Installation Method
1 2 3 4
Using your prefered type of installation tool. KJ60 air tool and N200 hand tool shown for reference only.
Ensuring that you are using the correct grip size rivet nut for the panel you will be installing into, screw the rivet nut fully on to the tools threaded mandrel.
Follow the instructions specific to your tool to set the correct stroke length for proper rivet nut placement. Fully insert the rivet nut into the hole in the work piece.
Ensuring that you are holding the tool perpendicular to the work piece, operate the tool to set the rivet nut in place.
Unscrew the threaded mandrel from the rivet nut. That’s it. Your rivet nut is now installed.
To ensure that the rivet nut performs as intended it is important that an optimum bulge is formed.

Info
BCT Large Flange Multigrip is a new type of high performance rivet nut designed to streamline rivet nut usage and provide much improved performance over conventional rivet nuts.  BCT provides a strong captivated thread in panels and is ideally suited to applications where only one side of the panel is accessible such as box or tube section. BCT Multigrip offers a much wider grip range than conventional rivet nuts. One nut will cover two grip ranges in the smaller sizes and up to 4 grips in larger sizes, thus reducing inventory items. BCT features a bulge control design which produces a larger bulge formation than conventional rivet nuts and controlled upset points, which allows for perfect installation even in oversize or irregular holes. They can also be used in softer or brittle materials such as composites or sandwich sections for example. Available in thread sizes M4 to M12, in RoHS compliant heavy duty electro zinc plated steel (giving 96 hour salt spray protection), 304 stainless steel, aluminium and brass, they can be installed into panels as thin as 0.5mm and as thick as 18mm. They can also be manufactured in grip ranges to suit your exact application requirement.   Requiring the same installation tooling as conventional rivet nuts, tools range from very low cost hand tools for low volume, to air powered automatic installation guns for high volume applications.   BCT has an advantage over other captivated fasteners because they can be installed on site or used for repair work to replace a previously installed fastener that has failed. The advantage of installation from one side of the application means that access to the back of the panel is never required. BCT is a registered trademark of BBA srl.
