Malco HW10X2-50 Self-piercing Sheet Metal Screw 50 Pack

Product Description

The MALCO HW10X2-50 is a self-piercing sheet metal screw designed for fast, clean fastening in sheet metal applications without the need for pre-drilling. Sized at 10 x 2 inches with a hex washer slotted head, this screw features a sharp tapered Type A point that aligns precisely and will not mushroom, break, or walk during installation. The steel construction is zinc plated and heat treated for corrosion resistance and consistent performance. Sold in a pack of 50, these screws are a standard consumable for HVAC duct fabrication and sheet metal assembly work.

These screws are well suited for residential and light commercial HVAC ductwork installation, sheet metal fabrication shops, and general trade use wherever galvanized or light-gauge steel panels are joined. The combination lead double thread design and sharp tapered point allow the fastener to pierce and thread simultaneously, reducing installation time. The 5/16-inch hex washer head provides a burr-free contact surface and accepts a standard hex driver or slotted bit, giving the installer complete control over seating depth and hole alignment.

Key Features

• Self-piercing Type A point eliminates pre-drilling in light-gauge sheet metal
• Sharp tapered point resists mushrooming, breaking, and walking during drive
• Combination lead double thread for faster engagement and secure hold
• Undercut-indented hex washer slotted head delivers burr-free seating
• Zinc plated, heat treated steel construction for durability and corrosion resistance
• 50-count pack sized for jobsite and truck stock replenishment

Compatibility

Designed as an OEM-style fastener for light-gauge sheet metal ductwork, panels, and enclosures in HVAC fabrication and installation applications.

Installation Notes

Installation is typically performed by sheet metal workers or HVAC technicians using a hex driver or slotted bit matched to the head style. No pre-drilling is required in light-gauge material, but pilot holes may be needed in heavier gauges. Verify fastener length is appropriate for the combined material stack before driving. Follow applicable mechanical codes and manufacturer guidelines for screw spacing in duct assembly.
