Lewis Posted July 13, 2014 Share Posted July 13, 2014 Does anyone know the part number for the bolts which are used on thick mushroom/one peice halfshaft-drivemembers on 10 spline rrc rear axle? Quote Link to comment Share on other sites More sharing options...
Team Idris Posted July 13, 2014 Share Posted July 13, 2014 I don't know the number, but they are 3/8" unf. (but you probably already know that, so I'll throw it in here for anyone who wants to bypass the dealership ) Quote Link to comment Share on other sites More sharing options...
Lewis Posted July 13, 2014 Author Share Posted July 13, 2014 That's good to know, thanks I could always just go outside and pull one out to measure, but it's far easier to order them from the sofa Quote Link to comment Share on other sites More sharing options...
western Posted July 13, 2014 Share Posted July 13, 2014 Visit your local engineering fasteners stockist with the thread type & one bolt, will be cheaper than buying the genuine bolts Quote Link to comment Share on other sites More sharing options...
Davo Posted July 14, 2014 Share Posted July 14, 2014 No doubt this will arrive too late for you, as I'm still on my training wheels. (Note to mod: can I post all on my own now, please?) 279146 is the part number . . . http://www.brit-car.co.uk/product.php/78807/1608/bolt_3_8unf_x_1_7_8__3_4__thread . . . I'll assume those are accurate dimensions. Quote Link to comment Share on other sites More sharing options...
Lewis Posted July 14, 2014 Author Share Posted July 14, 2014 Part number is 279146 Bolt is 3/8 UNF x 1 7/8" long, 3/4" hex Quote Link to comment Share on other sites More sharing options...
Daan Posted July 15, 2014 Share Posted July 15, 2014 I always use capheads for these, as you are going to want them FT. Ask me how I came to this conclusion. Daan Quote Link to comment Share on other sites More sharing options...
Lewis Posted July 15, 2014 Author Share Posted July 15, 2014 Where did you get yours Daan? I think I'll be reusing the originals for the short term as time is running out to source replacements Quote Link to comment Share on other sites More sharing options...
Daan Posted July 16, 2014 Share Posted July 16, 2014 most generic, local bolt suppliers can do what you want, for the more awkward ones, I have used these guys: http://www.namrick.co.uk/ Also, these guys never disapoint: http://www.tridentracing.co.uk/racing-supplies/index.asp?page=nas-1100-bolts-tecnical-spec-46 Since it is unf bolts you are looking for, I linked to the NAS bolt page, which is aircraft spec. They are better strength than 12.9 grade capheads but a bit more spendy. they would also do the capheads though, and loads of other goodies. Its a double edged sword with NAS bolts, as the strength is better, but the thread engagement is less (less threaded length), which could cause them to strip the thread in the hubs earlier. I would have a good measure of the bolt lengths, as I found I could get away with a longer bolt, and so get the bolt to shear on the shank, rather than the thread. But I am on metric hubs, with m10 bolts. Quote Link to comment Share on other sites More sharing options...
Lewis Posted July 17, 2014 Author Share Posted July 17, 2014 Thanks Daan, ordered some 2" cap heads, I'll cut the tips off if required Quote Link to comment Share on other sites More sharing options...
