Value Collection C24028 1/4-20 Unc Thread Cutting Screw 50-pack

Product Description

The VALUE COLLECTION C24028 is a 1/4-20 UNC thread cutting screw designed for reliable fastening in metal and other hard materials where threads are cut during installation. Featuring a pan head profile and Phillips drive, this screw accepts standard Phillips bits for quick installation with common power tools. The Type F point is engineered to cut clean threads in pre-drilled or punched holes, reducing the need for tapping. Finished with zinc plating for basic corrosion resistance, the C24028 is suited for light industrial, HVAC sheet metal, electrical enclosure, and general maintenance applications. Each package contains 50 screws.

This screw is commonly used by HVAC technicians, electricians, and general maintenance professionals for securing panels, covers, junction boxes, and sheet metal assemblies. The 1/4-20 UNC thread and 3/4-inch under-head length make it appropriate for light-gauge metal fastening tasks where a self-threading fastener eliminates the need for a pre-tapped hole. Sold in packs of 50, it is practical for stocking a service vehicle or shop supply.

Compatibility

Designed as a general-purpose 1/4-20 UNC thread cutting fastener suitable for light-gauge metal panels, electrical enclosures, HVAC equipment covers, and similar sheet metal assemblies requiring a self-threading screw.

Installation Notes

Installation is typically performed by HVAC technicians, electricians, or maintenance professionals using a Phillips-tip screwdriver or power driver. Always de-energize electrical equipment and shut down HVAC systems before removing or replacing fastened panels or covers. Ensure the receiving material is pre-drilled or punched to the correct pilot hole diameter for a 1/4-20 thread cutting screw before driving. Do not overtighten, as thread cutting screws in light-gauge metal can strip the formed threads if excessive torque is applied.
