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

Product Description

The VALUE COLLECTION 1-GHS-07-17- is a winged iron thumb screw designed for hand-tightened fastening applications where tools are not required. The screw features a 1/2-13 UNC thread and a zinc finish over a grade 32510 iron body, providing corrosion resistance for general-purpose use. It carries an overall length of 3-1/2 inches with a length under head of 2-1/2 inches. The winged head design allows for quick installation and removal by hand. This type of fastener is commonly installed by maintenance technicians, tradespeople, and mechanical assemblers in panel, enclosure, and equipment-mounting applications.

This thumb screw is suited for use in assemblies requiring frequent manual access, such as electrical enclosures, equipment panels, HVAC access doors, and mechanical jigs or fixtures. The shouldered shank with a 3/4-inch shoulder diameter provides a positive seat against mating surfaces, reducing the likelihood of fastener pull-through or misalignment. The 2-1/4-inch head diameter and 1-inch head height offer sufficient grip surface for reliable hand tightening without tools.

Compatibility

Designed as a standard inch-system thumb screw for use in assemblies, enclosures, and fixtures that accept a 1/2-13 UNC threaded fastener with a shouldered shank.

Installation Notes

Installation requires no special tools; hand-tighten only to avoid thread damage on the mating component. Ensure the mating threads are clean and free of debris before installation. Do not use power tools or wrenches on the winged head, as the head geometry is not rated for torqued installation. Follow applicable equipment manufacturer guidelines when using this fastener in load-bearing or safety-critical assemblies.
