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

Product Description

The VALUE COLLECTION 1-GHR-07-17- is a winged thumb screw machined from iron with a zinc finish. It features a 1/2-13 UNC thread and a 2-inch length under the head, making it a hand-tightened fastener suited for applications where tools are not practical or required. The winged head allows finger-driven installation and removal, while the shoulder design provides a controlled seating surface. At 3 inches overall length and a head diameter of 2.25 inches, this screw is built for repeated hand-operated use in jigs, fixtures, enclosures, and mechanical assemblies. It weighs 0.22 pounds per piece.

This thumb screw is used in industrial, mechanical, and light fabrication settings where frequent manual access is needed. Typical applications include tooling fixtures, machine guards, access panels, and equipment enclosures. The winged head style is common in shop environments and field service contexts where gloved or bare-hand tightening is the norm. It is sold individually and is appropriate for both maintenance and original equipment assembly work.

Compatibility

Installation Notes

Installation is performed by hand without tools in most applications. Verify the receiving thread is clean and free of damage before installation. Do not use a wrench or pliers on the winged head, as the wings are not rated for tool torque and may deform. In applications subject to vibration, a locking element such as a thread-locking insert or secondary fastener should be considered.
