Hillman 561042 Washer Head Self-drilling Screw 100 Ct

Product Description

The HILLMAN 561042 is a washer head self-drilling sheet metal screw designed for roofing construction and general fastening applications in wood, fiberglass, and thin-gauge steel. The drill point eliminates the need for pre-drilled holes, allowing the screw to penetrate and tap its own mating thread in a single operation. A factory-installed neoprene washer under the head creates a water-tight seal at the fastener point and acts as a corrosion buffer between dissimilar surfaces. Each screw measures 12-14 by 1.5 inches and the package contains 100 pieces. Zinc construction provides baseline corrosion resistance. These are a standard choice for licensed roofers, sheet metal mechanics, and general contractors working with metal panel systems.

This screw is suited for residential and light commercial roofing panels, metal-to-wood substrate connections, fiberglass panel attachment, and thin-gauge sheet metal assembly. The self-drilling tip reduces installation time on production roofing work where pre-drilling would add significant labor. The neoprene washer seal makes it particularly appropriate for exposed fastener metal roof systems where weather infiltration at the fastener is a primary concern.

Key Features

• Self-drilling tip penetrates thin-gauge steel without pre-drilling
• Sharp threads form their own mating thread for a secure mechanical grip
• Neoprene washer under the head provides a water-tight seal
• Neoprene barrier reduces galvanic corrosion between contact surfaces
• Zinc construction for baseline corrosion resistance
• 100 screws per box for production-quantity roofing work

Compatibility

Designed for use in wood, fiberglass, and thin-gauge sheet metal substrates; well-suited as a standard exposed-fastener roofing screw for metal panel roof systems.

Installation Notes

Installation is typically performed by licensed roofers or sheet metal mechanics using a variable-speed drill driver with a hex-head bit. Apply consistent, controlled drive pressure to avoid overdriving and compressing the neoprene washer beyond its effective sealing range. Disconnect or lock out any powered equipment in the work area before working near live electrical components on a rooftop. Follow applicable local building codes and manufacturer panel specifications for fastener spacing and edge distance.
