Malco HW10X1/2Z-1M Sheet Metal Screw 10x1/2 Hex 1000pk

Product Description

The MALCO HW10X1/2Z-1M is a self-piercing sheet metal screw engineered for fast, reliable fastening in light-gauge metal applications. Sized at number 10 by 0.5 inches with a 0.25-inch hex washer head, this screw features a combination lead double thread and a sharp tapered point designed to pierce sheet metal cleanly without pre-drilling. The zinc plated, heat treated construction resists corrosion and provides the shear strength needed in demanding field conditions. HVAC installers, sheet metal workers, and mechanical contractors rely on this screw for ductwork assembly and metal panel attachment. Each pack contains 1,000 screws.

This fastener is suited for residential and light commercial HVAC ductwork, metal framing, and sheet metal enclosure work. The burr-free hex washer slotted head allows use with both hex drivers and flathead bits, giving installers flexibility on the job. The undercut-indented head design seats flush and reduces the risk of tearing thin gauge metal. The sharp tapered point self-aligns on contact, giving the installer precise hole placement without the screw walking or mushrooming under pressure.

Key Features

• Self-piercing sharp tapered point eliminates pre-drilling on light-gauge sheet metal
• Combination lead double thread for fast drive speed and firm seating
• Burr-free hex washer slotted head accepts hex or flathead drive
• Undercut-indented head reduces metal tearing and seats flush
• Zinc plated finish for corrosion resistance
• Heat treated for consistent strength and hardness
• 1,000 screws per pack for high-volume production work

Compatibility

Designed for use with light-gauge sheet metal in standard HVAC ductwork fabrication and installation applications.

Installation Notes

Sheet metal screws of this type are typically installed by HVAC technicians and sheet metal mechanics using a hex-head driver or combination screwdriver bit. Ensure the sheet metal surfaces are aligned and clamped before driving to take full advantage of the self-piercing point. Avoid over-torquing, which can strip the head or deform thin gauge material. Follow applicable mechanical and HVAC codes for fastener spacing on ductwork joints and seams.
