came across some grade 8 steel bolts and got curious what exactly makes them different from lower grades is it just the material or is there more to it also if you use a grade 8 bolt do you have to pair it with grade 8 nuts and washers or does it not matter
trying to make a diy lawn roller like the ones they use to smooth tennis courts wanna use recycled stuff maybe junkyard parts any ideas or suggestions? not trying to spend much just want something that gets the job done thx in advance
