Itw Buildex 560129 Self Drilling Screw 1/4 in Pack of 100

Product Description

The ITW BUILDEX 560129 is a 1/4 inch self drilling screw designed for fast, reliable fastening without a pre-drilled pilot hole. Featuring a hex washer head with a hex drive, this screw delivers consistent torque transfer and a broad bearing surface under the head. The 3-point drill point cuts cleanly through steel substrates, reducing installation time on the job. With a 1-1/2 inch length measured under the head and a 1/4-14 thread size, it is well suited for light-gauge steel framing, HVAC ductwork attachment, and general sheet metal assembly work.

This screw is commonly used in residential and commercial construction and mechanical trades. HVAC technicians reach for self drilling screws when securing duct sections, hanging equipment, or fastening sheet metal panels where speed and holding strength matter. The hex washer head seats flush against the material surface, distributing load and resisting pull-through. Each package contains 100 screws, making it practical for both single-trade service calls and larger installation projects.

Key Features

• 1/4-14 thread size for secure engagement in light-gauge steel
• 3-point drill point penetrates steel without a pilot hole
• Hex washer head provides a wide bearing surface and reduces pull-through
• Hex drive allows high torque input with standard hex bit drivers
• 1-1/2 inch length under head suits typical sheet metal and light framing applications
• Steel construction for durability in mechanical and structural fastening

Compatibility

Designed as an OEM-style replacement and general-use self drilling screw for light-gauge steel fastening applications common in HVAC ductwork, sheet metal work, and steel framing assembly.

Installation Notes

Installation is performed by HVAC technicians, sheet metal workers, and general contractors using a hex bit driver or nut driver set to appropriate speed. Power down and de-energize any electrical or mechanical equipment in the work area before fastening near live components. Use a variable-speed drill or screw gun to control penetration speed and avoid stripping the drive recess or overdriving the head. Verify that substrate material thickness is within the rated capacity of a number 3 drill point before installation.
