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

Product Description

The VALUE COLLECTION 1-EFL-07-17- is a winged iron thumb screw with a 3/8-16 UNC thread and a 1 inch length under the head. It features a shouldered shank and a zinc finish for basic corrosion resistance. The overall length is 1-7/8 inches, with a wide 1-13/16 inch winged head diameter designed for hand-tightening without tools. Made from grade 32510 iron, this thumb screw suits maintenance, assembly, and fastening applications where frequent manual adjustment is required. It is installed by technicians and tradespeople working on panels, enclosures, fixtures, or equipment covers across HVAC, electrical, and general mechanical trades.

This thumb screw is suited for applications requiring tool-free fastening and removal. The winged head provides sufficient grip for hand-tightening in tight spaces or on access panels. The shouldered design provides a defined bearing surface against the mating part. It is a standard inch-series fastener used in light-duty assemblies, service panels, guards, and equipment housings in both residential and commercial settings.

Compatibility

Designed as an OEM-style replacement or standard service thumb screw for equipment panels, access covers, and enclosures requiring 3/8-16 UNC threaded fasteners with a winged head profile.

Installation Notes

This thumb screw is installed by hand and requires no special tools for normal tightening. Always de-energize electrical panels or equipment before removing or replacing fasteners on live enclosures. Ensure the mating threaded hole or insert is clean and free of debris before installation. Do not over-torque by using a wrench on the winged head, as the iron construction is rated for hand-tightening loads only.
