Value Collection 1-EFR-10-M7- Iron Thumb Screw 3/8-16

Product Description

The VALUE COLLECTION 1-EFR-10-M7- is an iron winged thumb screw designed for hand-tightened fastening applications in light industrial, mechanical, and maintenance settings. It features a 3/8-16 UNC thread and a 2-inch length under the head, making it a practical choice where frequent manual adjustment or removal is required without tools. The winged head provides grip surface for finger tightening, and the shoulder configuration helps maintain precise positioning at the fastening point. At 0.1 pounds, this is a lightweight single-piece fastener suited for low-torque clamping and retention tasks. It is supplied individually with no finish coating, ready for immediate use.

This thumb screw is used in general mechanical assemblies, jigs, fixtures, guards, and access panels where tool-free fastening is preferred. The 3/8-16 UNC thread is a standard coarse-thread size widely used in North American trade applications. The shoulder configuration allows it to serve as a locating or alignment pin in addition to a fastener. Maintenance technicians, machinists, and field service professionals commonly install this type of hardware in equipment enclosures and adjustable assemblies requiring routine access.

Installation Notes

This fastener is installed by hand into a pre-tapped 3/8-16 UNC hole. Ensure the mating thread is clean and free of debris before installation. Do not use power tools to drive a winged thumb screw, as the head is not designed for mechanical torque. Inspect the shoulder seat and mating bore for burrs or damage that could affect seating before final assembly.
