Hardwood Wrench Jr.™ Deck Board Straightener
The Hardwood Wrench Jr.™ is a scaled-down, lighter version of the professional Hardwood Wrench™ designed for DIY homeowners and weekend deck builders.

Straightens hardwoods, thermally modified woods, pressure-treated lumber, and composites with ease. Works on single or double joists up to 3.5" wide. The multi-directional handle operates left or right-handed. Self-locking cam holds boards straight while you install fasteners—no helper needed. Perfect for smaller projects or as a backup tool on professional jobsites. U.S. patented design.

Why Choose Tools & Drill Bits?
Essential Tools for Hardwood Deck Installation
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.
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.
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.
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.
