Value Collection R63280242 Thumb Screw 1/4-20 Oval Head

Product Description

The VALUE COLLECTION R63280242 is an 18-8 stainless steel thumb screw with a 1/4-20 UNC thread and an oval head profile. Designed for hand-tightening applications, this thumb screw features a shouldered shank that provides a positive seating surface when fully engaged. At 1 inch overall length, it is sized for light-duty fastening tasks where tool-free adjustability is required. The 18-8 stainless steel construction provides corrosion resistance suitable for general industrial, marine-adjacent, and outdoor enclosure applications. Electricians, HVAC technicians, and panel fabricators commonly use oval-head thumb screws for access covers, inspection panels, and equipment housings that require frequent removal.

This thumb screw is suited for use in control panel assembly, electrical enclosure covers, HVAC equipment access doors, and similar light-duty fastening scenarios where hand-tightened fasteners are appropriate. The 1/4-20 UNC thread is one of the most common coarse-thread standards in inch-measurement systems, making this fastener compatible with a wide range of tapped holes and threaded inserts found in standard sheet metal and machined components across residential and light commercial trade applications.

Key Features

• 18-8 stainless steel construction for corrosion resistance in damp or outdoor-adjacent environments
• Oval head profile provides a smooth, low-profile grip surface for hand tightening
• Shouldered shank design offers positive seating when fastener is fully driven
• 1/4-20 UNC thread standard for broad compatibility with tapped holes and threaded inserts
• 1 inch overall length suits standard panel and enclosure cover thicknesses

Compatibility

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

Installation Notes

Hand-tighten only — do not drive with power tools, as overtorquing will damage the thumb screw head or strip the mating threads. Ensure the mating tapped hole or threaded insert is clean and free of debris before installation. Always de-energize electrical panels or equipment before servicing access covers secured with thumb screws. Stainless fasteners can gall against stainless threads — apply an anti-seize compound if the fastener will be removed frequently.
