Appendix of Interesting (or at least useful) Information:

Bolt Specifications:

These are placed in ascending order of strength
All markings will be made on the top of the bolt & sometimes on the nut too.
Never ever use plain bolts for anything other than garden furniture.


Imperial Bolts:

       A
       R
       S Minimum standard for general fixings
       X

Metric Bolts:
      8.8 Minimum standard for general fixings
     10.9
     12.9

Metal Myths:

bulletTitanium is NOT any stronger than alloy steel, it is just half the weight.
bulletEven Aerospace grade aluminium alloys are no stronger than good steel, they're much more brittle too and are not weldable (unless you have a laser welding robot in your garage).
bulletStainless steel is not 100% immune from corrosion its just much more resistant than normal steels.
bulletALL steels no matter how exotic exhibit the SAME stiffness values. Only the strength changes.
bulletStainless, Molybdenum, Nickel alloy steel, etc.: all the same stiffness.

Strange But True Pointless Facts:

bulletA bolt made of Beryllium will FLOAT in salt water!
bulletSpruce wood exhibits a superior strength to weight ratio than alloy steel!
