Itw Buildex 560128 Self Drilling Screw 1/4 in 100 Pack

Product Description

The ITW BUILDEX 560128 is a 1/4 inch 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 No. 3 drill point, which eliminates the need for a pilot hole and speeds up installation. The screw measures 1 inch in length under the head and is manufactured from steel for strength and durability. It is sold in a package of 100 units. HVAC technicians, sheet metal workers, and mechanical contractors regularly use this fastener type when assembling ductwork, equipment panels, and light structural steel components.

This fastener is suited for light-gauge steel applications commonly found in commercial and residential HVAC installations, electrical enclosures, and mechanical equipment assembly. The 1/4-14 thread size and No. 3 drill point make it appropriate for use in sheet metal connections where a self-tapping action is required without pre-drilling. It is packaged in a quantity of 100, which suits both service-call use and larger installation projects.

Key Features

• No. 3 drill point drills and taps in a single pass, eliminating pilot hole preparation
• 1/4-14 thread size provides strong thread engagement in light-gauge steel
• Hex washer head distributes clamping load and resists pull-through
• Hex drive compatible with standard 1/4 inch hex bit drivers and nut drivers
• Steel construction for structural integrity in mechanical and sheet metal applications
• Packaged in 100-count units for efficient jobsite or service-van stocking

Compatibility

Designed as a standard 1/4 inch self-drilling screw for use in light-gauge steel fastening applications typical of HVAC ductwork, equipment panels, and mechanical enclosures.

Installation Notes

Installation is performed with a hex driver or nut driver fitted with a 1/4 inch hex bit. Ensure the substrate material and gauge are within the rated capacity of a No. 3 drill point before driving. Do not overdrive — stop when the washer head seats flush to avoid stripping the threads or deforming the substrate. Follow applicable mechanical codes and manufacturer guidelines for fastener spacing and load requirements.
