cols110 Posted March 6, 2006 Share Posted March 6, 2006 G`day all, my new toy is an 02 110, I want to know if 4 front bumper bolts are high tensile or not, the bolts are a reduced head with some markings on them, but I cant read the markings, that indicates to me that they might be, but the thread is definately a course thread which indicates that they might just be normal bolts not high tensile. If any one can shed some light on if TD5 bumper bolts are good or bad I`d be greatly appreciative. Thanks Quote Link to comment Share on other sites More sharing options...

Thanks the thread profile won't have anything to do with whether it's HT or not, is there any marking at all on the bolts? three circles on the flats of the hex or anything else?

cols110 Posted March 6, 2006 Author Share Posted March 6, 2006 Can`t really tell, because they have been painted over and it is an air-con grill which protrudes over the bolt heads. I think there might be an M and possibly an A or V, there definately is`nt an 8.8, sorry its not much help. Quote Link to comment Share on other sites More sharing options...

cols110 Posted March 6, 2006 Author Share Posted March 6, 2006 Ralf thanks mate, now we know they are M10x120 bolts. All we need to know know is how strong they are. As I want to bolt a couple of these to the bumper. Quote Link to comment Share on other sites More sharing options...
minivin Posted March 6, 2006 Share Posted March 6, 2006 Have looked in my notes but it only covers the British Standard 'A' Series, without delving into BS, maybe BS has an 'M' Series for Metric which will help you determine the spec?

As I want to bolt a couple of these to the bumper. The standard fit bolts should be upto use with those, IIRC my husky & bumper still have the standard fit bolts & I've put lots of hauling weight through them, I would think the standard bolts are HT 8.8.

western Posted March 6, 2006 Share Posted March 6, 2006 I didn't say assume anywhere can't find any info about non ht bolts in the workshop manual, it gives info on ht's between 8.8 to 14.9 Quote Link to comment Share on other sites More sharing options...
cols110 Posted March 6, 2006 Author Share Posted March 6, 2006 My gut feeling is that they are HT, but I don`t want to discover that they wer`nt during a kenetic recovery. Thanks for all the info so far. Quote Link to comment Share on other sites More sharing options...

western Posted March 6, 2006 Share Posted March 6, 2006 Col, in my RAVE disk Defender winch fitting info, they show removing the 4 standard bolts from standard bumper & then refitting the standard bolts through the winch bumper, no mention in the info about changing bolts for different spec ones.

Mark90 Posted March 6, 2006 Share Posted March 6, 2006 Col just replace them with some HT bolts (min 8.8) then you know they are up to the job. Mind you i suppose it's not a 10 min job with an A/C grill. Nice looking truck BTW Quote Link to comment Share on other sites More sharing options...
cols110 Posted March 6, 2006 Author Share Posted March 6, 2006 Thanks Ralph, that gives a pretty good indication. Mark, I might end up doing that, just to be on the safe side, but if the origional ones are up to it seems a waste to chuck em out. Yep I dont mind the look of the new truck either.

BogMonster Posted March 6, 2006 Share Posted March 6, 2006 Chuck them away and replace them with 4 x BH110261L bolts with a proper sized head on them, you can get a sensible sized socket on those (17mm I think) and get them good and tight and I'm pretty sure they are 8.8s.

cols110 Posted March 7, 2006 Author Share Posted March 7, 2006 Thanks all, I think I might end up binning em all to be on the safe side. Yep Black Rat hooks, seem em on another 110 out here and they look nice fitted. Quote Link to comment Share on other sites More sharing options...
cols110 Posted March 7, 2006 Author Share Posted March 7, 2006 OK problem solved, I pulled out a couple of bolts and cleaned the heads up and they are indeed grade 8.8 bolts. Many thanks for all your info. Quote Link to comment Share on other sites More sharing options...

JST Posted March 8, 2006 Share Posted March 8, 2006 i was going to say my bumper is held on by MP bolts and they are 8.8, but i see we have now estb that so i wont bother mentioning it............ Quote Link to comment Share on other sites More sharing options...
Se7enUp Posted April 17, 2007 Share Posted April 17, 2007 Sorry to bounce this back up to the top, but on a similar note....... What do these bolts screw into when fitting a winch bumper? I've just bought a 2nd hand winch bumper and am hoping to fit it this weekend. I've just tried to remove the old bumper and 3 bolts came out - 1 snapped off 1/2 way down in the chassis (Bummer!) It looks like getting the rest of the bumper off will involve getting busy with the angle driver! Anyway, I can get one end of the old bumper away from the chassis and it looks like the bolts screw into a threaded hole in a rectangular plate which is welded onto the bottom bracket on the old bumper. My new bumper doesnt have anything like this. Can I just use standard nyloc nuts (if they will fit) or do I need to buy some kind of plate with captive bolts to screw into?
