3.5" Extra Long 5/8" Baby Stud

This 3.5-inch extra long 5/8-inch baby stud connects grip hardware with a 3/8"-16 male thread on one end and a 5/8-inch receiver on the other. It is built for photographers and videographers who need to mount lights or accessories onto grip heads, convi clamps or articulating arms. The aluminium construction keeps the rig light while the knurled neck resists unwanted twisting during use.

Thermals noise and power draw

Passive aluminium construction means there are no fans, no moving parts and no electrical draw. The stud adds no heat or noise to a lighting setup and requires no power supply or battery. It simply transfers mechanical load between grip components without affecting the thermal or acoustic environment of the shoot.

3/8"-16 male thread length 25.4 mm

The male thread measures 25.4 mm in length and is secured by a fixed pin, determining how deeply it engages with female 3/8-inch threads on clamps or arms. If your accessory needs a shorter or longer thread engagement this stud will not match. Builders who need a different thread standard or a non-pinned connection should look elsewhere.

Questions about this item

How do I install the 3.5" baby stud so the 3/8"-16 male thread does not spin loose?

Screw the 25.4 mm long male thread into the female 3/8" socket until the knurled neck seats, then tighten with a spanner on the flats so the pin locks the thread and prevents rotation.

What part of the stud will need checking or replacement after repeated rigging?

Inspect the knurled neck and the pin that fixes the thread; if the knurling wears smooth or the pin loosens, the stud can twist in the receiver and should be swapped out.

What is the first limit reached when the stud carries a heavy light for long periods?

The 3.5 inch aluminium shaft will bend before the 5/8" receiver or 3/8"-16 thread fails, so watch for deflection at the centre of the stud.
