Blackmagic Design URSA Mini Pro B4 Mount Screws

The Blackmagic Design Camera URSA Mini Pro Mnt Screws B4 (Pack of 10) is a dedicated hardware kit for securing the interchangeable B4 lens mount to the URSA Mini Pro chassis. These precision fasteners are essential for ensuring a light-tight, structurally sound connection between the camera's sensor turret and the broadcast lens mount.

Core Functionality

  • Mount Security: Specifically designed to withstand the torque and weight of heavy ENG and EFP broadcast lenses.

  • Precision Fit: The screws are manufactured to a specific length and thread pitch to prevent bottoming out in the camera body or damaging the internal mounting points.

  • Replacement/Spares: Since lens mounts are often swapped in the field, these small screws are easily dropped or lost. A 10-pack ensures that production is not halted due to missing hardware.

Technical Specifications

Feature Specification
Screw Type 2mm Hex (Allen) Head
Material High-tensile Stainless Steel
Compatibility URSA Mini Pro 4.6K, G1, G2, and 12K models
Quantity 10 Screws per pack
Manufacturer SKU BMUMCAPRO/MSCRB4

Installation Best Practices

When installing the B4 mount on an URSA Mini Pro:

  • Clean Surface: Ensure the mounting turret is free of dust or debris before placing the B4 mount.

  • Star Pattern Tightening: To ensure even pressure and proper flange focal distance, tighten the screws in a "star" or cross pattern rather than going in a circle.

  • Hand-Tighten First: Always start the threads by hand to avoid cross-threading the magnesium camera body.

  • Tooling: Use a high-quality 2mm hex driver. Avoid using worn-out keys as they can easily strip the shallow hex heads of these small screws.

Operational Insight

Unlike the standard EF or PL mount screws used on the URSA Mini, the B4 mount screws are specifically balanced for the internal optical block used in B4 correction. Because the B4 mount contains its own spherical aberration correction glass, any misalignment caused by loose or improper screws will result in significant image degradation (softness or chromatic aberration). Having a fresh set of screws ensures the mount remains perfectly parallel to the sensor.
