Value Collection 3120TS Steel Thumb Screw 5/16-18 Oval Head

Product Description

The VALUE COLLECTION 3120TS is a steel thumb screw with a 5/16-18 UNC thread and an oval head profile, designed for hand-tightened fastening applications where tools are not required or not practical. The screw features a shoulder design that provides a bearing surface between the fastened components. With a zinc finish for basic corrosion resistance, this thumb screw suits light-duty mechanical assemblies, panel access covers, enclosures, and equipment housings. It is commonly installed by maintenance technicians, assemblers, and field service professionals working on industrial and commercial equipment.

This thumb screw is suited for use in applications requiring frequent manual removal and reinstallation, such as access panels, guards, inspection covers, and light structural assemblies. The 5/16-18 UNC thread is a standard unified coarse thread, compatible with standard tapped holes of that specification. The with-shoulder configuration provides a defined bearing interface, making it well suited for through-hole mounting applications where the shoulder acts as a locating or load-bearing feature.

Key Features

• 5/16-18 UNC thread for compatibility with standard tapped holes
• Oval head profile for comfortable hand actuation without tools
• With-shoulder design provides a bearing surface and through-hole location
• Zinc finish offers basic corrosion protection for general indoor use
• Steel construction for reliable strength in light-duty fastening

Compatibility

Designed as a standard UNC thumb screw replacement or new installation fastener for any assembly using a 5/16-18 tapped hole requiring a shoulder-type oval head thumb screw in steel with zinc finish.

Installation Notes

Installation is performed by hand; no tools are required for normal operation. Ensure the mating tapped hole is clean and free of debris before threading in the screw. Do not apply excessive torque or use tools that could damage the head or strip the threads. Always confirm the thread specification of the mating component matches 5/16-18 UNC before installation.
