FAQs

Which grade chain is hardest to cut? ›

Industrial chain is rated by grades; the higher the grade number, the more steel alloying elements it contains and the more resistant it is to the variety of loads a chain encounters, especially in tension. Grades 70, 80, and 100 are among the hardest and toughest available.

The square link shape of the chain does not allow bolt cutters to get a proper grip and the lock has been specially designed to be nearly impossible to grip with burglary tools. You literally need an acetylene torch to defeat this chain, and even that will take a fair amount of time.

The Best Chain Has Hexagonal or Square Links

A heavy-duty, hardened steel chain with hexagonal links thwarts nearly every thief with a bolt cutter. Hexagonal links (or square or trapezoidal) make it impossible for bolt cutters to get a grip.

You should not use bolt cutters on hardened steel, or thick reinforced steel mesh. Hexagonal chains are difficult to get a suitable grip on with cutters.

Even if you have a very powerful bolt cutter, it is important to note that cutting a grade 80 steel security chain will be very difficult and time-consuming. It is also important to use caution when cutting any type of chain, as the jaws of the bolt cutter can shatter if they are overloaded.

Hardened Steel Bars: High-quality hardened steel bars are often used in security applications. They are extremely tough and difficult to cut with standard bolt cutters. Rebar or Reinforcing Steel: Reinforcing steel, also known as rebar, is very strong and can be used as cage material.
