Value Collection 1-EFR-07-17- Iron Thumb Screw 3/8-16

Product Description

The VALUE COLLECTION 1-EFR-07-17- is a winged iron thumb screw designed for hand-tightening applications where tools are not practical or available. Built to a 3/8-16 UNC thread standard, it features a 2-inch length under the head and an overall length of 2-7/8 inches. The winged head allows for firm finger-grip torque, making it well suited for assemblies that require frequent removal or adjustment. A zinc finish provides basic corrosion resistance. The shoulder design adds positional stability during installation. This fastener is sold individually and is used across a range of trade and industrial assembly scenarios.

This thumb screw is applicable in light mechanical assemblies, equipment panels, enclosures, and fixture mounting situations where repeated hand access is required. The 3/8-16 UNC thread pattern makes it compatible with standard tapped holes in steel, aluminum, and other common structural materials. It is appropriate for both shop fabrication and field service work where a tool-free fastening solution is specified.

Compatibility

Designed as a standard 3/8-16 UNC winged thumb screw for use in applications requiring tool-free fastening in hand-accessible assemblies.

Installation Notes

Installation is performed by hand; no tools are required for tightening under normal service loads. Ensure the mating tapped hole is clean and thread-compatible before installation. Do not use an impact driver or wrench on the winged head, as this may damage the head or strip the threads. Inspect threads for wear or deformation before reuse in critical assemblies.
