DOE Suspect or Counterfeit Bolts
DOE Suspect or Counterfeit Bolt Headmark List:
The Grade in the US or Class (Import) refers to the mechanical properties of the material used to manufacture the bolt and nut. Generally, a higher number indicates a stronger, hardened fastener (and generally a higher number can be more brittle). Manufacturers of load control products must keep in mind foreseeable stresses products may encounter and optimize the bolt for material choice, diameter and sheer strength. For most products, RatchetStrap.com specifies medium carbon steel alloy bolts and nuts (Grade 8). While this adds to our products' ultimate cost, it provides the most favorable result of high strength performance for expected and foreseeable use.
It is very important to note that when formed by a process called Upset Forging, the Head of the Bolt must also have the Bolt Manufacturer's name, logo or marking in addition to the markings pictured above.
