The Unifix A2-304 Stainless Steel Hexagon Bolts are high-strength industrial fasteners designed for professionals and DIY enthusiasts requiring reliable structural integrity in corrosive environments. These M16 x 100 bolts offer excellent resistance to oxidation due to their A2-304 grade construction, making them ideal for outdoor and marine-adjacent projects; however, users should be aware that they are not suitable for high-acid environments where specialized alloys are required.

A2-304 is a standard grade of stainless steel that contains chromium and nickel, providing excellent resistance to corrosion and oxidation in general outdoor settings.
While highly resistant to corrosion, A2-304 is generally recommended for general outdoor use. For direct contact with saltwater, A4 grade stainless steel is typically preferred.
DIN 931 is a German industrial standard for hexagon head bolts that are partially threaded.
Yes, it is recommended to use stainless steel nuts (preferably A2 grade) to ensure compatibility and prevent galvanic corrosion.
A2-304 stainless steel is generally considered non-magnetic in its annealed state, though slight magnetism can occur due to the cold-working process used in bolt manufacturing.
Check for debris in the threads and apply a thin layer of anti-seize compound to reduce friction.
Ensure the wrench or socket is the correct metric size and sits flush against the hexagon flats.
Clean the area with a mild stainless steel cleaner and ensure no iron-based tools have left metal filings on the surface.
To install these bolts, ensure you have a properly sized socket or spanner to fit the hexagon head. When tightening, apply torque evenly to prevent stripping. It is recommended to use an anti-seize lubricant on the threads prior to installation, as stainless steel is prone to seizing or 'galling' during high-friction fastening. When storing these bolts, keep them in a dry area away from carbon steel dust or tools, as iron particles can settle on the surface and initiate surface rust on otherwise durable stainless steel.
