Itw Buildex 560073 Self Drilling Screw No. 12 2-3/4 in 100pk

Product Description

The ITW BUILDEX 560073 is a No. 12 self drilling screw designed for metal-to-metal and metal-to-substrate fastening applications across HVAC, mechanical, and light construction trades. It features a flat head profile with a Phillips drive and a No. 4 drill point that cuts its own pilot hole on contact, eliminating the need for a separate drilling step. The overall length is 2-3/4 inches, and the thread specification is No. 10-24. Manufactured from steel, this fastener delivers consistent thread engagement and point performance in sheet metal and structural panel work. Sold in a pack of 100.

Self drilling screws of this type are commonly used in HVAC ductwork assembly, electrical enclosure fabrication, metal framing, and mechanical equipment installation. The flat head seats flush with the work surface, making this screw well suited for applications where a low-profile fastening face is required. The Phillips drive is compatible with standard power drivers and hand tools used in the field. The No. 4 drill point is rated for thicker gauge material than a No. 2 point, making it appropriate for heavier sheet metal work typical in commercial and light industrial settings.

Key Features

• No. 4 drill point self-taps through heavier gauge sheet metal without a pre-drilled pilot hole
• Flat head profile seats flush for low-profile installations
• Phillips drive compatible with standard power drivers used in the field
• No. 10-24 thread pitch provides reliable thread engagement in steel substrates
• 2-3/4 inch overall length suits deeper fastening requirements in metal panel and duct work
• Steel construction for durability in mechanical and HVAC applications

Compatibility

Designed as a standard self drilling fastener for metal-to-metal and metal-to-light-gauge-structural applications common in HVAC ductwork, electrical enclosures, and mechanical equipment assemblies requiring a flush-seating flat head fastener.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or electricians using a standard Phillips bit and power driver set to appropriate torque to avoid overdriving the flat head. Ensure material gauge is within the rated capacity of the No. 4 drill point before driving. Power down any energized equipment or ductwork systems before fastening into enclosures or panels. Avoid backing out and re-driving self drilling screws, as this degrades thread engagement in the base material.
