The Hollyland Screw Fitting for Mars 300 Pro is an official OEM expansion accessory designed to provide an ultra-secure, anti-twist mounting profile for the Mars 300 Pro transmitter and receiver units.
Standard single-screw cold shoe adapters often slip or pivot when your camera rig shifts quickly. This specialized mounting expansion plate screws directly into the chassis of the Mars 300 Pro to convert its base into a completely rigid mount that stays locked in orientation.
Core Design & Rigging Features
-
Dual-Screw Chassis Anchor: The plate features two integrated micro-screws that line up perfectly with the native alignment threads on the side or bottom of the Mars 300 Pro housing. By securing the transmitter at two points simultaneously, it completely stops the unit from twisting loose under camera movement.
-
Central Multi-Thread Integration: Once bolted onto the Mars 300 Pro chassis, the raised center portion provides a clean, reinforced $1/4"-20$ female threaded hole. This allows you to attach any standard articulating friction arm, monitor mount, or light stand stud natively.
-
Compact, Low-Profile Footprint: The plate is engineered with form-fitting chamfered edges that match the aesthetics of the Mars series. Its slim profile ensures that it doesn't add bulk or block access to the NP-F battery plate, HDMI ports, or the side OLED status display screen.
-
All-Metal Durability: Machined out of a single piece of high-strength alloy, this plate protects the composite casing of your wireless node from thread stripping caused by overtightening heavy-duty rigging accessories.

On-Set Installation Checklist: When mounting this plate to your Mars 300 Pro, tighten the two outer chassis screws evenly using a small flathead screwdriver or coin before screwing in your primary 1/4"-20 friction arm. Overtightening one side first can cause the plate to sit unevenly, which puts unnecessary stress on the wireless unit's internal threads.
