Itw Buildex 560032 Self Drilling Screw No.12 100 Pack

Product Description

The ITW BUILDEX 560032 is a No. 12 self drilling screw designed for fast, reliable fastening in steel construction and metal fabrication applications. It features a hex washer head with a hex drive and a No. 3 drill point that cuts its own pilot hole, eliminating the need for pre-drilling. The thread size is No. 12-14, meaning 14 threads per inch, and the length under the head is 1 inch. Each package contains 100 screws. This fastener is installed by HVAC technicians, sheet metal workers, and general contractors working with light-gauge steel assemblies.

This screw is suited for attaching sheet metal panels, ductwork components, metal brackets, and similar light-gauge steel materials. The No. 3 drill point is rated for piercing thicker gauges of steel compared to smaller point sizes, making it appropriate for moderate-thickness metal-to-metal connections. It is commonly used in residential and light commercial HVAC duct fabrication, metal framing, and electrical enclosure assembly where a secure, vibration-resistant mechanical connection is required.

Key Features

• No. 3 drill point self-drills through light- to moderate-gauge steel without a pilot hole
• No. 12-14 thread size provides strong thread engagement in steel substrates
• Hex washer head with hex drive allows high torque application and positive bit engagement
• 1-inch length under head suits standard sheet metal and thin panel fastening tasks
• Steel construction for durability in metal assembly applications
• Sold in a 100-count package for jobsite-ready quantities

Compatibility

Designed as a standard No. 12 self drilling screw for use in light-gauge steel-to-steel fastening applications common in HVAC duct fabrication, metal framing, and sheet metal panel assembly.

Installation Notes

Install with a hex-drive bit and a variable-speed screw gun or drill to control penetration depth and avoid stripping the head. Power down any electrical equipment and de-energize ductwork systems before fastening near live components. Follow applicable sheet metal fabrication standards and local mechanical codes when assembling ductwork or structural metal panels. Do not overdrive — seat the washer head flush against the material surface without compressing it excessively.
