Value Collection 1-GHT-07-17- Iron Thumb Screw 1/2-13

Product Description

The VALUE COLLECTION 1-GHT-07-17- is a winged iron thumb screw designed for hand-tightened fastening applications where tools are impractical or unnecessary. It carries a 1/2-13 UNC thread size and measures 3 inches under the head, with an overall length of 4 inches. The winged head style allows for quick, tool-free installation and removal. A zinc finish provides basic corrosion resistance for general-purpose use. This fastener is typically installed by maintenance technicians, tradespeople, and mechanical assemblers working on panels, guards, access covers, and jigs that require frequent removal.

This thumb screw is suited for light industrial, mechanical, and trade applications where hand-tightened fastening is required. The with-shoulder design and 3/4-inch shoulder diameter provide a positive seating surface, making it appropriate for use in fixtures, equipment panels, and assemblies across HVAC, plumbing, and electrical trade settings. The 2-1/4-inch winged head diameter provides adequate grip for repeated hand operation without fatigue.

Installation Notes

Install and remove by hand only — do not use a wrench or power tool on the winged head, as this can damage the wings or the mating threads. Ensure the receiving threads are clean and free of debris before installation. Verify thread engagement depth is sufficient for the load being retained. Follow applicable equipment manufacturer guidelines and relevant mechanical codes when using fasteners in safety-critical assemblies.
