0.75" Short Square Threaded End Connector

DragonPlate square threaded end connectors provide an easy and robust method for connecting carbon fiber tube ends to each other and various accessories via a 1/4"-20 thread. DragonPlate short threaded end connectors are similar to our standard threaded end connectors, except they have been designed to reduce the connector's weight by shortening its length.

One of the primary concerns when bonding metal fittings to carbon fiber tubes is that the metal component, when subjected to temperature reductions, will shrink significantly more than the carbon fiber tube. To eliminate this problem, our patented connector incorporates a slotted design, which has a two-fold effect. First, the slots allow the aluminum to contract without as much change in the nominal dimensions of the insert. Secondly, the slots provide compliance to the part, which further alleviates peel stresses by prohibiting the aluminum part from imparting as much peel force on the adhesive layer. Additionally, this design features a ridged outer surface. This further strengthens the bond inside the carbon fiber tube by placing more epoxy in shear (and most structural epoxies are about 100 times stronger in shear than in peel). 

This combination of form, function, and resistance to thermal delamination makes our DragonPlate tube connectors a versatile and robust option for many projects. Each connector also comes with a foam plug to contain adhesive and enough bond line control micro glass beads to ensure a proper bond fit. Accepts 1/4"-20 Thread. 0.25" and 0.75" stud length options available.
