Value Collection 1-CDP-10-M7- Iron Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION 1-CDP-10-M7- is an iron thumb screw with a winged head design, built for hand-tightening applications where tools are not practical or necessary. It features a 1/4-20 UNC thread and a length under head of 1-1/2 inches, with an overall length of 2-1/8 inches. The winged head allows secure finger grip for repeated removal and reinstallation. This fastener includes a shoulder, with a shoulder diameter of 7/16 inches, providing a positive bearing surface against the mating part. The uncoated iron construction is suited for indoor, light-duty mechanical assemblies. Installers in HVAC, plumbing, electrical, and general mechanical trades use this type of fastener for access panels, cover plates, and equipment enclosures.

This thumb screw is appropriate for residential and light commercial applications where hand-operated fastening is preferred. It fits standard 1/4-20 UNC threaded holes and is commonly used in equipment enclosures, control panel covers, junction box lids, and similar assemblies that require frequent access. The winged head style eliminates the need for a screwdriver, making it a practical choice for service points that technicians open and close regularly during maintenance or inspection routines.

Installation Notes

Installation requires no special tools due to the winged head design, though care should be taken not to cross-thread during initial engagement. Ensure the mating threaded hole is clean and free of debris before installation. Power down or de-energize any equipment before accessing panels or enclosures secured by these fasteners. Do not use impact tools on thumb screws, as this can damage the winged head or strip the threads.
