High Precision Single Chamfered Hexagon Nut

High precision single chamfered hexagon nuts are forged from medium carbon steel, alloy steel, or boron steel. Through specific heat treatment processes such as quenching and tempering, these materials achieve the required hardness (approximately HRC 22-34) and tensile strength (at least 150 ksi / 1034 MPa at proof load).

This way, the nut can handle really strong clamping forces without stripping, bending, or breaking easily when under load.

Application

These high precision single chamfered hexagon nuts are required when joining large steel components.

They’re mainly used for bolting steel structures,like building frames (beams, columns), bridge girders, transmission towers, crane tracks, and the bases of heavy industrial equipment.

You have to use them for connections that need to be slip-critical or bearing-type. For these, how well the whole structure holds together depends on the fastener being able to stay tight and not give out.

Anti-corrosion measures in coastal environments

For high precision single chamfered hexagon nuts that are out in rough coastal or industrial areas, hot-dip galvanizing (HDG) that meets ASTM A153 is the go-to and most common way to keep them from rusting.

This tough zinc coating gives a strong, long-lasting protective layer and also provides cathodic protection. That stuff really matters for making the steel structure last and stay safe. And it works way better than regular zinc plating when things are rust-prone.
