MADE IN UK PLEASE READ CAREFULLY IT MAY SAVE YOU SOME MONEY Plier type tools rely on the strength of your grip, which is ok for the smaller aluminium rivnuts but if your fitting un-serrated or larger steel rivnuts you may find the rivnuts turn when fitting the final screw/bolt. Using our tool you can increase the amount of torque applied when setting the rivnut thus reducing the chance of the rivnut turning. Instruction for use. Use a 13mm open ended spanner to hold the bush and tighten the nut with a 13mm spanner. However if the rivnut just turns in the hole DONT PANIC ! Use a 13mm spanner to hold the bolt and tighten the nut with a second 13mm spanner. International Buyers please ask for extra cost of postage.
