Malco HW10X1Z-500 Sheet Metal Screw 10x1 Inch 500 Pack

Product Description

The MALCO HW10X1Z-500 is a self-piercing sheet metal screw designed for fast, clean fastening in light-gauge sheet metal applications. Sized at number 10 diameter by 1 inch in length, each screw features a burr-free hex washer slotted head with an undercut-indented design that delivers full operator control and precise hole alignment. The sharp tapered point is engineered to pierce sheet metal without mushrooming, breaking, or walking off center. Zinc plating and heat treatment provide corrosion resistance and the hardness needed to drive cleanly through metal without pre-drilling. Sold in a 500-count package, this is a volume fastener suited for repetitive sheet metal assembly work.

These screws are a standard choice for HVAC ductwork fabrication and installation, including connecting sheet metal duct sections, securing duct collars, and fastening register boots. The combination lead double-thread design speeds drive time and reduces cam-out during high-volume work. Sheet metal contractors, HVAC installers, and fabrication shops working with light-gauge steel will find this fastener appropriate for both field and shop use. The 500-count pack supports continuous production without frequent restocking.

Key Features

• Self-piercing sharp tapered point eliminates the need for pre-drilling in light-gauge sheet metal
• Burr-free hex washer slotted head reduces edge burring on finished sheet metal surfaces
• Undercut-indented hex washer head design provides precise alignment and full operator control
• Combination lead double thread for faster seating and reduced drive torque
• Heat-treated construction prevents point mushrooming or breakage during installation
• Zinc plated finish for corrosion resistance in typical HVAC and sheet metal environments

Compatibility

Designed as a standard replacement and volume-use fastener for light-gauge sheet metal assembly, including HVAC ductwork fabrication and related sheet metal construction applications.

Installation Notes

Sheet metal installers and HVAC mechanics typically install these screws using a hex-head screw gun or a slotted driver bit at controlled speed to prevent overdriving. Power down all associated HVAC equipment before fastening ductwork sections that are connected to live systems. Follow applicable mechanical codes, including SMACNA duct construction standards, for fastener spacing and gauge requirements. Avoid over-torquing, which can strip the hex washer head or deform light-gauge sheet metal.
