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

Product Description

The VALUE COLLECTION 1-EFL-07-M7- is a winged iron thumb screw designed for hand-tightened fastening applications where tools are not required or practical. Built to UNC thread standards with a 3/8-16 thread size, this fastener features a 1 inch length under the head and an overall length of 1-7/8 inches. The winged head design provides sufficient grip surface for manual torque, and the with-shoulder construction adds controlled seating depth. Supplied in an uncoated iron finish, this fastener suits general industrial and mechanical assembly tasks. Licensed tradespeople and maintenance technicians working on panel access points, enclosures, jigs, and fixtures commonly specify this style of thumb screw.

This thumb screw is suited to applications requiring frequent hand removal and reinstallation without tooling. Common uses include access panel retention, fixture alignment pins, adjustable stops, and light-duty clamping in industrial, HVAC, electrical, and mechanical enclosure work. The shouldered body helps locate mating parts consistently across repeated assembly cycles. The uncoated iron construction is appropriate for indoor or protected environments where corrosion exposure is minimal.

Key Features

• Winged head for tool-free hand tightening and removal
• 3/8-16 UNC thread for broad compatibility with standard tapped holes
• With-shoulder design for consistent part location and controlled seating
• 1 inch length under head suits standard panel and enclosure wall thicknesses
• Uncoated iron construction for general-purpose indoor fastening
• 1-13/16 inch head diameter provides adequate grip surface for manual operation

Compatibility

Designed as a standard UNC 3/8-16 thumb screw for use in any tapped hole or threaded insert meeting that thread specification in industrial, mechanical, and enclosure assembly applications.

Installation Notes

Installation requires a pre-tapped or threaded-insert hole sized for 3/8-16 UNC thread. Hand-tighten only — the winged head is not designed for wrench or driver engagement. Ensure mating threads are clean and free of debris before installation. For applications in electrical enclosures, de-energize all circuits before performing any panel or cover work in accordance with NFPA 70 (NEC) requirements.
