Tornillos de diámetro n.° 24

Welcome to the “24-Diameter Screws” collection at Old West Iron. This section organizes our screws by shank (major-thread) diameter — in this case, screws sized “#24” — rather than by head size or style. According to standard screw-size charts, a #24 screw corresponds to a major-thread (outer) diameter of about 0.372 inches (≈ 3/8″). 

These #24 screws are among the largest standard-gauge wood screws — built for heavy-duty, load-bearing tasks where maximum strength and durability are required. Think large structural woodwork, thick timber framing, heavy-duty exterior builds, barns, heavy furniture or cabinetry, decks, and any project where you need substantial holding power and long-term reliability.

FAQ

Q: What does “#24” mean on these screws?
A: “#24” is the screw gauge — it refers to the diameter of the screw’s threads (the major or outside-thread diameter), not the size or shape of the head. 

Q: Why are the screws grouped by shank/ thread diameter instead of head size?
A: Because structural strength, holding capacity, how much load a screw can bear, and what size pilot-holes or clearance holes are needed are determined by the shank (thread) diameter. Head style or size affects only appearance or how the screw sits — not its gauge or structural capacity. 

Q: What kinds of projects are #24 screws suited for?
A: #24 screws are ideal for heavy-duty structural or load-bearing tasks — thick lumber framing, large timber construction, heavy exterior structures, decks, barns, heavy furniture, or other projects requiring maximum holding strength and durability.

Q: Will screws in the #24 collection have different head types or lengths?
A: Yes. Because our grouping is by diameter only, screws under #24 may come with a variety of head styles (flat-head, round-head, decorative, etc.) and different lengths depending on the use. Head style and length affect installation and appearance, but not the gauge or structural capacity.

Q: Should I pre-drill before using a #24 screw?
A: Yes — especially if you’re working with dense or thick lumber. Drilling a pilot hole appropriately sized (just under the screw’s root/ minor-thread diameter) helps prevent splitting and ensures the threads bite cleanly and hold securely under load.
