Itw Buildex 560050 Self Drilling Screw 1/4-14 X 3/4 in 100pk

Product Description

The ITW BUILDEX 560050 is a 1/4-14 self drilling screw designed for fast, reliable fastening in steel framing and sheet metal applications. The hex washer head provides a broad bearing surface, and the built-in 3-point drill tip eliminates the need for a pre-drilled pilot hole. Fabricated from steel, these screws are suited for trade professionals working on metal-to-metal connections in HVAC ductwork, light gauge steel framing, and similar structural assemblies. Each package contains 100 screws with a thread pitch of 14 threads per inch and a 3/4-inch length under head.

These screws are commonly used by HVAC technicians, sheet metal fabricators, and commercial construction crews fastening light gauge steel components. The hex washer head and hex drive provide positive engagement under torque, reducing cam-out during installation. Typical applications include ductwork assembly, metal stud framing, and equipment panel attachment where fast self-drilling performance is required without pre-drilling.

Key Features

• 3-point drill tip drills its own pilot hole, eliminating pre-drilling steps
• 1/4-14 thread size provides strong thread engagement in light gauge steel
• Hex washer head delivers a wide bearing surface to resist pull-through
• Hex drive type allows positive torque transfer and reduces cam-out
• Steel construction for durability in metal fastening applications
• Sold in a 100-count package for jobsite and shop use

Compatibility

Designed as an OEM-style replacement and standard fit for light gauge steel framing, sheet metal ductwork, and metal panel fastening applications requiring a 1/4-14 self drilling screw with a hex washer head.

Installation Notes

Installation is performed using a hex driver or impact driver set to a controlled torque to avoid overdriving and stripping threads. Confirm the base material gauge is within the rated range for the 3-point drill tip before installation. Do not exceed recommended drive speed, as excessive RPM can cause tip heat buildup and reduce drilling performance. Follow applicable building or mechanical codes for fastener spacing and pull-out requirements in structural and HVAC applications.
