Standard Width Screw-Knob Clamp
Install on ball stems with male stud threaded 3/8"-16.
Traditional screw-knob clamps are tried & true and can deliver slightly greater clamping force than our Lever Release clamps. Clamps have dual mounts: center socket is countersunk on top but also threaded 3/8"-16. Mount by spinning onto an exposed threaded post or with flat head screw from above (accept M6 or 1/4"-20, not 3/8"). These clamps are appropriate for mounting on:
B2-Pro is 60mm (2.36") long, one central countersunk 3/8"-16 socket, two outboard 1/4"-20 sockets spaced 1.2"/30mm apart on center, captive knob, centering index marks, 3.8oz/116g
