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

Product Description

The VALUE COLLECTION 1-DER-07-M7- is an iron thumb screw with a winged head profile, designed for hand-tightened fastening applications where tools are not required for assembly or adjustment. It carries a 5/16-18 UNC thread and measures 2 inches under the head, with an overall length of 2.75 inches. The winged head provides a firm grip surface for repeated manual fastening and loosening cycles. Finished uncoated, this thumb screw is suited for light-duty mechanical assemblies, jigs, fixtures, and equipment panels across industrial and trade settings. It ships individually and is sold per piece.

This thumb screw is appropriate for use in applications requiring frequent manual adjustment without tools, such as access panels, guard assemblies, fixture plates, and equipment enclosures. Its shouldered shank design provides positive seating against mating surfaces, making it a reliable choice for controlled clamping in mechanical and light fabrication environments. The 5/16-18 UNC thread makes it compatible with standard tapped holes common in North American trade and industrial equipment.

Key Features

Compatibility

Designed as a standard replacement or general-use thumb screw for applications with 5/16-18 UNC tapped holes requiring a winged, shouldered fastener in inch-measurement systems.

Installation Notes

Installation does not require power tools and is typically performed by hand. Ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading the iron fastener. Do not over-torque by wrench or driver, as the uncoated iron construction is intended for hand-tight service only. Inspect the mating surface and thread engagement before loading the assembly.
