Value Collection R63288441 Brass Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION R63288441 is a brass thumb screw with an oval head profile and a 1/4-20 UNC thread. It is designed for hand-tightening applications where tools are not practical or necessary. The screw measures 1.5 inches in overall length, with a head diameter of 0.55 inches and a head height of 0.64 inches. Manufactured from brass, it offers corrosion resistance and is suitable for use in light mechanical assemblies, enclosures, access panels, and equipment covers. Electricians, HVAC technicians, and general tradespeople install these fasteners where frequent removal and re-installation is required.

This thumb screw is used in residential and commercial trade applications where finger-operated fastening is preferred. Common install scenarios include securing access panels on electrical enclosures, control boxes, and HVAC equipment covers. The 1/4-20 UNC thread is a widely used standard, making this fastener compatible with tapped holes in sheet metal, plastic, and machined aluminum assemblies encountered across HVAC, electrical, and plumbing service work.

Key Features

• Oval head profile allows comfortable finger grip for hand-tightening without tools
• 1/4-20 UNC thread standard for broad compatibility with common tapped holes
• Brass construction provides corrosion resistance in typical service environments
• 1.5 inch overall length suits standard panel and cover fastening applications
• Without-shoulder design for flush or near-flush seating against mating surfaces

Compatibility

Designed as a standard 1/4-20 UNC thumb screw for use in any application requiring a hand-tightened brass fastener with an oval head profile.

Installation Notes

Install by hand into a pre-tapped 1/4-20 UNC hole; no tools are required for normal seating. Ensure the mating thread is clean and free of debris before installation. Do not over-torque by using tools, as the brass material can be damaged by excessive force. Confirm thread engagement is sufficient for the application before returning equipment to service.
