Kupo 38 to 16 Thread Screw 25.4mm Set of 5

The Kupo KS-138 is a set of five steel 3/8"-16 threaded adapters, each 25.4mm (1") long and weighing 80g total, that convert a 3/8"-16 female thread into a 3/8"-16 male thread. They tighten with an Allen key or wrench, making it easy to mount a tripod head or similar equipment onto a fixture that only offers a female 3/8"-16 receiver in an awkward spot.
