When your outdoor project calls for shorter, heavy-duty fasteners that refuse to rust, these #14 x 3-inch structural lag screws step up. The 25āpack from Goobetter is purposeābuilt for deck boards, timber joints, and framing connections that don't require a full 4āinch length. Thanks to the yellow antiācorrosion coating that sailed through a 1000āhour salt spray test, you can drive these screws into treated lumber or exposed beams without worrying about rust streaks a season later. A T30 star drive eliminates stripped heads, while the knurled shank and truss washer head work together to reduce splitting and leave a flush, professional finish.

ā FAQ ā 3ā³ YellowāCoated Structural Lag Screws
š” How does the yellow coating compare to black oxide or galvanized?
The yellow coating on these lag screws is a thick, antiācorrosion layer that has independently passed a 1000āhour salt spray test. It provides excellent rust protection even in wet, outdoor environments, and the bright finish makes it easy to visually confirm coverage during installation.
š Are 3-inch lag screws long enough for deck ledger boards?
Typically, ledger boards require longer fasteners (4ā³ and up) to meet code. These 3āinch screws are ideal for decking boards, railings, timber connectors, and general framing. Always check your local building codes for specific structural requirements.
š§ Do I really get a star bit with the screws?
Yes. Every box of 25 lag screws includes one genuine T30 star bit. You can start your project right out of the box without hunting for a compatible driver.
š² Will these screw into hardwoods without splitting?
The knurled shank significantly reduces driving resistance and the risk of splits, but for very brittle or dense exotic hardwoods, we recommend preādrilling a 3/16ā³ pilot hole for best results.
š” Are the screws suitable for ināground or submerged applications?
These are built for outdoor aboveāground use. The yellow coating excels at resisting rain, humidity, and salt spray, but for constant underwater or burial environments, stainless steel fasteners are generally recommended.
š¦ Is it exactly 25 screws in the box?
Absolutely. Youāll receive 25 pieces of 3ā³ lag screws plus one T30 bit, all packed in a durable, reusable container that keeps your workshop tidy.
