Blackmagic Design URSA Mini Pro Mount Screws PL

Genuine replacement mounting screws from Blackmagic Design for the PL mount on Blackmagic URSA Mini Pro cameras. According to the manufacturer’s instructions, the PL mount is secured to the camera body by five M2.5 × 22 mm screws with a 2 mm internal hex; these screws are specific to the PL mount and cannot be interchanged with other mounts.

The URSA Mini Pro mount is user-replaceable, so the screws must be loosened and tightened every time you switch between PL, EF, F, and B4 mounts—or when adding shims under the mount to adjust the back focal length. During such operations, it is easy to lose a screw.

The manufacturer recommends tightening the screws with a 2 mm Allen wrench—ideally a torque wrench set to 0.45 Nm—in the specified order using even pressure. Some screws are only accessible after slightly turning the PL locking ring. Over-tightening can damage both the thread and the mount.
