What Customers Are Saying
Customers overwhelmingly praise these screws for exceptional driving performance, consistently noting they penetrate warped and treated lumber effortlessly without pre-drilling, with the T25 star bit preventing stripping and maintaining perfect torque control. Reviewers highlight superior strength and holding power in heavy-duty applications like securing posts and railings, comparing them favorably to traditional lag bolts. Most express deep loyalty, stating they will repurchase and calling them the best available. A few mention high pricing and occasional stripping on pallet wood, but these concerns are vastly outweighed by widespread satisfaction and reliability.
