| Re: Warning Bolts!!
Scary stuff & just as well it happened when it did.
Just to clarify the bolt strength markings, the first number multiplied by 100 gives the nominal tensile strength in N/mm2, the second number divided by 10 gives the ratio between the nominal tensile and nominal yield strengths.
eg for a grade 8.8 bolt, the nom tensile strength is 800 N/mm2 and the nom yield strength is 0.8 times this figure = 640 N/mm2.
