Kupo 5/8" to 3/8"-16 Adapter Stud

This solid brass adapter connects 5/8" stud equipment to 3/8"-16 male threads. It suits photographers and videographers who need to mount light stands, reflectors or similar accessories onto camera or lighting gear. The precision-engineered fit works with the Convi Clamp System for quick, secure attachment in professional setups.

Thread limits and mounting constraints

The adapter only bridges a 5/8" stud to a 3/8"-16 male thread; it cannot connect other thread sizes or stud diameters without additional hardware. Load capacity depends on the weakest component in the chain, so the stud, clamp and accessory ratings all govern the practical limit. Brass construction resists corrosion but can deform under extreme torque.

Replaces makeshift couplers and loose adapters

Swapping improvised shims or worn threads for this machined stud eliminates wobble and slippage during shoots. The upgrade is worth it when a stable, repeatable connection matters more than the minimal 70g weight penalty. It does not help builders who need a different thread pitch or a larger stud diameter.

Questions about this item

Should I pick the 5/8" stud or the 3/8"-16 male thread version?

This single adapter has a 5/8" stud on one end and a 3/8"-16 male thread on the other, so you do not choose between versions; it connects both standards at once.

How much weight does the 0.15 lb adapter add to a light stand?

At 70 g it adds negligible mass, keeping a lighting rig portable while the solid brass body maintains a rigid, wobble-free joint.

What does the 3/8"-16 thread actually fit in practice?

The 3/8"-16 male thread mates with any standard 3/8"-16 female socket found on light heads, clamps, arms and the Convi Clamp System.
