Itw Buildex 560125 Self Drilling Screw 1/4-14 250 Pack

Product Description

The ITW BUILDEX 560125 is a self-drilling screw designed for fast, clean penetration into metal without a pre-drilled pilot hole. It features a 1/4-14 thread size with a No. 1 drill point that cuts its own path on contact. The hex washer head provides a broad bearing surface and is driven with a standard hex driver. At 7/8 inches in length under the head, this screw is well-suited for light-gauge metal-to-metal and metal-to-substrate fastening tasks common in HVAC, sheet metal, and general construction work. Each package contains 250 screws.

These screws are used across residential and light commercial applications wherever self-tapping fastening into thin-gauge steel is required. Common install scenarios include securing sheet metal ductwork, HVAC equipment panels, metal framing, and electrical enclosures. The hex washer head style is favored by sheet metal mechanics and HVAC installers for its ease of drive and resistance to cam-out during power tool use.

Key Features

• No. 1 drill point eliminates the need for a pilot hole in light-gauge steel
• 1/4-14 thread size provides strong thread engagement in thin metal
• Hex washer head delivers a wide bearing surface to prevent pull-through
• Hex drive compatible with standard 1/4-inch hex driver bits and nut setters
• Steel construction for strength in metal fastening applications
• 250-count package supports production-volume work

Compatibility

Designed as an OEM-style replacement and general-use self-drilling fastener for light-gauge metal-to-metal applications typical in HVAC, sheet metal fabrication, and metal framing installations.

Installation Notes

Self-drilling screws of this type are installed by sheet metal mechanics and HVAC technicians using a power drill or screw gun fitted with a 1/4-inch hex nut setter. Ensure the workpiece is secure before driving to prevent walking. Do not overdrive — the hex washer head should seat flush against the material surface without stripping. Follow applicable sheet metal and HVAC equipment manufacturer guidelines for fastener spacing and quantity.
