Overview

The Manfrotto #184 is a small piece of grip hardware with a very specific job: bridging the gap between a 5/8-inch stud and 3/8-inch threaded mounts. On one side, it presents the familiar 5/8-inch pin used by most professional light stands and combo stands. On the other side, it offers both a 3/8-inch male thread and a 3/8-inch female thread, so accessories that expect either configuration can be attached without hunting for a second adapter. For photographers and videographers piecing together lighting rigs, modifiers, or accessory arms, it's the kind of low-profile component that quietly keeps a setup compatible.

This adapter sits squarely in the practical, problem-solving category of studio gear. There are no moving parts, no controls, and no setup beyond threading it into place. That simplicity is the appeal — it's a part that disappears into a build once installed, leaving the stand, head, or modifier to do the visible work. The Manfrotto badge places it among the brand's broader grip and support ecosystem, where consistent thread standards make mixing and matching components more predictable. For owners who already work within Manfrotto's lineup, the #184 is a sensible spare to keep in the gear bag.

Frequently Asked Questions

A 5/8-inch pin plus both 3/8-inch male and 3/8-inch female threads. That gives you three mounting options in one piece for studio and lighting setups.
Not directly. The #184 only addresses 5/8-inch and 3/8-inch fittings, so a separate 3/8-to-1/4-inch reducer would be needed for 1/4-inch hardware.
No. It is a passive threaded adapter without a knob or collar, relying on the receiving stand or accessory to clamp or thread onto it securely.
It uses standard 5/8-inch and 3/8-inch sizes, which are common across most brands of light stands and grip hardware, not just Manfrotto.
Many tripod heads, magic arms, and lighting brackets use 3/8-inch threads, while light stands typically present a 5/8-inch stud — the #184 connects the two.
