Itw Buildex 560057 Self Drilling Screw 1/4-14 250 Pack

Product Description

The ITW BUILDEX 560057 is a 1/4-14 self drilling screw designed for fast, reliable fastening in steel-to-steel and steel-to-substrate applications. It features a hex washer head with a hex drive and a number 3 drill point that cuts its own hole without pre-drilling. The 1.5-inch length under head provides adequate thread engagement across a range of material thicknesses. This screw is manufactured from steel and sold in a package of 250. It is a standard fastener used by HVAC installers, sheet metal workers, electricians, and general construction trades.

This screw is suited for light-gauge steel framing, HVAC ductwork, metal roofing panels, and similar sheet metal assemblies. The 1/4-14 thread pitch and number 3 drill point make it appropriate for drilling into steel in the light to medium gauge range. It is commonly used in both residential and commercial construction settings where speed and consistent pull-through strength matter. The package quantity of 250 units supports production-level installation work.

Key Features

• Number 3 drill point self-taps through steel without pre-drilling
• 1/4-14 thread size provides strong thread engagement in sheet metal
• Hex washer head distributes clamping load and resists pull-through
• Hex drive compatible with standard 1/4-inch hex driver bits and impact drivers
• Steel construction for durability in structural and mechanical fastening
• 250-count package suited for high-volume trade work

Compatibility

Designed as an OEM-style replacement and standard-fit fastener for light-gauge steel applications including HVAC ductwork, metal framing, and sheet metal panel assemblies requiring a 1/4-14 self drilling screw with a hex washer head.

Installation Notes

Installation is performed by HVAC technicians, sheet metal workers, and general construction tradespeople using a 1/4-inch hex driver or impact driver. Confirm that the base material gauge falls within the rated capacity of a number 3 drill point before driving. Do not overdrive the screw, as stripping the threads or deforming the washer head will reduce clamping force. Follow applicable building and mechanical codes for fastener spacing and edge distance in structural applications.
