Value Collection R63288222 Brass Thumb Screw 3/8-16

Product Description

The VALUE COLLECTION R63288222 is a brass thumb screw with a 3/8-16 UNC thread and an oval head profile, intended for hand-tightening applications where tools are not practical or permitted. The screw measures 1.5 inches in overall length, with a head diameter of 0.83 inches and a head height of 0.95 inches. Machined from brass, it offers natural corrosion resistance and is suited for use in assemblies where galling or galvanic concerns rule out steel fasteners. Plumbers, electricians, panel builders, and general tradespeople install this type of fastener in enclosures, access covers, and equipment panels.

This thumb screw is appropriate for residential and light commercial applications where frequent hand-access is needed without tooling. Typical install scenarios include instrument panels, junction box covers, equipment access doors, and fixture assemblies. The 3/8-16 UNC thread is a common coarse-thread standard, making this screw widely compatible with tapped holes in standard steel, aluminum, and brass components.

Key Features

• Brass construction provides corrosion resistance and prevents galling in metal assemblies
• 3/8-16 UNC coarse thread for broad compatibility with standard tapped components
• Oval head profile allows comfortable hand-tightening without tools
• 0.83-inch head diameter and 0.95-inch head height provide solid grip surface
• 1.5-inch overall length suits medium-depth panel and enclosure applications
• No-shoulder design for flush or near-flush seating against mating surfaces

Compatibility

Designed as an OEM-style replacement or standard-stock thumb screw for assemblies using 3/8-16 UNC tapped holes in metal enclosures, panels, and equipment covers.

Installation Notes

This fastener is installed by hand in pre-tapped 3/8-16 UNC holes. De-energize or shut down any equipment before servicing panels or enclosures where this screw is used. Do not over-torque brass fasteners with tools, as the material is softer than steel and threads may strip. Verify thread engagement depth is adequate for the application before placing the assembly into service.
