Top Side Drill Screws for Mezzanine Flooring

ResinDek® top side drill screws are engineered for strength, durability and easy installation.

The number 2 square drive heads and points easily pierce up to 12 gauge steel decking and is designed to drill through wood and steel decking prior to the threads engaging, thus preventing the panels from lifting.

  • Available in collated strips

Invis-Loc Fastening System
Invisi-Loc® Underside Fastening Systems for Mezzanine Decking

Invisi-Loc® provides showcase mezzanine floors with no visible fasteners that are dependable, economical and easy to install. The Invisi-Loc® fastening system mounts fasteners under the mezzanine decking hiding unwanted screw holes on top. Plus, when installed with our pre-punched corrugated metal decking, installation time is reduced and potentially dangerous metal shavings are eliminated.

  • 20 Invisi-Loc® fasteners are required per 4' x 8' sheet. A pneudraulic installation tool and a standard medium duty air compressor supplies the required power.
  • Corrugated metal decking is pre-punched and B metal deck is fastened to the bar joists like other steel decking using drilling screws or welding.
  • All pneudraulic installation tools can be rented or purchased from Cornerstone Specialty Wood Products, LLC.
  • When installed according to Cornerstone Specialty Wood Products specifications the Invisi-Loc® Underside Fastening System carries a 10-year warranty.
Collated Screws for Corrugated Metal Deck

B-Deck screws work best in roll form beams and structural steel under 3/16" thick. Valleys less than 2- 1/2" wide may not accommodate the screw gun. Contact Cornerstone Specialty Wood Products for additional information.
