Value Collection R52001032 1/4-20 Unc Thread Cutting Screw

Product Description

The VALUE COLLECTION R52001032 is a 1/4-20 UNC thread cutting screw designed for fastening into metal or other hard materials where a mating thread must be formed during installation. Built from 1016-1024 steel with a zinc-plated finish for corrosion resistance, this screw features a flat undercut head and a Type F point for controlled thread engagement. It measures 1/2 inch in overall length and is driven with a No. 3 Phillips driver. Manufactured to ASME B18.6.3, ASME B18.6.4, and SAE J933 standards, it is suited for production assembly and maintenance applications where thread reliability and consistent torque performance are required.

This screw is used in light manufacturing, HVAC equipment assembly, electrical enclosure fabrication, and general sheet metal work. The flat undercut head sits flush or near-flush against the fastened surface, reducing interference with mating components. The Type F point cuts a clean thread path on first drive, making it appropriate for applications where tapping a hole beforehand is not practical. Installation is typically performed by assembly technicians, electricians, and HVAC service professionals working with pre-drilled or punched holes in sheet metal panels and brackets.

Key Features

• 1/4-20 UNC thread form for reliable engagement in standard tapped or self-threaded holes
• Type F point cuts threads on installation, eliminating the need for a pre-tapped hole
• Flat undercut head provides a low-profile flush fit against the fastened surface
• Zinc-plated 1016-1024 steel construction for strength and corrosion resistance
• No. 3 Phillips drive for compatibility with standard Phillips drivers and bits
• Meets ASME B18.6.3, ASME B18.6.4, and SAE J933 standards

Compatibility

Designed as a standard 1/4-20 UNC thread cutting fastener suitable for sheet metal, light-gauge steel panels, and similar materials where the screw forms its own mating thread during installation.

Installation Notes

Install using a No. 3 Phillips driver or compatible bit. Ensure the base material hole diameter is appropriate for a 1/4-20 thread cutting application before driving the screw. Do not overdrive — overtorquing can strip the formed thread in thin material. Follow applicable assembly standards and equipment manufacturer guidelines when used in electrical enclosures or HVAC equipment panels.
