Itw Buildex 560120 Self Drilling Screw No.12 100pk

Product Description

The ITW BUILDEX 560120 is a No. 12 self drilling screw designed for fast, clean fastening without a pre-drilled pilot hole. It features a hex washer head driven by a hex bit and carries a No. 2 drill point that cuts through steel and similar substrates in a single operation. The 1-1/2 inch length under head provides solid thread engagement in standard sheet metal and light structural applications. This screw is sold in a package of 100 and is a go-to fastener for HVAC sheet metal fabrication, metal framing, and light steel construction.

This screw is used in residential and light commercial applications where steel-to-steel or steel-to-substrate fastening is required. Common install scenarios include HVAC duct assembly, metal stud framing, roofing panel attachment, and equipment enclosure work. The hex washer head seats flush against the material surface, providing a broad bearing face that resists pull-through. Tradespeople working sheet metal, mechanical systems, or light structural steel will find this a standard production fastener.

Key Features

• No. 2 drill point self-drills through steel without a pilot hole
• Hex washer head provides a wide bearing surface and resists pull-through
• Hex drive accepts standard 5/16-inch hex bit drivers
• No. 12-14 thread size delivers strong thread engagement in steel substrates
• 1-1/2 inch length under head suits standard sheet metal and light structural fastening
• Steel construction for durability in mechanical and structural applications

Compatibility

Designed as an OEM-style replacement and general-use self drilling screw suited for steel-to-steel and steel-to-substrate fastening in HVAC, metal framing, and light structural assembly applications.

Installation Notes

Installation is performed by HVAC technicians, sheet metal workers, and general contractors using a power drill or impact driver fitted with a 5/16-inch hex bit. Ensure the driving speed is appropriate for the substrate thickness to prevent cam-out or drill point breakage. Do not overtorque hex washer head screws, as this can strip the head or crack the bearing flange. Follow applicable building codes and manufacturer guidelines for fastener spacing and load requirements.
