Value Collection R63280441 Thumb Screw 3/8-16 Oval Head

Product Description

The VALUE COLLECTION R63280441 is an 18-8 stainless steel thumb screw with a 3/8-16 UNC thread and an oval head profile. It is designed for hand-tightened fastening applications where tools are not required or practical. The shoulder-style body provides positive seating against mating surfaces. At 1.5 inches overall length, with a head diameter of 0.83 inches and a head height of 0.95 inches, this thumb screw suits panel assemblies, enclosures, jigs, and fixtures in industrial and trade settings. Machinists, maintenance technicians, and fabricators typically install this fastener where frequent removal and reinstallation is expected.

This thumb screw is suited for light industrial, manufacturing, and general mechanical assembly applications. The oval head style provides a smooth, rounded grip surface for comfortable hand actuation. The with-shoulder construction helps align and retain panels or components during assembly. Typical use cases include equipment access panels, guard covers, and fixture mounting in workshop or field environments where hand-tightened fastening is preferred over tool-driven hardware.

Key Features

• 18-8 stainless steel construction resists corrosion in wet or mildly corrosive environments
• 3/8-16 UNC thread for broad compatibility with standard inch-system tapped holes
• Oval head profile provides comfortable grip for repeated hand tightening and loosening
• With-shoulder design supports accurate component seating and alignment
• 1.5 inch overall length suits medium-depth panel and fixture fastening applications

Compatibility

Designed as a standard inch-system thumb screw for use in any 3/8-16 UNC tapped hole where an oval-head, hand-actuated fastener with shoulder is required.

Installation Notes

Installation is performed by hand without tools in most applications. Ensure the mating tapped hole is clean and free of debris before threading the screw in. Do not use a wrench or driver on the head, as the oval profile is not designed for tool torque and may deform. Where vibration is present, consider a locking insert or thread-locking compound appropriate to the assembly.
