Frequently Asked Questions

What is a MALCO self-piercing screw used for?

A MALCO self-piercing screw is used to fasten sheet metal without pre-drilling, making it ideal for HVAC ductwork, metal roofing, and general fabrication. The #8 size, 1 1/2 in length, and hex washer head provide secure, flush fastening in steel and aluminum assemblies.

What are the specifications of the MALCO HW8X1-1/2ZT screw?

The MALCO HW8X1-1/2ZT is a #8 size, 1 1/2 in long, steel, zinc-plated, slotted hex washer sheet metal screw. It has a 1/4 in drive size and comes in a 250-piece pack. The zinc plating offers corrosion resistance for indoor and outdoor applications.

Where to buy MALCO self-piercing screws worldwide?

How to install a self-piercing screw in sheet metal?

Use a power driver with a 1/4 in hex bit. Align the screw perpendicular to the metal surface and drive it straight in. The self-piercing tip cuts its own hole, so no pre-drilling is needed. Avoid over-torquing to prevent stripping the zinc-plated steel head.
