Value Collection R63283224 Thumb Screw 1/4-20 Oval Head

Product Description

The VALUE COLLECTION R63283224 is an 18-8 stainless steel thumb screw with an oval head profile and a 1/4-20 UNC thread form. It measures 1.5 inches in overall length and features a head diameter of 0.55 inches and a head height of 0.64 inches. The wingless, knurled-style oval head allows hand-tightening without tools in applications where frequent access or adjustment is required. Fabricated from 18-8 stainless steel, the fastener resists corrosion in moist or mildly chemical environments, making it a practical choice for panel covers, access doors, and equipment enclosures in HVAC, electrical, and plumbing service settings.

This thumb screw is suited for light-duty fastening tasks where tool-free removal and reinstallation are priorities. Typical applications include securing inspection panels, junction box covers, equipment guards, and instrument housings. The 1/4-20 UNC thread is one of the most common coarse-thread inch-series standards, so the fastener mates with a wide range of tapped holes, threaded inserts, and wing nuts already found in trade equipment and service enclosures. The without-shoulder design keeps the thread engagement full along the entire grip length.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in damp or mildly corrosive service environments
• Oval head profile allows hand-tightening and removal without a screwdriver or wrench
• 1/4-20 UNC thread standard for broad compatibility with inch-series tapped components
• 1.5-inch overall length suits standard panel and cover fastening applications
• Without-shoulder design maximizes usable thread engagement along the full body length

Compatibility

Designed as a standard inch-series thumb screw for use in any application accepting a 1/4-20 UNC thread, including tapped holes, threaded inserts, and hex nuts in equipment panels and enclosures.

Installation Notes

Hand-tighten only to the resistance appropriate for the application — do not use a wrench or driver on the oval head, as doing so can damage the head profile or over-torque the joint. Verify thread engagement depth in the mating component before final assembly. Shut down and de-energize any electrical equipment before removing or replacing panel fasteners. Follow applicable NEC or local electrical code requirements when working inside energized enclosures.
