Itw Buildex 560038 Self Drilling Screw No. 12 100 Pack

Product Description

The ITW BUILDEX 560038 is a No. 12 self drilling screw designed for fast, reliable fastening in steel and metal construction applications. Featuring a hex washer head with a hex drive, this screw combines clamping surface coverage with the torque control of a standard hex bit. The No. 3 drill point eliminates the need for a pilot hole, allowing the screw to cut through material in a single step. At 2.5 inches length under head and a thread pitch of 14 threads per inch, it delivers solid thread engagement in structural and sheet metal assemblies. Sold in a 100-count package, it suits both service truck stocking and job site use.

This screw is used in light-gauge steel framing, metal roofing, HVAC ductwork attachment, and general sheet metal fabrication. It is well suited for residential and commercial construction projects where a clean, driven fastener is needed without pre-drilling. HVAC sheet metal installers, steel framing contractors, and general trade professionals are the primary installers of this type of fastener. The hex washer head seats flush against the material surface, distributing load and reducing the risk of pull-through on thinner gauge stock.

Key Features

• No. 3 drill point self-taps through steel without a pilot hole
• Hex washer head provides a wide bearing surface to reduce pull-through
• Hex drive compatible with standard 5/16-inch hex bit drivers
• No. 12-14 thread size with 14 threads per inch for strong thread engagement
• 2.5-inch length under head suits moderate-depth fastening applications
• 100-count package supports both single-job and stock replenishment use

Compatibility

Designed as an OEM-style replacement and general-use fastener for No. 12 self drilling screw applications in light-gauge steel framing, metal roofing, and HVAC sheet metal assemblies.

Installation Notes

Installation is performed by sheet metal workers, steel framers, and HVAC technicians using a standard hex-drive bit or nut driver. Ensure the drill point is aligned perpendicular to the work surface before driving to prevent walking or cam-out. Do not overdrive — the hex washer head should seat firmly against the material without deforming the substrate. Follow applicable building codes and manufacturer guidelines for fastener spacing in structural applications.
