Itw Buildex 560093 Self Drilling Screw 1/4 in 100 Pack

Product Description

The ITW BUILDEX 560093 is a self-drilling screw designed for fast, reliable fastening without a pre-drilled pilot hole. Built with a stainless steel head and steel body, this screw combines corrosion resistance at the surface with the strength of a hardened steel shank. It features a 1/4-14 thread size, a Number 1 drill point, and measures 1-1/8 inches in length under the head. The hex washer head with hex drive allows for high-torque installation using a standard nut driver or impact driver. Sold in a package of 100, it suits production-volume applications in trade and light industrial settings.

This screw is commonly used in HVAC ductwork assembly, light-gauge steel framing, metal panel attachment, and similar sheet metal fabrication tasks. The Number 1 drill point is rated for thinner gauge material. The hex washer head provides a built-in bearing surface that distributes clamping load and reduces pull-through. HVAC installers, sheet metal workers, and general contractors regularly specify this fastener type for duct connections and metal-to-metal joining applications.

Key Features

• Self-drilling Number 1 point eliminates the need for a pilot hole in light-gauge metal
• Stainless steel head resists corrosion at the fastener face
• Steel body provides hardness and shear strength through the substrate
• 1/4-14 thread size for secure engagement in sheet metal applications
• Hex washer head with hex drive accepts standard 1/4 inch nut drivers and impact tools
• 100 screws per package suits production and service use

Compatibility

Designed as an OEM-style replacement or direct-use fastener for light-gauge metal-to-metal applications requiring a 1/4 inch hex washer head self-drilling screw with a Number 1 drill point.

Installation Notes

Self-drilling screws of this type are installed by HVAC technicians, sheet metal workers, and general contractors using a hex nut driver or impact driver set to a controlled clutch setting to avoid stripping. Ensure the substrate gauge is appropriate for a Number 1 drill point before installation. Do not over-drive — the hex washer head should seat flush without deforming the base material. Follow applicable codes such as SMACNA duct construction standards when using these fasteners in ductwork assemblies.
