Hardwood Wrench™ Deck Board Straightener

The Hardwood Wrench™ is the original patented deck board straightening tool that revolutionized hardwood deck installation. With up to 1,100 pounds of pushing force, this professional-grade tool bends even the most warped exotic hardwood boards straight while you install fasteners—hands-free. The self-locking cam mechanism holds boards in position, enabling true "one-man, one-hand installation." High-quality anodized aircraft-grade aluminum body with solid American Ash wood handle. Works with single or double joists up to 3.5" wide and all decking types: pre-grooved, standard lumber, composites, and PVC. Adjustable knurled stainless steel joist pins grip securely. Reversible handle accommodates left or right-handed use. Eliminates the back-breaking chisel-and-pry method that's been passed down for generations. U.S. patented design.

Essential Tools for Hardwood Deck Installation

1

Board Straightener

Dense hardwood boards often arrive with slight bow or twist. A lever-style straightener lets one person pull boards straight while fastening — saving time and preventing waste.

2

Countersink/Pre-Drill Combo

A Drill & Drive® tool cuts the pilot hole and countersink in one pass. This single step replaces two separate operations and keeps spacing consistent across hundreds of holes.

3

Slotting Router Bit

If you need to groove boards on-site for hidden clips, a carbide-tipped 1/8″ × 3/8″ router bit handles even the hardest Ipe. Run at moderate speed to avoid burning the wood.

4

Gap Spacers

Precision plastic spacers maintain uniform board-to-board gaps without eyeballing. They remove any guesswork and keep your lines straight from edge to edge.

Pro Tip from Our Deck Specialists

Carbide-tipped bits last 5-10× longer than HSS in tropical hardwoods. The initial cost is higher, but you will burn through standard bits in less than a day on an Ipe deck.
