Screws and nuts

Ensure solid, watertight deck solutions

Screws and nuts include classic deck fittings and fasteners that are often overlooked in everyday life – until they are missing.

Here, precise dimensions, material, and clean installation are key. Stainless steel is durable and corrosion-resistant, while brass and bronze are traditional and robust.

With the right selection, everything fits securely, cleanly, and remains watertight long-term.

Discover variants, materials, and designs built for marine use. This way, you'll find equipment that remains reliable on board – season after season.

Deine Fragen / Unsere Antworte

What is the difference between A2 and A4 stainless steel screws, and which ones do I need on deck?
A4 stainless steel contains molybdenum and is significantly more resistant to saltwater and chlorides than A2. Therefore, for all applications on deck or at the waterline, we exclusively recommend A4. A2 is sufficient for protected indoor areas.
How do I know if my boat has metric or imperial threads?
The safest way is with a thread gauge, which you can get at a specialist store. Alternatively, you can bring the removed screw to us or measure the pitch with calipers and compare it with a thread chart. Boats of British or American origin often have BSW or UNC threads.
Do I need to be careful when screwing into a GRP deck?
Yes: Always pre-drill a suitable pilot hole to avoid cracks in the laminate. Apply sealant under the fitting and only tighten the screw hand-tight – too much torque will squeeze out the sealant and can damage the laminate.
Can stainless steel screws corrode in aluminum fittings?
Yes, due to galvanic corrosion between the dissimilar metals, the screw can seize up and the aluminum fitting can locally dissolve. A thin application of insulating paste or assembly grease on the thread when screwing it in reliably prevents this.
