Value Collection 1-EFP-07-M7- Iron Thumb Screw 3/8-16

Product Description

The VALUE COLLECTION 1-EFP-07-M7- is an iron thumb screw with a winged head design, intended for hand-tightened fastening applications where tools are not required. It features a 3/8-16 UNC thread and a 1-1/2 inch length under the head, giving it the grip and reach needed for panel access, jig fixtures, and light equipment assemblies. The uncoated iron construction suits indoor mechanical and industrial environments. A shoulder below the head provides a bearing surface that controls depth and protects mating materials during repeated hand-tightening cycles.

This thumb screw is suited for residential and light commercial applications where frequent manual adjustments or removals are needed without tools. Typical uses include equipment covers, control panel access doors, filter housings, jig and fixture setups, and similar assemblies found in HVAC, electrical, and mechanical trades. The winged head profile provides enough grip surface for firm hand torque even with gloved hands. It is sold and packaged as a single unit.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes
• Winged head allows secure hand-tightening without tools
• Shoulder type construction provides a controlled bearing surface under the head
• 1-13/16 inch head diameter offers a wide grip area for easy actuation
• Uncoated iron construction suited for dry indoor mechanical environments
• Single-piece packaging for individual replacement or low-quantity needs

Compatibility

Designed as a standard UNC thumb screw replacement for assemblies requiring a 3/8-16 threaded fastener with a winged head and shoulder. Verify thread engagement depth and shoulder diameter against the mating component before installation.

Installation Notes

Installation requires only hand tools or no tools at all, though a wrench may be used for final snugging if the application demands it. Confirm the tapped hole thread standard matches 3/8-16 UNC before installation. Inspect mating threads for damage or contamination before seating the fastener. Do not over-torque by mechanical means, as the winged head design is intended for hand-controlled clamping force.
