Value Collection R63280286 Thumb Screw 5/16-18 Oval Head

Product Description

The VALUE COLLECTION R63280286 is an 18-8 stainless steel thumb screw with an oval head and integral shoulder, designed for hand-tightened fastening applications where tools are not required or practical. Threaded to a 5/16-18 UNC standard, this screw delivers reliable corrosion resistance from its 18-8 stainless steel construction, making it suitable for both indoor and outdoor environments. The oval head measures 0.7 inches in diameter and 0.78 inches in height, providing a comfortable grip surface. Overall length is 1 inch. Technicians, assemblers, and maintenance professionals working in mechanical, industrial, or trade service applications will find this fastener suited for quick-access panels, enclosures, and adjustable assemblies.

This thumb screw is used in applications requiring frequent hand adjustment or removal without tooling. The shoulder design helps locate the screw accurately within a counterbored hole or mating part, preventing lateral movement during installation. Typical applications include equipment access panels, jigs, fixtures, and light mechanical assemblies across industrial and trade service environments where stainless steel corrosion resistance is specified.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments
• 5/16-18 UNC thread standard for broad compatibility with standard inch-system hardware
• Oval head profile with shoulder design aids in precise seating and hand grip
• Head diameter of 0.7 inches and head height of 0.78 inches for comfortable manual operation
• 1 inch overall length suits shallow-panel and light-duty fastening tasks
• No tools required for installation or removal, reducing service time on access assemblies

Compatibility

Designed as a standard inch-system thumb screw compatible with 5/16-18 UNC threaded holes in panels, enclosures, fixtures, and mechanical assemblies requiring hand-tool-free fastening.

Installation Notes

Installation is performed by hand threading into a pre-tapped 5/16-18 UNC hole. Ensure mating threads are clean and free of debris before installation. Do not use a driver or wrench to overtighten, as thumb screws are intended for hand-torque only. Inspect threads periodically in corrosive or high-vibration environments to confirm secure seating.
