Gripper42004 Posted November 19, 2003 Share Posted November 19, 2003 Of who we know how many people can "u" a grade 5 1/4in. x 6in. bolt? I would guess less than 10 people can do it,but I could be wrong. Quote Link to comment Share on other sites More sharing options...
SHRUG Posted November 19, 2003 Share Posted November 19, 2003 I have bent 6 grade 5 1/4in. X 6in. bolts into a U shape so far. I bent my first one last week. I then bent 2 on Monday of this week, 1 on Tuesday, and 2 more today. I think I am going to take the rest of the week off of bending until Saturday because my hands are pretty well toasted. By the way I do have myself bending a grade 5 1/4in. x 6in. bolt into a U on video. I tried bending a grade 8 1/4in. x 6in. bolt into a U this morning and I put a decent kink in it.

Razorman Posted November 19, 2003 Share Posted November 19, 2003 How are you finding out the "grades" of these bolts? They're not listed on the box when I get em from Lowe's. Quote Link to comment Share on other sites More sharing options...
SHRUG Posted November 19, 2003 Share Posted November 19, 2003 Razorman, A grade 5 bolt will have 3 lines on it's head, it will also read JH on the head. A grade 8 bolt has 6 lines on it's head and they are usually a different color than silver. I have seen two different brands of grade 8 bolts one brand is gold colored and the other brand is almost black. Quote Link to comment Share on other sites More sharing options...
Razorman Posted November 19, 2003 Share Posted November 19, 2003 The bolt I have here has BL 307A written on it. Any clues? Sorry if this is the wrong forum, it's just I'd love to know how to gague strengths of materials before buying them. Quote Link to comment Share on other sites More sharing options...
SHRUG Posted November 19, 2003 Share Posted November 19, 2003 You can get a metal bending chart at http://home.insight.rr.com/strongman/index.html, when you get to the home page click on bending steel and get the chart that is ordered by yeild strength. I do not think that the strengths listed are exact but they are darn close. Quote Link to comment Share on other sites More sharing options...

Sorry if this is the wrong forum, it's just I'd love to know how to gague strengths of materials before buying them. If the bolt is without lines on its head, it's a grade 2 (the easiest).

pexter Posted November 20, 2003 Share Posted November 20, 2003 (edited) Hey,Tommy I have just recently bent,for the first time,a grade 5 bolt 1/4"x 6" A few weeks ago.I took a little bit of a break from bending these past few weeks due to the fact of real bad soreness in my ligs.I also did some scrolling with some 1/2"x 1/2"x4ft square stock that same week.Got 2 full circles out each of the 6 of that I scrolled. he is a mighty God!!!

Jonathan McMillan Posted November 20, 2003 Share Posted November 20, 2003 Shrug, Great info on the markings on bolt heads I think this should be added to the FAQ section of the board!! Jon@han Quote Link to comment Share on other sites More sharing options...

bencrush Posted June 28, 2009 Share Posted June 28, 2009 This is a nice blast from the past. Shows you how far the board as a whole has come in just 6 years. Where will the records be in another 6? Quote Link to comment Share on other sites More sharing options...

gumpster Posted June 30, 2009 Share Posted June 30, 2009 This is a classic! Reminds me of the post I read by Gazza asking about getting from the Grade 8 to the Red. Bending has made huge leaps in the past few years. Quote Link to comment Share on other sites More sharing options...
gazza Posted June 30, 2009 Share Posted June 30, 2009 We all have to start somewhere i can well remember getting my 1st g5s and g8s off of PAT and then busting a bollock to bend it the g5 but at the end of the day im still amazed that the human body can at times be stronger than steel People say bolts and steel etc cannot or should not be bent by human hands sometimes you just have to prove otherwise Quote Link to comment Share on other sites More sharing options...
