Multi-Mate screws are all-purpose, universal fasteners that provide strong holding power in a variety of different materials, including wood, metal, and masonry. A special point combined with a patented thread design provides an easy start, easy installation and eliminates pre-drilling in wood and thin-gauge (26-22 gauge) metal. The deep Phillips recess minimizes camout for trouble-free installation. An excellent fastening solution that can be used in a variety of applications.

  • All purpose, universal fastener for use in wood, metal and masonry
  • No pre-drilling in wood or light-gauge steel (26-22 gauge)
  • Ideal for multiple applications from general carpentry to construction
  • Zinc and wax coating reduces installation torque

Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Love them!!!! Used these to attach 2x2s to a block wall so I could use drywall. 5/32 bit is needed and is so small it drills easily compared to what tapcons use. They screw in very easy, just like using a phillips screw into wood (which you can use them for also.) They held great and not one stripped out. 55 of them was 7 bucks vs 70 tap cons at 28 bucks The only drawback is the longest I could find are 2 1/2. I wish they made 4 inch. April 8, 2011
