Value Collection 1-DEP-07-M7- Iron Thumb Screw 5/16-18

Product Description

The VALUE COLLECTION 1-DEP-07-M7- is a winged iron thumb screw designed for hand-tightened fastening applications where tools are not required. Built with a 5/16-18 UNC thread and a 1-1/2 inch length under the head, this thumb screw features a shoulder design that provides positive bearing contact and controlled clamping depth. The overall length is 2-1/4 inches, and the uncoated iron construction keeps it straightforward for general-duty use. Machinists, maintenance technicians, and fabricators reach for this style of fastener when quick, repeated assembly and disassembly is part of the workflow.

This thumb screw is suited for light industrial, maintenance, and shop fixture applications where hand adjustment is preferred over wrench-driven fastening. The winged head with a 1-3/4 inch diameter and 3/4 inch head height gives a secure grip surface. The 5/8 inch shoulder diameter seats cleanly against mating components, making it a practical choice for jigs, fixtures, guards, access panels, and similar assemblies in machine shops, HVAC equipment enclosures, and general mechanical service environments.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard inch-system tapped holes
• Winged head design allows hand tightening without tools
• With-shoulder configuration provides controlled seating and positive bearing surface

Compatibility

Designed for use in standard 5/16-18 UNC tapped holes in inch-measurement assemblies. Typical applications include machine fixtures, shop jigs, access panels, and equipment guards requiring frequent hand-adjustment.

Installation Notes

This thumb screw is installed and removed by hand — no wrench or driver is required. Verify the mating tapped hole is clean, undamaged, and correctly sized for 5/16-18 UNC thread before installation. Do not exceed hand-tight torque; using tools to drive a winged thumb screw can strip threads or crack the head. For applications subject to vibration, consider a locking insert or thread-locking compound appropriate for the service environment.
