Dual Threaded Adapter Screws

Technical Data Sheet # CMM 14

We carry a full line of Dual Threaded Adapter Screws which have a different thread on each end. These threaded adapters will match all of our Coordinate Measuring Machine evaluation and fixture building devices to the threads in the table of any C.M.M. or competitor's pallet system.

The short version of these threaded adapters (Table #1) have an overall length of 1.5 inches (38.1 mm) and each of the threads is 3/4 inch (19 mm) long, except the 1/4 inch-20 to M10 x 1.5, where the 1/4 inch diameter is only 1/2 inch (13 mm) long.

Because these Dual Threaded Adapter Screws get such heavy use, we machine a reduced-diameter on the very ends to avoid damaging the thread.

The two threads have an undercut in the center to allow either of the threads to be tightened fully without any chance of binding.

The Dual Threaded Adapter Screws will not rust because they are manufactured from a very corrosive resistant type 18-8 Stainless Steel.

The highest quality threads with increased tensile strength are produced by cold rolling the thread forms.

There is a screwdriver slot provided at the end of each thread of the short version and in the long threaded end of the long version. With the aid of a coin or screwdriver, the Dual Threaded Adapter Screw can be securely tightened into its mating part.

The long version of these Dual Threaded Adapter Screws (Table #2) have an overall length of 2.5 inches (76.2mm). The table, or short end thread, is 3/4 inch (1.9cm) long; and the M10x1.5 thread is 1.75 inches (44.5 mm) long, except the 1/4 inch-20 to M10x1.5, where the 1/4 inch diameter thread is only 1/2 inch (13mm) long.

If one of these fourteen combinations does not meet your requirements, we will be pleased to supply any other combination on special order.
