Itw Buildex 560046 Self Drilling Screw No.12 100 Pack

Product Description

The ITW BUILDEX 560046 is a No. 12 self drilling screw designed for fast, reliable fastening in metal-to-metal and metal-to-substrate applications. Featuring a hex washer head and hex drive, this screw drills its own pilot hole and taps its own thread, eliminating the need for pre-drilling. The No. 5 drill point handles heavier gauge steel efficiently. At 1.5 inches in length under head with a 12-24 thread pitch, this screw is a standard workhorse for sheet metal fabrication, HVAC ductwork assembly, electrical enclosure installation, and structural metal framing. Sold in a 100-piece package.

This screw is commonly used by HVAC technicians, electricians, and sheet metal workers in both residential and light commercial applications. Typical uses include securing duct sections, fastening electrical panel components, attaching metal brackets, and general structural metal assembly where a self-tapping, self-drilling fastener is required. The hex washer head provides a broad bearing surface that resists pull-through, and the hex drive allows for reliable power-tool installation with a standard nut driver or hex bit.

Key Features

• No. 5 drill point self-drills through steel without pre-drilling
• 12-24 thread pitch provides strong thread engagement in metal substrates
• Hex washer head delivers broad bearing surface to resist pull-through
• Hex drive compatible with standard nut drivers and hex bits for fast power-tool installation
• Steel construction for durability in structural and HVAC fastening applications
• Packaged in quantities of 100 for job-site efficiency

Compatibility

Designed as a standard No. 12 self drilling screw suitable for metal-to-metal and metal-to-light-gauge-steel fastening applications in HVAC, electrical, and general sheet metal work.

Installation Notes

Install using a power driver fitted with a hex bit or nut driver matched to the hex head size. Apply consistent, steady pressure to allow the drill point to engage the substrate before threads begin to cut. Power down all relevant electrical systems and relieve any duct pressure before fastening near energized equipment or pressurized ductwork. Refer to applicable mechanical and building codes for required fastener spacing and load ratings in structural applications.
