Wood screw A4 | assortment box | 260 pieces

A smart solution for those who want to have the right wood screws close at hand – the assortment box contains wood screws in various dimensions, manufactured in stainless A4 / AISI 316 acid-proof steel. Perfect to keep in the tool cabinet, boat, car, or at the construction site – you avoid searching for loose screws and always have a durable and complete set on hand for fastening in demanding environments.

Thanks to the acid-proof steel, the screws can withstand moisture, salt, chemicals, and large temperature fluctuations – making them ideal for marine, outdoor, or industrial environments. When a certain dimension runs out in the box, you can easily top it up via our website.

FIELD OF APPLICATION

For fastening in wooden structures such as decks, panels, fences, marine installations, or other projects in exposed environments where durability and corrosion protection are crucial. The screws have Torx recesses for a secure grip and a countersunk head for a neat finish.

FREQUENTLY ASKED QUESTIONS (FAQ)

What are the benefits of an assortment box with A4 wood screws compared to buying loose bags of screws?

The assortment box gathers the most frequently used dimensions in a durable, well-organized case with clear compartments. This offers several practical advantages:

• Time saving: You don't have to measure and look for the right screw in the middle of a job.

• Flexibility: You have direct access to the right length and diameter for varied timber thicknesses in the boat, on the deck, or during assembly.

• Easy replenishment: The compartment layout makes it easy to see which dimensions are running low so you can restock with new A4 wood screws in bulk.

Why is acid-proof A4 / AISI 316 crucial for wood screws in outdoor and marine environments?

Wood absorbs and retains moisture for a long time. When moisture combines with tannic acid in wood species such as oak, larch, and hardwoods (or with saltwater and road salt), a highly corrosive environment is created. Acid-proof A4 steel (AISI 316 / 1.4401) contains molybdenum, which prevents rust, stress corrosion, and sheared screw heads. This ensures that the wooden structure stays together without unsightly rust stains.

Can you drive A4 wood screws directly into hardwood or is pre-drilling required?

For softer wood species like pine and spruce in standard dimensions, the screw works perfectly to drive in directly. When driving into hardwoods (such as oak, teak, cumaru) or when screwing close to end grain, pre-drilling and countersinking are always recommended. Because stainless and acid-proof steel are slightly softer than hardened carbon steel, pre-drilling reduces torque resistance and prevents the screw from binding or breaking.
