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

Product Description

The VALUE COLLECTION 1-EFT-07-M7- is a winged iron thumb screw designed for hand-tightening applications where tools are not practical or available. Built to UNC thread standards with a 3/8-16 thread size, this fastener features a 3-inch length under the head and an overall length of 3-7/8 inches. The winged head design allows for firm finger grip and quick adjustments without a driver. Finished uncoated, it is suited for general mechanical, HVAC panel, and equipment assembly applications. Licensed trades and maintenance technicians will find this screw useful wherever repeated hand-access is needed at an access point, panel, or removable assembly.

This thumb screw is appropriate for use in light industrial, commercial, and residential trade settings where a manually adjustable fastener is required. Its shoulder construction — with a 5/8-inch shoulder diameter — provides a positive seating surface, making it a reliable choice for panel retention, jig fixtures, and equipment covers. The 1-13/16-inch head diameter gives a wide bearing surface for secure hand torque.

Key Features

• Winged head design enables tool-free hand tightening and loosening
• 3/8-16 UNC thread standard for broad compatibility with standard tapped hardware
• With-shoulder configuration provides a defined seating surface at 5/8-inch shoulder diameter
• 1-13/16-inch head diameter delivers wide grip area for finger torque
• Uncoated iron construction suited for dry indoor fastening applications
• 3-inch length under head with 3-7/8-inch overall length for standard panel depth clearance

Compatibility

Designed as a general-purpose UNC thumb screw for use in standard 3/8-16 tapped holes in panels, fixtures, and equipment assemblies requiring hand-adjustable fasteners.

Installation Notes

Installation requires no tools — hand-tighten only to the torque achievable by finger grip. Ensure the mating tapped hole is clean and free of debris before threading. Do not use power tools or wrenches on the winged head, as the wings are not rated for driven installation. Verify thread engagement depth is sufficient for the application load before placing the assembly in service.
