In this review of the Jake Sales #14 x 2-1/2 in heavy duty black timber screws, the bottom line is simple: these screws are aimed at landscapers, timberframers and DIYers who need reliable holding power for exterior timber projects.

• Corrosion resistant coating: The black exterior coating passed 1000 hour salt spray testing, delivering long-term protection for outdoor use and ACQ treated lumber.
• Deep sharp threads: Wide, aggressive threads give maximum holding power while requiring less torque to drive, reducing effort and split risk.
• Knurled shoulder: Drag reducing knurled shoulders make installation smoother and help the screw pull timber tightly together without excessive binding.
• Box quantity: A full box of 1,000 screws supplies large jobs conveniently and reduces trips to source more fasteners mid-project.

Who It's For

These screws are ideal for landscapers, deck builders, and homeowners working with log, timber and landscaping timbers who need heavy duty fasteners compatible with ACQ treated lumber.
