tool-free fastening applications in panels, enclosures, and equipment assemblies. The 8-32 UNC thread provides a standard coarse-thread engagement suitable for aluminum, plastic, and light steel panels. The knurled head allows secure finger-tightening without a driver, while the 3/8-inch shoulder diameter provides a positive seating surface against the mating panel or housing. At 0.8125 inches overall length, this fastener suits shallow-depth fastening points common in HVAC control panels, electrical enclosures, and similar trade equipment.

This thumb screw is used in residential and light commercial applications where frequent access panels, junction boxes, filter frames, or equipment covers require repeated removal and reinstallation without tools. The uncoated aluminum finish keeps weight low and resists corrosion in dry or low-humidity indoor environments. HVAC technicians, electricians, and panel fabricators commonly specify this fastener for control boards, access doors, and field-assembled equipment where hand-tightening is required. It meets QQ-A-225A Comp 2 and T-3 standards.

Installation Notes

Installation requires no tools under normal service conditions. Verify that the mating threaded insert or tapped hole is clean and free of debris before engaging the thread. Do not over-torque by hand; aluminum threads can strip if forced against an obstructed or cross-threaded hole. Minimum order quantity for this fastener is 10 pieces.
