Itw Buildex 560025 Self-drilling Screw No.10 250pk

Product Description

The ITW BUILDEX 560025 is a No. 10 self-drilling screw designed for fast, reliable fastening in steel-to-steel and steel-to-substrate applications. Featuring a hex washer head with a hex drive, this screw eliminates the need for a pre-drilled pilot hole, reducing labor time on the job. The No. 3 drill point provides clean penetration through light-gauge steel framing and sheet metal. The 1.5-inch length is measured under the head. Thread pitch is 16 threads per inch on a No. 10-16 thread form. Sold in a 250-count package, this fastener is built for high-volume commercial and industrial work.

This screw is commonly used in HVAC duct fabrication, light-gauge steel framing, electrical enclosure assembly, and general sheet metal work. The No. 3 drill point is suited for penetrating thicker gauge steel than a No. 2 point, making it a preferred choice where structural integrity and pull-out resistance matter. HVAC technicians, sheet metal workers, and electricians regularly specify this fastener for securing duct sections, panel boxes, and metal components in both residential and commercial installations.

Key Features

• No. 10-16 thread form with 16 threads per inch for strong thread engagement in steel
• No. 3 drill point drills and taps in a single step — no pilot hole required
• Hex washer head with hex drive for high torque application and positive bit engagement
• 1.5-inch length under head suits a range of light-to-medium gauge steel applications
• Steel construction for durability in structural and mechanical fastening
• 250-count package supports high-volume jobsite and shop use

Compatibility

Designed as an OEM-style self-drilling fastener for light-gauge steel framing, sheet metal ductwork, and metal panel assemblies where a No. 10-16 thread and No. 3 drill point are specified.

Installation Notes

Install with a hex-drive bit using a variable-speed screw gun or drill-driver — do not overdrive, as this can strip the thread or damage the substrate. Power down any energized electrical panels or equipment before fastening into or near live assemblies. Follow applicable codes including SMACNA duct construction standards for HVAC applications. Wear appropriate eye protection when driving self-drilling screws into steel.
