I’ve recently purchased a second hand tow bar and was told to get a tap to clean out the m14 holes at the rear, does anyone know what pitch these bolts are please, thanks

Its unlikely to be worth your expense to buy a tap, they can be quite expensive, just cover a bolt with oil, run it in and out and wipe it off, repeat a few times cleaning the thread out with brake cleaner or even wd40 would do the job.

You could also try cutting a slot in the thread along the length of a spare bolt and run that through, helps to scrape out the crud in the female thread.

Hi, you might be best getting hold of a thread pitch guage or pop to any engineering firm & they can measure the pitch for you, before running bolts through, std pitch is probably 1.75 or 2.00. Having just done radius arm bushes on mine I know the m16 bolts are 1.50 fine pitch items (so they can take a higher torque) which might be the same for other 'high' load items like tow bars.
