Value Collection 1-DER-10-M7- Iron Thumb Screw 5/16-18

Product Description

The VALUE COLLECTION 1-DER-10-M7- is a winged iron thumb screw designed for manual fastening applications where tools are not required. It features a 5/16-18 UNC thread and a 2-inch length under the head, with an overall length of 2.75 inches. The winged head allows for quick hand-tightening and loosening, making it well suited for jigs, fixtures, guards, and equipment panels that require frequent access. The screw is made from grade 32510 iron with an uncoated finish and includes a shoulder for positive seating against mating components. Licensed trade professionals and maintenance technicians working with industrial or mechanical assemblies will find this a straightforward replacement or new-build fastener.

This thumb screw is used in a wide range of industrial, mechanical, and light structural applications. It is appropriate for use in machine guarding, enclosure panels, fixture assemblies, and shop equipment where hand-operated fastening is preferred. The shoulder configuration provides a defined bearing surface, making it particularly useful where alignment or a positive stop is needed. It is sold and packaged individually, making it a practical choice for single-unit replacement or low-volume assembly work.

Compatibility

Designed as a standard inch-series thumb screw for use with any 5/16-18 UNC tapped hole in machine fixtures, equipment panels, or structural assemblies requiring manual fastening.

Installation Notes

Installation requires only hand tightening in most applications; do not use tools on the winged head as this may crack or deform the wings. Ensure the mating tapped hole is clean and free of debris before threading in the screw. For applications involving vibration, consider a locking washer or thread-locking compound to prevent loosening over time.
