Value Collection 1-CDG-10-17- Iron Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION 1-CDG-10-17- is a winged iron thumb screw designed for hand-tightened fastening applications where tools are not required. Built to a 1/4-20 UNC thread standard, it features a 1/2-inch length under the head and a 1-3/8-inch-diameter winged head for easy finger grip. The screw includes a shoulder, with a shoulder diameter of 7/16 inch. A zinc finish provides basic corrosion resistance for general service environments. This fastener suits technicians and tradespeople who need reliable, repeatable hand-tightened connections in panels, enclosures, jigs, and equipment assemblies.

This thumb screw is appropriate for light to medium-duty fastening in HVAC panels, electrical enclosures, plumbing access covers, equipment guards, and similar assemblies where frequent removal and reinstallation are required without tools. The winged head style allows for consistent hand torque in confined or frequently serviced locations. It is sold individually and is well-suited for both field service and bench repair applications.

Installation Notes

Install by hand into a pre-tapped 1/4-20 UNC threaded hole. No power tools are required or recommended, as over-torquing can damage the winged head or strip the thread. Confirm the mating thread depth accommodates the 1/2-inch length under the head before installation. Inspect threads for debris or damage before seating the fastener.
