I'm new to using these and trying to do a little metal work, as the net is confusing me not helping me. all articals and video's tend to talk about taps mostly and not about how to match the right die to the correct tap Here's my question.
I have a nut that fits a 1/8BSP28 tap perfectly, what diameter should the bolt be (unthreaded) and Also what die would i then use? the 1/8BSP28 die??
@MrBoggles yes. 1/8 is the mean diameter of the fastener. 28 is threads per inch. BSP is british standard pipe. basically a metric pipe tap... use a thread guage to determine the thread pitch of your bolt. you would then use the correct die or tap with the same numbers on them. 6 x 1.00mm bolt uses a 6 x 1.0mm tap to fix the hole and 6 x 1.0mm die to fix the fastener {bolt} us and british standard use threads per inch TPI. your bolt if an inch long would have 28 threads on it.
great video mate however something that you failed to mention tho is always clean the threads whilst tapping or dieing You do this by reversing the tap or die evry three turns forward you turn the tap or die in the reverse rotation to ensure a good clean thread whilst proceeding to tap or die this causses less stress on the tools and a good clean thread! other than that very good video enjoyed watching it :)
heres a handy tip, for the hole size the general rule is, thread size minus the pitch equals the size of the hole you need. eg an 18mm thread with a 1.5mm pitch = a 16.5mm hole, as for the outside thread i usally make the bar 0.2-0.3mm less than the thread. eg for an 18mm thread i'd turn the bar to 17,8mm,
I have managed to thread/strip the thread on my motorbikes rear shock mount bolt which is ofcourse welded as part of the bike frame! I assume i'll need to buy a tap & die set and use the appropriate die to rethread the bolt :)
anyway, cheers this is exactly what i needed to learn

Terrible video. Once again, can't actually watch the video because the subtitles take up the entire freaking screen.

Good stuff - Thankyou.
Is the oil a specific type - Would 3 in 1 type oil do the trick?

I usually use WD-40 when I need to grease nuts and bolts.

Do the taps only work in wood, or can they be used with other materials, too?
maggoli67 3 years ago
taps are used on metal, plastic, and with the correct type of tap, wood.
Dreadeye55 3 years ago
you'll rarely need to use tap & die on wood anyway.
if you want your screw to fit tightly in the wood - you'd just get a screwdriver on it and drive it in.
that way it'll fit tight as a goose's arsehole.
