BCT Large Flange Multigrip Splined body 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.
