NateDJ Posted October 3, 2008 Share Posted October 3, 2008 Will grade 8 bolts make decent punches or drifts? I can not find any information as to the carbon content or the steel type of these things but I am hoping to at least make a drift and a small shaping hammer from them. Any Ideas?

rlarkin Posted October 3, 2008 Share Posted October 3, 2008 Grade 8 refers to the highest standard strength achieved in the manufacture of bolts and hex cap screws. Grade 8 bolts are medium carbon alloy steel, quenched and tempered at a minimum temperature of 800 Quote Link to comment Share on other sites More sharing options...
orgtwister Posted October 4, 2008 Share Posted October 4, 2008 well i don't know persay if they would make a good punch or any thing else i can tell you you can't weld them if you do i makes them week and they break off i worked at a place were they insisted on welding them against my concern on a pieace of equitment and like i told them they all broke off so then we just ground down the welds and bolted it back to getther and it worked fine Quote Link to comment Share on other sites More sharing options...
orgtwister Posted October 4, 2008 Share Posted October 4, 2008 for punches i would just order some h-13 from speedy metals a 12 inch pieace of 1/2 is like 4.50 i think that would be the best thing to use Quote Link to comment Share on other sites More sharing options...
metalmangeler Posted October 4, 2008 Share Posted October 4, 2008 If the punches and drifts get hot they would be better made from h-13 as stated, I would think that if you can heat treat it close to right then it should work fine for a shaping hammer as would truck Axel or heavy coil spring.
