Itw Buildex 560089 Self Drilling Screw 12-24 100 Pack

Product Description

The ITW BUILDEX 560089 is a 12-24 self drilling screw designed for fastening into steel framing, metal panels, and similar structural materials. The hex washer head and hex drive allow for reliable torque transfer using standard hex bit drivers. At 2 inches in length under the head and featuring a 5-point drill tip, this screw is built to penetrate and tap its own hole in one operation without pre-drilling. The stainless steel head paired with a steel body provides corrosion resistance at the exposed surface while maintaining overall strength. Sold in a 100-piece package, these screws are suited for high-volume commercial and light-gauge metal construction work.

These self drilling screws are commonly used in metal-to-metal fastening applications including HVAC duct assembly, metal stud framing, roofing, and curtain wall installation. The 5-point drill point is designed for heavier gauge steel penetration. The hex washer head seats flush against the material surface, distributing load and resisting pull-through. Trades including HVAC sheet metal workers, commercial framers, and roofing contractors regularly use this fastener type in both new construction and retrofit projects.

Key Features

• 12-24 thread size for secure metal-to-metal engagement
• 5-point drill tip for self-starting penetration into heavier gauge steel
• Hex washer head with hex drive for positive bit engagement and load distribution
• 2-inch length under head suits a range of material stack thicknesses
• Stainless steel head with steel body balances corrosion resistance and structural strength
• 100-piece package quantity for job-site and shop use

Compatibility

Designed as an OEM-style replacement and general-use self drilling screw for metal-to-metal fastening applications in light-gauge steel construction and mechanical systems assembly.

Installation Notes

Self drilling screws of this type are installed using a hex-drive bit with an adjustable-clutch screw gun or impact driver set to appropriate torque. Ensure material thickness is within the rated capacity of the 5-point drill tip before driving. Follow applicable codes including AISI framing standards and local building code requirements for fastener spacing and pattern. Inspect finished fastener heads for proper seating and avoid overdriving, which can strip the thread engagement or deform the washer flange.
