9.Solutions 3.5 inch Baby Pin set

The 9.Solutions Bay Pin Set consists of two 5/8"" pins with a 3/8""-16 female and a 3/8""-16 male thread. These pins are a handy accessory for mounting devices with a 3/8 "" male or female thread. The pins can each be used separately in, for example, clamps with a 3/8"" threaded connection. You can screw the pins together to make a longer 5/8"" mounting pin.
