Connector Nuts

Trojan Special Fasteners Ltd routinely manufactures connector nuts to customer's requirements in multiple material and finish combinations. We manufacture a range of sizes of connector nuts in almost whatever length you require.

Connector nuts are also known as connecting nuts, connection nuts, coupler nuts, joining nuts, long nuts, studding connector nuts and coupling nuts. Such nuts are longer than normal nuts and are used to couple two threaded bars (studding) together.

They are typically available in two forms, one with a hexagon profile and one with a diameter profile:

Hexagon Connector

Round Connector

Typically they are 3 times the length of the inner diameter, but we can machine other sizes, just ask! We can manufacture these in a limited number of sizes with a square profile if needed - but these are extremely rare. We can make almost any combination of internal and external diameter or profile you're looking for within available material specifications and finishes. At times customers ask these to be partially threaded on each end, sometimes with mixed thread sizes, pitches and a combination of left hand on one side and right hand on the other. Typically these are known as reducing coupling nuts.

In addition to standard preferred sizes, we also manufacture non preferred sizes and non standard or special thread and nut forms.

Trojan special fasteners can build additional features into fasteners, like collars, castellated, slotted portions and also cross drill and tap these:

We can machine connector nuts to your dimensions, drawing or sample in a multitude of sizes, materials and finishes.
