Bulge Control Technology, (BCT) is a new and unique design of rivet nut that is changing the face of the fastening industry. Rivet nuts are by no means a new concept, but BCT’s patented design removes the limitations that prevent standard rivet nuts from being used in a variety of common application settings.
An interesting application was recently received. A customer wanted to install an M5 rivet nut into a tube (12 millimetre OD, 10 millimetre ID), but all the standard rivet nuts they tried failed due to the tight radius and the reduced blind side clearance. Basically they were too long.
A reduced length BCT was installed which overcame these issues. Reduced length BCT is a new product being launched soon. This particular version of the product is clearly for use where either blind side clearance is restricted or where blind side protrusion must be kept to a minimum. However, owing to the unique method of manufacture this product still yields thread strength suitable for use with grade 8.8 bolts.
Tubular steel is used in great volume. The size used in this case is one of the most common sizes in Europe
and is frequently used in the manufacture of items such as metal furniture. If you have a requirement which conventional rivet nuts cannot cope with we almost certainly have a product which can be tailored to your requirements.
BCT rivet nuts can be installed into almost any material including GRP, most plastics, wooden board, carbon composites as well as all metals. BCT is available in steel, aluminium, brass and to order in 316 stainless steel.
