Expert Verdict — Reviewed by the SuperArbor Pro Desk
Structural screws like HeadLok speed up heavy wood-to-wood connections compared with through-bolting. Match screw length to total member thickness and follow FastenMaster's published fastening schedule for structural applications. Use a variable-speed drill and drive flush without over-torque.
Wear eye protection when driving structural screws and keep hands clear of the screw path.
