Value Collection 1-EFR-10-17- Iron Thumb Screw 3/8-16

Product Description

The VALUE COLLECTION 1-EFR-10-17- is a winged thumb screw machined from iron and finished in zinc for corrosion resistance. It features a 3/8-16 UNC thread with a 2-inch length under the head and an overall length of 2-7/8 inches. The winged head design allows hand-tightening without tools, making it well suited for assemblies that require frequent removal or adjustment. A shoulder is incorporated below the head, with a shoulder diameter of 5/8 inches. This fastener is used by tradespeople and assemblers who need a reliable, tool-free fastening solution in light to medium-duty applications.

This thumb screw is appropriate for use in general mechanical assemblies, equipment panels, enclosures, and maintenance access points where hand operation is preferred. The zinc finish provides a measure of protection against light corrosion in typical indoor environments. The with-shoulder configuration helps locate and retain mating components during assembly, making it practical for panel covers, guards, and similar removable components in HVAC equipment, electrical enclosures, and plumbing access panels.

Installation Notes

Installation does not require power tools; hand-tighten only using the winged head. Ensure the mating tapped hole is clean and free of debris before threading. Do not use a wrench or driver on the wings, as this can crack or deform the iron head. Verify thread engagement is sufficient for the load requirements of the application before placing the assembly in service.
