    whats this gap check paste called ?

    per pic.

    its a paste like substance used to detect interface contact between a bolted joint.

    whats it called.... I know the Thai name but that is not helping me find the stuff locally.

      Or engineer's blue.
      Lots of minis & mokes including a G13b powered Sports Sedan, a couple of Swift Gtis, a Goggomobil, Porsche 928S, Polo Gti, BMW 540i, a WRX and a few others.

            That doesn't look like any engineers blue I've used. It's always been a liquid, not a thick paste like that appears to be.

                It’s basically Prussian blue with a thickener. Problem is in this case you are using it to determine torque, which means you will need to know the viscosity of the bluing paste first.

                  Nah nothing to do with determining torque.

                  Cannot go into specifics but the 27.5 was dictated by the customer as that is the torque of the nut runners they use for line fitment.

                  Our solution was to simply torque the bolts more (its an M12 1.75 bolt) but that would require them to add an extra tool to the workstation and they wont have it so put the problem back onto us.

                  Just need the paste to perform some in house tests when I change the angle of the mounting Boss, In CAD land the interface is 100% but in real life we look to be about 0.02 degree off (Welded thin wall stainless, who woulda thought there would be some weld pull!!) so need the paste to check interface @ 27.5 after I make the change to show them 100% contact.

                    Ah, fair enough. Looked like from the photos it was being used to tell fastener torque and gaps a la bearing worms.

                      Nah nothing critical, its a connecting joint on a 3pc sports bar (Ranger FX4).

                          27.5Nm seems low enough that they will just fall off, looked it up and Google says 100Nm is typical for M12x1.75.

                          Something for the PVT lads to sort out I guess.

                              So's.... ended up buying 500gm of orange lead oxide powder and mixing it with hydraulic fluid.

                              Worked perfect and ive enough to last me atleast 11tybillion lifetimes!!
