Value Collection 1-DEP-07-17- Iron Thumb Screw 5/16-18

Product Description

The VALUE COLLECTION 1-DEP-07-17- is a winged iron thumb screw designed for hand-tightening applications where tools are not required or practical. It features a 5/16-18 UNC thread, a length under head of 1.5 inches, and an overall length of 2.25 inches. The broad 1.75-inch winged head provides enough grip surface for reliable hand torque in assembly, adjustment, and fixture-mounting tasks. The zinc-plated finish provides basic corrosion resistance for indoor and light-duty industrial use. This fastener is sold individually and suits trades and shop environments where frequent removal and reinstallation are required without specialized tooling.

This thumb screw is suited for use in panel assemblies, jigs, fixtures, enclosures, and equipment covers across HVAC, electrical, plumbing, and general mechanical applications. The with-shoulder design adds a bearing surface that helps distribute clamping load and keeps the screw aligned during repeated hand operation. It is appropriate for light-duty fastening in residential and commercial settings where a 5/16-18 UNC threaded hole or insert is present.

Installation Notes

Installation requires no special tools — hand-tighten only to avoid stripping the threaded hole or damaging the winged head. Ensure the mating thread is clean, undamaged, and matches the 5/16-18 UNC standard before installation. Power down or de-energize any equipment before accessing internal panels or enclosures where this fastener is used. Do not use an impact driver or power tool to drive this thumb screw.
