If it sthe ball hitch your bolting on: M16x 2.0mm pitch about 50-65mm long if using a spacer.

They need to be high tensile aswell(have "88") on top of the bolt head.

Fitters normally use locking washers as oppose to nyloc nuts.

These bolts can be purchased from car shops, caravan bits supliers etc.

Or if you mean the ones to mount to te recovery points either side they are M12 x about 40mm IIRC, get nyloc nuts and also get bolts (partially threaded) as apposed to set screws (fully threaded)

The most important thing to consider is you get bolts that have a sufficient shear tolerance and always use something to lock them be it a spring washer or a nyloc :thumb2

I have to disagree with the definitions of set screw and bolt (in the nicest way ) dont worry about thread length along the bolt and probably best if you dont ask for set screws. Wilkopedia can help

I do sell em for a living- fastening are my main line, plenty of catalogues here that agree with what I'm saying - or Namrick website HERE

If you ask for set screws in a proper fastenings supplier they will know exactly what you mean - if you go to B&Q they won't have a clue.


Wikipedia however is far from always right.

Wikipedia however is far from always right.

I would trust "wikipedia" as much as the "The Sun,Daily Star or The Sport".!
Its a bullshit web site & don't understand why people take it as gospel :doh

No one said wilkopedia is always right....read the post

The amount of thread on the length of a threaded item does not define whether its a set screw or bolt.

I've just fitted two bolts (their description on the receipt) from screwfix onto my car tonight to hold the new spot lights on. They've got no plain portion at all
I've also got some coach bolts from screw fix in the shed theyre labelled as bolts not screws and amazingly are 100% threaded

But in the face of such expertise I aint going to argue

And thats from a fully qualified (and certified :naughty but expired :thumb2 ) aeronautical engineer who had to pass exams on what is a screw amongst other things :thumbs

What is far far more important on this thread is that the advice reflects the correct length (to leave the right amunt in safety) the correct lock (nyloc, spring washer) and the correct spec are used (high torque may look like it fits but its shear strength could be zilch) .

Depends how you use it doesnt it ....... if youre gullible enough to base a decision on one source you will look a twat :augie
