Can someone tell me the shear strength of a 1/2" bolt in grade 2 and grade 5.
Reason I ask.
I bought a Howse 5 foot economy brush cutter. Has been working great so far.
It has a cutting capacity of 1.5 inches
I am under the impression that grade 2 bolts should be used for shear bolts but the manufacture web site says to use 1/2" X 3 1/2" BOLT NC GR5 HHCS ZINC for the shear bolt.
The dealer gave me several bolts when I bought the cutter but I do not know what grade they are.
They only have the letters SBY on the head of the bolt.
Thanks for your help.
