These pre-cut and pre-threaded tubes are ideal for fabricating support struts and linkages. Black powder-coated aluminum is light weight and looks great.
Each tube has right-hand (conventional) 1/4-28 UNF threads at one end and left-hand (reversed) 1/4-28 UNF threads on the other for quick length adjustments. Add 1/4-28 male threaded rod ends and jam nuts (each sold separately) to make a complete strut or link assembly. The 7/16" hex profile matches the hex size on AN316-4 1/4-28 Jam Nuts for ease of use. The end of the tube with left-hand threads has a groove for quick identification. Hex measures less than 3/4" point-to-point. Sold individually.
