Blackmagic Design Camera URSA Mini Pro MNT Screws PL

The Blackmagic Design Camera URSA Mini Pro MNT Screws PL is a dedicated set of replacement hardware used to secure the interchangeable PL (Positive Lock) lens mount to the camera body. These screws are essential for users who frequently swap between EF, PL, B4, or F mounts on their URSA Mini Pro or URSA Broadcast G2 cameras.

Kit Contents and Specifications

This spare part kit provides the specific high-tensile hardware required for a safe and level mount installation.

• Quantity: Typically comes in a set of 6 screws. While the PL mount only requires a specific number for installation, the extra screws serve as vital backups in case one is dropped or misplaced during a mount swap in the field.

• Drive Type: Designed for use with a 2.0mm Hex (Allen) wrench.

• Precision Threading: These screws are custom-milled to seat perfectly into the camera’s magnesium alloy chassis without cross-threading, ensuring the mount is flush against the sensor plane.

Compatibility

These screws are designed specifically for the Blackmagic interchangeable mount system:

• URSA Mini Pro Series: Compatible with the 4.6K, 4.6K G2, and 12K models.

• URSA Broadcast G2: Fits the revised chassis that supports the interchangeable mount system.

• Mount Type: Specifically for the PL Mount (Blackmagic SKU: BMUMCA/PROPLMNT).

Installation Best Practices

Because the lens mount supports the weight of heavy cinema glass, proper installation of these screws is critical for equipment safety and image quality.

• Star Pattern Tightening: To ensure the mount is perfectly level, tighten the screws in a "star" or cross-pattern (tightening opposite sides sequentially). This prevents the mount from tilting, which could cause one side of your image to be out of focus.

• Torque Warning: Do not overtighten. The screws should be firm to prevent vibration, but excessive force can strip the threads in the camera body or snap the screw head.

• Cleanliness: Always ensure the mounting surface and the screw threads are free of dust or metal shavings before installation to maintain a perfect flange focal distance.

Note: These screws are specifically for the PL mount. If you are using the EF or F mount, the screw lengths and head profiles may differ. Always verify you are using the "PL" designated screws when installing a PL mount to ensure proper clearance for cinema lenses.
