How many screws come in a single order?

These screws are sold individually as single pieces. This allows you to purchase the exact quantity you need for your project without buying excess inventory. If you need multiple screws, please adjust the quantity in your cart before checking out.

Can I use these stainless steel screws for outdoor or wet environments?

Yes, these screws are made from AISI 304 austenitic stainless steel. This material provides excellent corrosion resistance against rain, humidity, and mild outdoor elements. However, for direct saltwater submersion, we recommend upgrading to 316-grade stainless steel instead.

What kind of hole and tool do I need to install these DIN7991 screws?

You will need a matching Allen key to drive the hex socket. Since these are flat head screws, you must pre-drill and countersink the hole to a 90-degree angle. This preparation ensures the screw head sits perfectly flush with your material's surface.
