Value Collection R63283443 Thumb Screw 5/16-18 Oval Head

Product Description

The VALUE COLLECTION R63283443 is an 18-8 stainless steel thumb screw with a 5/16-18 UNC thread and an oval head profile. Designed for hand-tightening applications, it allows for tool-free fastening and removal in assemblies where frequent access or adjustment is required. The 18-8 stainless steel construction provides solid corrosion resistance in moderate-exposure environments. With a 1.0-inch overall length, a head diameter of 0.7 inches, and a head height of 0.78 inches, this fastener suits panel mounting, enclosure access points, jigs, and fixture builds where a low-profile oval head and repeatable hand torque are practical requirements.

This thumb screw is suited for light to medium-duty fastening tasks across electrical, mechanical, and general trade applications. Its without-shoulder design seats flush to the mating surface and works with standard 5/16-18 UNC threaded inserts, nuts, and tapped holes. Typical applications include equipment panels, enclosure covers, control boxes, and shop fixtures where hand-operable fasteners improve service workflow without specialized tooling.

Key Features

• 18-8 stainless steel construction for corrosion resistance in moderate-exposure settings
• 5/16-18 UNC thread for compatibility with standard inch-series tapped holes and inserts
• Oval head profile with 0.7-inch head diameter for secure finger grip
• Without-shoulder design for flush, full-thread engagement
• 1.0-inch overall length suits standard panel and enclosure fastening depths
• Sold individually for single-unit replacement or low-quantity applications

Compatibility

Designed for use in standard 5/16-18 UNC threaded holes, inserts, and nuts across general mechanical and electrical enclosure assemblies.

Installation Notes

Installation is hand-tightening only — no tools required under normal service conditions. Verify the mating thread is clean and free of debris before seating the fastener. Do not exceed hand torque when tightening, as over-torquing can damage the knurled head or strip the thread. Stainless-to-stainless galling is possible; apply a thin thread lubricant if torque resistance is encountered.
