Value Collection HWTCIF02500500US-050B Thread Cutting Screw

Product Description

The VALUE COLLECTION HWTCIF02500500US-050B is a 1/4-20 UNC thread cutting screw designed for fastening into pre-drilled or punched holes in metal without requiring a pre-tapped thread. The hex head accepts a standard hex driver or wrench for reliable torque application. Constructed from Grade 2 steel with a zinc-plated finish, this screw resists corrosion in typical indoor and light-duty industrial environments. The Type F point features a tapered end with cutting flutes that form mating threads as the fastener is driven, making it well suited for sheet metal assemblies, HVAC ductwork, electrical enclosures, and similar light-gauge metal applications. The under-head length measures 1/2 inch with a 1/4-20 thread pitch.

This screw is commonly used in residential and commercial trade work where a self-threading metal fastener is needed in thin-gauge steel panels, brackets, or enclosures. HVAC technicians, electricians, and sheet metal workers reach for Type F thread cutting screws when joining metal components that do not have pre-formed internal threads. The 1/4-20 UNC thread standard ensures broad compatibility with standard tooling and hardware used across mechanical, electrical, and HVAC installations. This SKU ships in a minimum order quantity of 50 pieces per order.

Key Features

• Type F point with cutting flutes forms internal threads in pre-drilled or punched metal holes
• 1/4-20 UNC thread size for broad tooling compatibility
• 1/2 inch under-head length for light-gauge metal fastening
• Hex head design accepts standard hex wrenches and nut drivers
• Grade 2 steel construction provides adequate tensile strength for general-duty applications
• Zinc-plated finish provides corrosion resistance in typical indoor service environments

Compatibility

Designed as a standard 1/4-20 UNC Type F thread cutting screw suitable for use in light-gauge steel panels, HVAC ductwork, electrical enclosures, and general sheet metal assemblies where a self-threading fastener is required.

Installation Notes

Installation is performed by trade professionals including HVAC technicians, electricians, and sheet metal workers using a hex driver or wrench sized to the hex head. A correctly sized pilot hole must be drilled or punched in the receiving material prior to driving the screw to allow the Type F cutting flutes to form threads cleanly without splitting the workpiece. De-energize and lock out any electrical or mechanical equipment before fastening into enclosures or panels. Do not overdrive — apply consistent torque until the head seats flush against the mating surface.
