Vis de diamètre #16

Welcome to the “16-Diameter Screws” collection at Old West Iron. This set is organized by shank (gauge) diameter — specifically screws with a #16 gauge — and not by head size or style. A #16 screw has a shank (major-thread) diameter of approximately 0.268 inches (≈ 17/64 in) according to standard wood-screw size charts. 

These #16 screws fall into the heavy-duty range. Their larger diameter delivers significantly stronger holding power and greater load-bearing capacity than smaller gauges — making them suited for demanding projects: structural woodwork, heavy framing, thick lumber, large timbers, heavy cabinetry or furniture, and other jobs where maximum strength and durability matter.

FAQ

Q: What does “#16” mean on a screw?
A: “#16” refers to the screw’s gauge — the nominal size of the diameter of its shank (the threaded shaft), not the size or shape of the head. 

Q: Why are the screws grouped by shank diameter instead of head size?
A: Because the shank diameter determines the screw’s holding strength, load capacity, and the size of pilot holes needed. Head size or style affects only how the screw sits or looks in the material — not its structural capacity. 

Q: What kind of projects should I use a #16 screw for?
A: Use #16 screws when you need heavy-duty fastening — thick lumber, structural assemblies, heavy framing, or any joinery where strength and reliability are critical. Their larger diameter resists shear and pull-out better than lighter gauge screws.

Q: Will screws under the #16 grouping have different head styles?
A: Yes. Because we group by shank diameter only, screws may have various head styles (flat-head, round-head, decorative head, etc.). The head style affects appearance or how the screw sits, but not its gauge or structural capacity.

Q: Do I need to pre-drill pilot holes for #16 screws?
A: In most wood applications, yes — especially with dense or hard woods. Pre-drilling a pilot hole sized roughly to the screw’s root or minor-thread diameter helps prevent splitting and ensures a stronger, cleaner hold.
