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

Product Description

The VALUE COLLECTION 1-DEJ-10-M7- is a winged iron thumb screw designed for hand-tightening applications where tools are not practical or required. Featuring a 5/16-18 UNC thread and a 3/4-inch length under the head, this fastener provides secure, tool-free clamping in light-duty assemblies. The oversized winged head — 1-1/2 inches in diameter and 3/4 inches tall — gives fingers a solid grip surface. Made from grade 32510 iron with an uncoated finish, it is suited for indoor mechanical assemblies, jigs, fixtures, and equipment panels where corrosion exposure is minimal. Machinists, maintenance technicians, and fabricators commonly install this type of hardware.

This thumb screw is appropriate for use in indoor mechanical assemblies, tooling setups, and light-duty clamping fixtures. The 5/16-18 UNC thread is a standard coarse-thread designation, making it compatible with a wide range of tapped holes and standard threaded inserts. Its shoulder design allows for controlled seating depth, making it suitable for panel-mount or access-cover applications in shop and facility maintenance environments.

Compatibility

Designed as a standard inch-series thumb screw for use in tapped holes sized to 5/16-18 UNC thread specifications in light-duty mechanical assemblies and fixtures.

Installation Notes

This fastener is installed by hand in pre-tapped 5/16-18 UNC holes. Ensure the mating thread is clean and free of debris before installation. Do not use a wrench or driver on the winged head, as the iron construction can fracture under tool-applied torque. In applications subject to vibration, consider a locking washer or thread-locking compound appropriate for the service environment.
