Value Collection R63283282 Thumb Screw 1/4-20 Oval Head

Product Description

The VALUE COLLECTION R63283282 is an 18-8 stainless steel thumb screw with a 1/4-20 UNC thread and an oval head profile. It is designed for hand-tightening applications where tools are not practical or where frequent removal is required. The oval head measures 0.55 inches in diameter and 0.64 inches in height, providing a comfortable grip surface. At 1 inch overall length, this fastener suits a wide range of light-duty assembly tasks. The 18-8 stainless steel construction offers corrosion resistance suitable for general industrial, marine-adjacent, and outdoor enclosure applications. No shoulder is present on this design, making it a straightforward through-hole or tapped-insert fastener.

This thumb screw is appropriate for use in control panels, enclosures, jigs, fixtures, and equipment covers where hand-operable fasteners are preferred. It is commonly installed in light manufacturing, electrical enclosure assembly, HVAC equipment panels, and instrumentation housings. The 1/4-20 UNC thread is one of the most widely used coarse-thread standards in inch-system fastener applications, making this screw broadly compatible with standard tapped holes and inserts across many industries.

Key Features

• 1 inch overall length fits a broad range of panel and enclosure thicknesses

Compatibility

Designed as a standard inch-system thumb screw for use in any application with a 1/4-20 UNC tapped hole or insert requiring a hand-operable oval-head fastener.

Installation Notes

This fastener is installed by hand into a pre-tapped 1/4-20 UNC hole or threaded insert. Ensure the mating thread is clean and free of debris before installation. Do not use power tools to drive this thumb screw, as the oval head is not designed for tool torque and thread damage or head deformation may result. If used in an electrical enclosure, follow applicable NEC guidelines for panel access and fastener requirements.
