Value Collection 31839 1/4-20 Unc Hex Thread Cutting Screw 50pk

Product Description

The VALUE COLLECTION 31839 is a 1/4-20 UNC hex head thread cutting screw designed for creating mating threads in pre-drilled holes in metal and other hard materials. This Type F point style features a tapered end with cutting edges that displace material as the fastener is driven, eliminating the need for a pre-tapped hole. Built from Grade 2 steel with a zinc-plated finish, it delivers solid corrosion resistance for general-purpose indoor and light industrial applications. The 3/4-inch length under head suits a range of sheet metal, structural, and fabrication tasks. Sold in a pack of 50, this fastener is a standard choice for production assembly, maintenance, and repair work.

This screw is suited for use in light to medium fabrication scenarios where threading into unthreaded base material is required. The hex head drive allows for high torque application using a nut driver, socket wrench, or hex bit, making it practical on production lines and service calls alike. Typical applications include metal-to-metal fastening in HVAC equipment panels, electrical enclosures, light structural assemblies, and general sheet metal work. The zinc plating provides a baseline level of corrosion protection appropriate for dry or lightly humid indoor environments.

Key Features

• Type F point cuts threads directly into pre-drilled holes, no tapping required
• Hex head drive accepts standard nut drivers, sockets, and hex bits for high-torque installation
• Grade 2 steel construction provides adequate strength for general-purpose fastening applications
• Zinc-plated finish offers corrosion resistance suitable for dry indoor environments
• 1/4-20 UNC thread standard for broad compatibility with standard tooling and hardware
• Pack of 50 supports production, service, and maintenance workflow efficiency

Compatibility

Designed as a general-purpose thread cutting fastener for use in metal panels, enclosures, and light structural assemblies where a 1/4-20 UNC thread is specified.

Installation Notes

Installation should be performed with a properly sized nut driver, socket, or hex bit to avoid fastener damage. Ensure the base material is pre-drilled to the correct pilot hole diameter for a 1/4-20 Type F thread cutting screw before driving. Do not overtorque, as Grade 2 steel has lower tensile strength than higher-grade fasteners. Follow applicable mechanical and structural codes for the assembly type being fastened.
