Itw Buildex 560043 Self Drilling Screw No.12 250 Pack

Product Description

The ITW BUILDEX 560043 is a No. 12 self-drilling screw designed for fast, reliable fastening in steel construction and sheet metal applications. It features a hex washer head with a hex drive and a 4-point drill tip that eliminates the need for a pilot hole. The screw measures 7/8 inches in length under the head and carries a No. 12-24 thread specification. Each package contains 250 screws. This fastener is installed by HVAC sheet metal workers, electricians, and general contractors working with light-gauge steel framing, ductwork, and metal panels.

This screw is well suited for light-gauge steel-to-steel fastening in residential and commercial construction environments. Common applications include HVAC duct assembly, metal stud framing, electrical enclosure attachment, and roof deck fastening. The 4-point drill tip improves penetration speed and reduces cam-out during installation. The hex washer head provides a broad bearing surface that distributes clamping load across the workpiece. The 250-count package is sized for production work and service van stocking.

Key Features

• 4-point self-drilling tip eliminates the need for a pilot hole in light-gauge steel
• Hex washer head delivers a wide bearing surface for consistent clamping
• Hex drive reduces cam-out and improves torque transfer at the driver
• No. 12-24 thread pitch engineered for steel-to-steel engagement
• 7/8-inch length under head suits thin-material stack-ups common in ductwork and framing
• 250-piece package supports high-volume production and service use

Compatibility

Designed as an OEM-style self-drilling fastener for light-gauge steel applications including sheet metal ductwork, metal framing, and electrical enclosures where a No. 12 hex washer head screw is specified.

Installation Notes

Installation requires a hex-drive bit and a variable-speed drill or screw gun set to an appropriate clutch setting for light-gauge steel. Secure the workpieces together before driving to prevent movement during penetration. Follow applicable building codes such as the AISI standards for cold-formed steel framing when used in structural applications. Do not overdrive — the hex washer head flange should seat flush without deforming the substrate.
