FAQPage

What are lag screws and carriage bolts used for?

Lag screws are heavy-duty fasteners ideal for timber framing, beams, gates, pergolas, and structural wood connections. Carriage bolts are used for through-bolting applications in furniture, barns, timber structures, and restoration projects where a domed, finished head is preferred.

How are your lag screws and bolts different from standard hardware-store fasteners?

Old West Iron fasteners are made from higher-grade steel with deeper threads, stronger shanks, and optional hand-finished or historic styling. They outperform mass-produced imports and visually complement rustic, heritage, and handcrafted hardware.

How do I choose the right size bolt or lag screw?

Match the fastener diameter to your load requirements. Lag screws should penetrate at least half the thickness of the timber. Carriage bolts should be long enough to pass fully through the material and allow space for washers and a nut.

Are your lag screws and bolts hand-forged?

The threaded shafts are precision-machined for consistency, while many decorative heads—hammered, flower, rustic dome—are hand-finished or textured by our American blacksmiths for true old-world character.

What are the lead times on lags and bolts and where are they made?

Most orders ship within 1–10 business days, depending on quantity and finish. All decorative and custom-finished lag screws, bolts, and carriage bolts are made or finished in the USA at our Idaho forge.
