Manfrotto 118 Universal Stud 16mm

We use hundreds of these, usually screwed in one side of Manfrotto magic arms, or in Manfrotto super clamps, with the 3/8" BSW thread visible, which suits audio equipment . It is reversible, if you prefer 1/4" thread for cameras etc. We like the hole in the middle, which is useful for attaching safety bonds or cable ties, and we like that they are shorter than the "full length" spigots, because the reduced leverage means that they are less likely to snap off when subjected to shocks (removing the remains of snapped spigots from magic arms is not fun...)
