A2-304 refers to 304-grade stainless steel, which is an austenitic alloy known for excellent corrosion resistance.
While A2 stainless steel is resistant to many conditions, 316-grade is typically recommended for direct marine/seawater exposure.
No, the setscrews are supplied individually; nuts should be purchased separately based on your specific requirements.
DIN 933 is a German industrial standard for hexagon head screws with full threading.
These are primarily designed for metal-to-metal applications, but they can be used in wood if paired with appropriate threaded inserts or washers.
Ensure the threads are clean and free of debris. Verify that the nut and bolt are both M10 sized.
Use a high-quality, properly sized wrench or socket that fits the hexagon head snugly to prevent slippage.
To install, ensure the hole is correctly aligned and the thread pitch matches your receiving nut or tapped hole. Use a calibrated spanner or socket wrench to tighten until the washer or head makes firm contact with the surface. Avoid over-tightening, which can strip threads. Because these are stainless steel, applying a small amount of anti-seize compound to the threads is recommended if you expect to remove the screw frequently in the future. Store in a dry place to prevent surface contamination.
