NBN – National Bolt & Nut, USA.

These came to us as part of an Andrew VHLP1/VHLP2 Antenna mounting kit. They are a little unusual in that they come in a sealed bag which also includes what looks like grey silicon sealer, they also have what looks like a flat headed pin at the bottom of the threaded section.

The “70” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture). Therefore, A4-70 is an austenitic, acid proof stainless grade (usually 316 material – 316 or 316L) which has been cold worked to provide a minimum tensile strength of 700N/mm² (MPa).A4 stainless steel contains carbon, silicon, manganese, phosphorous, sulphur, chromium, molybdenum, and nickel. These elements make fixings manufactured from A4 steel very resistant to corrosion and less reactive to other materials.

A4 stainless steel fasteners are typically known as marine grade stainless fasteners due to their resistance to salt water corrosion and can be found in a number of water-based applications. It is also resistant to salt spray.
