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

Product Description

The VALUE COLLECTION 1-CDP-10-17- is a winged iron thumb screw designed for hand-tightening applications where tools are not practical or available. It features a 1/4-20 UNC thread, a 1-1/2 inch length under the head, and a zinc-plated finish that provides basic corrosion resistance. The winged head measures 1-3/8 inches in diameter and 5/8 inches in height, allowing solid finger grip and reliable clamping force. A 7/16 inch shoulder diameter is machined into the shank. This fastener is suited for use in light mechanical assemblies, enclosures, panels, and equipment access covers across HVAC, electrical, plumbing, and general trade applications.

This thumb screw is intended for installations where frequent hand removal and reinstallation is required, such as access panels on HVAC equipment, electrical enclosures, and light-duty mechanical fixtures. The 1/4-20 UNC thread is one of the most common fastener standards in North American trade equipment, making this screw a straightforward drop-in for a wide range of service scenarios. It is sold individually and is appropriate for both maintenance and original installation use.

Installation Notes

This thumb screw is installed and removed by hand without requiring tools. Before replacing or installing thumb screws on powered equipment such as electrical panels or HVAC units, de-energize the equipment and follow applicable lockout/tagout procedures in accordance with NFPA 70E. Inspect the mating threaded insert or nut for thread damage before installation. Do not overtighten by applying tools to the winged head, as this may strip threads or damage the wing.
