Itw Buildex 560064 Self Drilling Screw 1/4-20 3in 200pk

Product Description

The ITW BUILDEX 560064 is a 1/4-20 self drilling screw designed for fast, reliable fastening in steel and structural applications. With a flat head and Phillips drive, it sits flush with the work surface after installation. The number 4 drill point eliminates the need for a pre-drilled pilot hole, cutting through the base material as the screw is driven. At 3 inches overall length and a 1/4-20 thread pitch, this screw provides strong thread engagement in medium to heavy gauge steel. Each package contains 200 screws, suited for production work or high-volume job sites.

This screw is used in light structural steel framing, metal fabrication, HVAC ductwork support, and general sheet metal assembly. The flat head profile makes it a practical choice where a flush or countersunk finish is required on steel substrates. Trade professionals in mechanical, construction, and sheet metal work commonly specify this fastener for repetitive fastening tasks where drill-and-tap operations would slow production.

Key Features

• Number 4 drill point eliminates pre-drilling on compatible steel gauges
• 1/4-20 thread size provides strong pull-out resistance in steel
• Flat head seats flush for a clean, low-profile finish
• Phillips drive compatible with standard power tools and bit sets
• 3 inches overall length for medium-depth fastening applications
• 200-piece pack supports high-volume or production use

Compatibility

Designed as a standard 1/4-20 self drilling screw for use in steel fastening applications where a number 4 drill point and flat head profile are specified.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, and structural steel fabricators using a power drill or impact driver with a Phillips bit. Verify that the base material gauge is within the rated capacity of a number 4 drill point before driving. Apply consistent pressure to allow the drill point to engage cleanly before the threads advance. Follow applicable building codes and manufacturer torque guidance for structural connections.
