Product Description

Product Description

The Pre-Drill Jig, as shown in the video, is a helpful tool to support the 45° Wedge Washer installation in steel-to-wood connections with an accurate pilot hole. It offers several benefits, including a faster wood bite & installation, reduced risk of screw wandering, and help mitigating misalignment.


  • To be combined with MTC 45° Wedge Washer for a faster & more accurate installation process
  • Compatible with 3 fastener diameters, 5/16” [8 mm],3/8” [10mm],1/2″ [12 mm]
  • Cost efficient solution when multiple fasteners are to be installed


After drilling the pilot holes, it is important to clear any sawdust, or drill shavings created. It may seem trivial but sawdust may retain humidity which has the potential to damage steel connections over time.
