Itw Buildex 560061 Self Drilling Screw 1/4-28 3in 100pk

Product Description

The ITW BUILDEX 560061 is a self drilling screw designed for metal-to-metal and structural fastening applications in commercial and industrial construction. It features a hex washer head driven by a 7/16-inch hex driver, a 1/4-28 unified fine thread, and a No. 5 drill point that eliminates the need for a pre-drilled pilot hole. At 3 inches length under head, this screw is suited for fastening thicker steel assemblies where a standard short point would fail to penetrate cleanly. Sold in a pack of 100, it is a go-to choice for sheet metal work, metal framing, and steel deck attachment.

This screw is used in commercial construction, metal building erection, and industrial fabrication where self-drilling capability into heavier-gauge steel is required. The No. 5 drill point is rated for penetrating thicker steel sections without a pilot hole, making it appropriate for structural steel connections, purlins, girts, and similar framing members. Licensed sheet metal contractors, ironworkers, and structural steel crews are the typical installers of this fastener type.

Key Features

• No. 5 drill point drills its own pilot hole in heavier-gauge steel without pre-drilling
• 1/4-28 unified fine thread for secure engagement in steel substrates
• Hex washer head provides a built-in bearing surface and resists pull-through
• Hex drive accepts a standard 7/16-inch hex driver bit or impact driver socket
• 3-inch length under head accommodates thicker steel assemblies and multi-layer connections
• Steel construction for structural-grade strength and durability
• 100-piece package quantity supports production-volume work

Compatibility

Designed as an OEM-style self drilling fastener for metal-to-metal structural and cladding applications requiring a 1/4-28 thread and No. 5 drill point in heavy-gauge steel.

Installation Notes

Installation is performed by licensed sheet metal contractors, ironworkers, or structural crews using a hex driver bit or impact driver set to a controlled clutch setting to avoid over-driving and stripping the hex washer head. De-energize any adjacent electrical systems and follow applicable OSHA fall protection requirements when installing at elevation. Do not over-torque; the hex washer head bearing surface should seat flush without deforming the substrate. Consult applicable building codes and structural drawings for required fastener spacing and edge distances.
