๐ Overview โ Extreme corrosion resistance for the toughest outdoor timber projects. When building decks, timber frames, or log cabins in harsh environments, you need fasteners that won't fail. Our #14 x 6" yellow coated structural lag screws have passed 1000 hours of salt spray testing โ no coating failure, no red rust. The T30 Star drive (Torx) eliminates cam-out and stripping, delivering consistent torque for a professional finish. A modified truss washer head distributes load and creates a flush, neat appearance without needing separate washers. The knurled shank reduces drilling torque and prevents wood splitting. Fully threaded for maximum grip. Perfect for outdoor construction, pole barns, decking, fencing, and log homes. 50 pieces plus one T30 star bit included โ ready for your toughest jobs.

๐ก Installation tip: Use the included T30 bit with an impact driver. For softwoods and pressure-treated lumber, no pre-drilling is needed. For dense hardwoods (oak, ipe), pre-drill a pilot hole about 75% of the screw diameter to prevent splitting. The knurled shank helps reduce driving torque.
๐ก๏ธ 1000-hour salt spray test passed โ This yellow coating meets industry standards for extreme corrosion resistance. Ideal for coastal decks, wet climates, and direct contact with pressure-treated lumber.
โ Frequently Asked Questions โ Yellow Coated Lag Screws
Do I need to pre-drill before using these 6" lag screws?
๐ง For most softwoods (pine, cedar, fir) and pressure-treated lumber, no pre-drilling is required โ the knurled shank and sharp point allow direct driving. For dense hardwoods (oak, hickory, ipe) or when screwing within 1" of the edge, we recommend pre-drilling a pilot hole about 75% of the screw diameter to prevent splitting and ensure easy driving.
Is the T30 star bit included? What size is it?
โ
Yes, the package includes one T30 star (Torx) bit that matches the screw head. The bit is compatible with standard impact drivers and drills, so you can start working immediately.
Will the yellow coating rust in coastal environments?
๐ No. These screws have passed 1000 hours of salt spray testing without coating failure. They are specifically designed for harsh outdoor conditions, including coastal decks and high-humidity areas. The yellow coating provides a robust anti-corrosion barrier that outperforms standard zinc or galvanized finishes.
What is the advantage of a modified truss washer head?
๐ The modified truss head combines a low-profile dome with an integrated washer. It distributes clamping load over a wider area than a standard hex head, eliminating the need for a separate flat washer. It also provides a flush, neat finish that looks professional on visible surfaces.
Can I use these screws for structural connections like ledger boards or beam ties?
๐๏ธ Yes. These #14 x 6" structural lag screws are suitable for many load-bearing applications, including ledger boards, beam-to-post connections, and timber framing. Always follow local building codes and use the correct number of fasteners per engineering specifications. The fully threaded design provides excellent pull-out resistance.
