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

Product Description

The VALUE COLLECTION 1-EFT-07-17- is a winged iron thumb screw designed for hand-tightened fastening applications where tools are not practical or required. Built to a 3/8-16 UNC thread standard, it provides reliable clamping force in assemblies that need frequent adjustment or removal. The winged head allows secure finger-grip tightening without a driver. Finished in zinc for basic corrosion resistance, this thumb screw suits light industrial, mechanical, and maintenance applications. The shoulder design helps locate and stabilize the fastener within a mating bore during installation and service.

This thumb screw is suited for use in jigs, fixtures, enclosures, guards, and equipment panels where hand-operated fasteners are specified. It is commonly installed by maintenance technicians, fabricators, and trade professionals working on light mechanical assemblies. The 3/8-16 UNC thread is a standard coarse-thread configuration found across a wide range of industrial and commercial hardware applications.

Compatibility

Designed as a standard 3/8-16 UNC winged thumb screw for use in light industrial, mechanical, and commercial assemblies requiring hand-operated fastening. Confirm thread engagement depth and shoulder diameter clearance against the mating component before installation.

Installation Notes

Installation does not require power tools. Hand-tighten only to avoid stripping the threaded bore or damaging the winged head. Verify the mating thread is clean and free of debris before engagement. Apply thread lubricant or anti-seize only if required by the assembly specification.
