SS Coachscrews at Bunnings - Are they ok?	31-Jul-2014 At 9:27:35 AM	mikllaw

If it's a bolt, Bubba can shear it, the A2 maximum torque on a 10 mm shaft is only 44 Nm, about 20 kg force on a 150 mm shifter. Cheap nasty stainless ones will shear easier. if they are glued in, no torque is involved and so long as they have at least 30 mm unthreaded shoulder they will be fine. But if you're using them as a (ground-up) soft rock screw-in anchor, it is possible to damage them by over-torquing. I'd use screwbolts as they are much stronger (ave strength outwards 27 kN) than stainless coachbolts ((ave strength outwards 18 kN) , then unscrew them and glue in a machine bolt or ring
