Anti-roll bar bolts

[Roger Ford]

Anyone know the size of the bolts for front anti-roll bar on an imperial chassis?

About to put a Namrick order in and I thought I ought to get some of these - they get undone a lot and also it would be handy to have spares because it's not unknown for people to lose them (from forgetting to tighten them after changing ARB).

I don't know the size but you are likely to need 3/8 UNF, 5/16 UNF or 1/4 UNF. These have 9/16, 1/2 and 7/16 heads, respectively. The first 2 are most likely. I don't know about lengths, but that's the easy bit to fix with a hacksaw and a file.

 

IMO one of the best investments anyone can make with a 7 is a selection of fasteners in the above sizes and a few metrics to match. It makes maintenance so much easier when that ratty fastener that you've had to brutalise to get apart can be tossed in the bin and a new one screwed in easily by hand.

Roger,

Just measured our's and they are 1 1/4" X 5/16" U.N.F.

Thanks, AP.

 

Boss, I've always kept a good selection of metric fasteners, and I have been wondering whether to try to get a UNF selection as well.

 

The "Mixed UNF pack" from Namrick has been hovering in and out of my basket. But I'm rather afraid that will have lots of not-useful sizes. Perhaps you're right and I should just pick my own selection in various sizes.

TBH if I were you I would buy the Namrick selection pack. 450 for £16, good enough. The most popular sizes on our cars are the ones I name above and they will cover most eventualities. I would imagine that 80% of that box will be those 3 sizes. It's the UNF answer to M5, 6 and 8, it covers almost all general fasteners on light vehicles.

 

I find spare fasteners essential, I wouldn't be without mine. One thing I do find is how fast they go down, especially if you are making something. You may have 50 x M6 nuts and bolts, use a couple here and there and...oh. Run out. I'll have to use an M5 and a washer.

Ignore - stupid imperial measurements.

 

Good plan, BOSS, I'll get the combination pack.

And this one.

Roger, if I were you, I'd buy the mixed imperial pack, then top-up with the most common used ones. That way, you'll be covered for most eventualities.

[CharlesElliott]

Roger - I bought 20 odd of them so you can have some of mine.

[Roger Ford]

Thanks, Charles.

Mine aren't, they're 1 1/2" x 5/16" UNF.

 

Anyone need 4 x 1 1/4 inch 5/16 bolts? Oh well, they were only a quid.
