Malco HW10X11/2-50 Sheet Metal Screw 10x1.5in 50-pack

Product Description

The MALCO HW10X11/2-50 is a self-piercing sheet metal screw designed for fast, accurate fastening in light-gauge steel without requiring a pre-drilled pilot hole. Sized at #10 x 1.5 inches with a hex washer slotted head, this screw features a sharp tapered point type and a combination lead double thread that drives cleanly and seats flush. The zinc-plated, heat-treated steel construction resists corrosion and holds up under the mechanical stress common in duct fabrication and panel assembly. Sold in a pack of 50, it is a standard fastener for HVAC sheet metal work and general trade applications.

This screw is well suited for attaching sheet metal duct sections, flanges, and panels in residential and light commercial HVAC installations. The undercut-indented hex washer head provides a burr-free finish at the fastening surface, which matters in duct assemblies where sharp edges can compromise sealing or create airflow restrictions. HVAC sheet metal technicians and installers working with fabricated ductwork will find this a practical production fastener. The slotted drive allows use with standard hex-head drivers or slotted bits, giving the installer flexibility on the job site.

Key Features

• Self-piercing design drives through light-gauge sheet metal without pre-drilling
• Sharp tapered Type A point resists mushrooming, breaking, and walking on contact
• Combination lead double thread for positive engagement and fast seating
• Undercut-indented hex washer slotted head leaves a burr-free surface finish
• Zinc-plated and heat-treated steel for corrosion resistance and mechanical strength
• 50-count pack sized for production duct work and service van stocking

Compatibility

Designed as a standard #10 self-piercing sheet metal fastener suitable for light-gauge steel duct fabrication, panel attachment, and general sheet metal assembly in HVAC and related trade applications.

Installation Notes

Install with a hex-head nut driver or appropriate slotted bit set to controlled torque to avoid overdriving and stripping the hex washer head. Ensure sheet metal surfaces are clean and properly aligned before driving to take full advantage of the self-piercing point. Power down any associated air handling equipment before working on duct sections. Follow applicable SMACNA duct construction standards and local mechanical codes for fastener spacing and sealing requirements.
