can someone explain what these rivnuts to me? i know and have used rivets and found myself going through alot of them
just wanted a yes or no answer to one of my above questions, can i tap (i think im using the right pharse)/ make a thread in box section?

Hi Alex
See below....

Fork N Torque will use about 200 to mount armour

You could tap in a thick walled box section. A guideline for treads depths.
In steel and Titanium bolt size. M4 is perfectly possible in a 4mm thick plate (or box section wall).
In ali and other soft alloys,boltsize *2. An M4 needs 8mm of flesh.
Bronze and simular boltsize *1.5
thanks for that tony, so from what i can gather i would put these into the box section? and am i right in think i use a bolt to secure the whole thing together?

hi alex
All ya gotta do is drill a 10mm hole in one side (outside) of box section...insert rivnut then if ya have the special tool just close the jaws...if ya dont have tool follow instructions on addy given.....i also give each one a couple of tack welds to really make sure it dont come loose !!

had a meeting today with a local metal fabrication company, about sponsorship very interested but said they dont use ti much but have loads of stanless steel still good right?
also going to help with welding cutting....
very happy now, alex
just done some calculations couple of kgs over with 3mm stainless steel, does someone know the density of stainless steel?
thanks alex
search on google. It wont be far off mild steel/hardox

Stainless steel is as heavy as hardox. Take 8kg dm³ as guideline. Normal steel is a bit lighter with 7.8kg dm³
