dean_redzic Posted July 1 Share Posted July 1 Hello, Are the horrido bolts (4.8, A2, A4 etc) harder to bend than drill rod or even grade 5 bolts at the same krahling rating? I know ratings are only approximate but I have bent a grade 5 at approximately 420lbs, but a 220lb 4.8 is much harder. Is it possible that the bolts vary that much? I have matched the markings to the eat chalk get big ratings Quote Link to comment Share on other sites More sharing options...
sid_arnes Posted July 2 Share Posted July 2 Is the grade 5 a 1/4×6"? If so then the increased difficulty could be the length. 420@7" is not the same bend as 420@6". Quote Link to comment Share on other sites More sharing options...
dean_redzic Posted July 2 Author Share Posted July 2 Yeah it is 6" (silver NY grade 5 1/4"x6") The 4.8 is 7" but only 220lbs according to the chart Quote Link to comment Share on other sites More sharing options...
sid_arnes Posted July 2 Share Posted July 2 That g5 is definetly the harder bend. If you are new to 7" stock then you just have to adapt to length. It is a big inch. 1 Quote Link to comment Share on other sites More sharing options...
Fist of Fury Posted July 2 Share Posted July 2 I know grade 5 bolts can be all over the place in terms of rating. I have never encountered one harder than the Horrido 4.8 bolt tho. I think the grade 5 bolt you have are unusually hard ones if they are harder than the 4.8. The hardest 1/4 G5 bolt I've bent was always slightly easier than the Horrido 4.8 bolts at the same length.

matek Posted July 3 Share Posted July 3 Have you bent them both to sub 2", or are you talking about the start of the kink? Because if the latter, it's possible that the thicker stuff is harder to start. Quote Link to comment Share on other sites More sharing options...

Because if the latter, it's possible that the thicker stuff is harder to start. Although G5 bolts can vary a lot I think 420 lbs seems like way out of range. I mean that's where you start to find red nails. So my guess that rating is not comparable to the numbers Horrido puts up on his website. Also like you said the kink will be harder on the 4.8 bolt. Even more if you're doing double overhand. The 4.8 bolt is 180 mm long and the G5 bolt I assume is 6". That 4.8 bolt will always be harder to kink under those circumstances and the G5 bolt will always be harder to crush. The 4.8 bolts from Horrido is actually the least springy material I ever bent, while G5 and G8 bolts are the most springy.

dean_redzic Posted July 4 Author Share Posted July 4 Just going off of this spreadsheet it says a silver grade 5 1/4" by 6" with the NY stamp is 420. Could be way off though. I am only bending DU at the moment so the initial part could be the issue Quote Link to comment Share on other sites More sharing options...

I was surprised as well, but I checked and apparently, people rated G5s even higher than that. 19 minutes ago, dean_redzic said: I am only bending DU at the moment so the initial part could be the issue I meant the very start (not up to 30 or 40), it will just give up after that (unlike the G5, hence the higher rating).

Challenge with these kind of bolts are always the sweep and crush. Edited July 4 by Fist of Fury Quote Link to comment Share on other sites More sharing options...
diziet Posted July 5 Share Posted July 5 Most grade 5 bolts should range between 305-350 for a 1/4 inch x 6 inch bolt. It's possible that some manufacturers use slightly stronger steel, but 420 lb is about where G8 bolts come in. I've rated g5 bolts at close at 400 so I can believe there is variability there. It really depends on the manufacturer and the batch. Worse case, rate a few yourself compared to another known product. Re: horrido's bolts, the 7 inch for me is a lot tougher on the kink especially when using single wraps. Like Sid said it's really a big inch!

dean_redzic Posted July 9 Author Share Posted July 9 (edited) Thanks for the input everyone. If I dedicate my training to the 7" length will 6" require much training to get back into the flow of things? Does 7" transfer to 6" length? It would seem that training 6 inches doesn't directly transfer to 7 inches Obviously specificity is king, but just curious if there is transfer and If I should be spending more time on longer bars Edited July 9 by dean_redzic Added extra info Quote Link to comment Share on other sites More sharing options...
