Bobibbi Wood Screws #14

Technical details

For fastening timber in outdoor builds or landscaping, these Bobibbi heavy-duty wood screws are sized for substantial wood-to-wood work. Each screw is #14 in diameter (6.35 mm) and 3 inches (75 mm) long, with a washer head and a black Ruspert coating. The pack contains 50 screws. Their T30 star drive and serrated threads are intended to make installation steadier and help the screw hold securely.

The screws are made from carbon steel. The product description claims more than 1,500 hours of corrosion resistance for the coating, but that figure is not a substitute for checking whether a particular project needs a specific outdoor or structural rating. No load capacity is provided, so don’t use the listed dimensions alone to decide whether a connection is suitable for a safety-critical build.

Getting the most from it

These are presented for hardwood, softwood, fiberboard, particle board, thin metal sheets, structural timber, logs, landscaping, decking, and outdoor construction. That breadth makes them worth considering for general project work where a thicker, longer screw is useful. They’re a different approach from small general-purpose wood screws: the #14 diameter and 3-inch length are aimed at more substantial fastening, not delicate trim or small parts.

A Type 17 point is designed to reduce splitting as the screw enters wood, while the serrated threads are meant to improve grip. Those features can help, but wood species, board thickness, and placement still matter. The listing doesn’t provide a load rating or a specific structural code approval, so don’t assume the screws replace hardware selected to a project’s engineering requirements.

Usage tips

Use a T30 star-drive bit, as specified, and keep the driver aligned with the screw head while fastening. For example, when attaching a timber member in a landscaping project, position the pieces first, then drive the screw straight so the washer head seats against the wood. The star drive is intended to transmit torque with less chance of stripping than a less secure drive style, but forcing a misaligned bit can still damage the head.

A Type 17 point is meant to help limit splitting, it doesn’t guarantee that every board can be driven without preparation. If the wood is narrow, brittle, or close to an edge, think through placement before driving. A solid pick if your project calls for long, #14 screws and a T30 bit. It might not be a great match if you need verified load data, a different drive style, or fasteners for fine woodworking.

Questions before you buy

What bit do these screws use? The listed drive is T30 star (Torx), so you’ll need a matching bit.

What does the Type 17 point do? It is designed to help prevent wood from splitting during installation, results can still depend on the wood and where the screw goes.

Are they intended for outdoor projects? The listing includes decking, landscaping, and outdoor construction, and claims more than 1,500 hours of corrosion resistance for the Black Ruspert coating. It does not specify a project-specific exposure rating.

Is it worth it?

These screws make sense when you want a 3-inch, #14 fastener for timber, logs, or outdoor construction and can use a T30 driver. The washer head, serrated threads, and Type 17 point give a practical reason to choose them over a smaller, more basic wood screw for heavier fastening tasks. The key limitation is missing load-capacity information: for a connection where structural performance must be verified, select fasteners against the project requirements rather than relying on size or coating claims alone. For ordinary project work that fits the listed materials and dimensions, the 50-pack offers a straightforward supply, for delicate jobs or engineered connections, a more specifically documented fastener is the safer choice.
