Value Collection R63283485 Thumb Screw 5/16-18 Oval Head

Product Description

The VALUE COLLECTION R63283485 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 where tools are not practical or desirable, this fastener is commonly used in equipment panels, enclosures, access covers, and assemblies that require frequent removal or adjustment. The 18-8 stainless steel construction resists corrosion in general-purpose indoor and light outdoor environments. At 2 inches in overall length, this screw suits a range of standard panel thicknesses. The oval head measures 0.7 inches in diameter and 0.78 inches in height, providing a comfortable grip surface for manual operation. Installed by mechanical technicians, electricians, and field service personnel across HVAC, electrical, and general equipment maintenance.

This thumb screw is suited for use in residential and light commercial equipment enclosures, junction boxes, instrument panels, and maintenance access covers where hand-operated fasteners are specified. It is a standard inch-series fastener following UNC thread standards, making it compatible with tapped holes and standard hex nuts of the matching 5/16-18 thread size. The without-shoulder design allows full thread engagement along the fastener shank. Applications span HVAC equipment panels, electrical enclosures, and industrial machinery covers that see routine service access.
