Thorlabs' Mini-Series breadboards, designed for setups where space is a premium, offer increased tapped hole density with 1/2" (12.5 mm) spacing. These high-density breadboards are offered with either 4-40 (M3) tapped holes or both 8-32 (M4) and 1/4"-20 (M6) tapped holes.
Our Mini-Series line consists of components that are compatible with 4-40 (M3) or 8-32 (M4) threads. The 4-40 (M3) taps in the MS12B(/M) breadboard make it compatible with smaller 4-40 (M3) Mini-Series components, such as our Ø6 mm posts. Our other breadboards are compatible with 8-32 (M4) Mini-Series components, such as our Ø12 mm pedestal posts and MSL post holders, and also include 1/4"-20 (M6) taps for integrating larger optomechanical components, such as our Ø1/2”, Ø1”, and Ø1.5” post assemblies.
Each breadboard features two, four, or five counterbored mounting holes, depending on the size of the board, enabling these breadboards to be mounted onto our standard breadboards, mounting feet, or post assemblies. For breadboards that have a fifth counterbored hole, it is located at the center of the breadboard to reduce stress at the four corners and to increase system rigidity when mounted. Refer to the tables below for more specifications.
We also offer a selection of breadboards with 8-32 (M4) and 1/4"-20 (M6) mounting holes designed for use with Thorlabs' Customizable Electronics Enclosures or LCC7201B Birefringence Imaging System. These breadboards have counterbored mounting holes positioned to allow the breadboards to be mounted directly into the compatible system. The breadboards for the imaging systems also feature a Ø1.97" (Ø50.0 mm) central aperture aligned with the optical axis of the imaging system.

I am mounting components that use two M4 taps next to each other (in order to secure alignment). For this, a "pure M4 edition" of the "Breadboards with 8-32 (M4) and 1/4"-20 (M6) Taps" would offer greatly enhanced flexibility. That is, an edition where all M6 taps are replaced by M4 taps.
Best regards

The MSB1823(/M) and MSBU1823(/M) breadboards are designed to fit inside the EC2030A(R) or EC2030B(R) benchtop enclosures for custom electronics, and the MSBU3038(/M) breadboard is designed to fit inside the EC2U and EC3U 19" rack enclosures for custom electronics.The MSB1823(/M) and MSBU1823(/M) have a thickness of 0.28" (7.0 mm) while the MSBU3038(/M) has a thickness of 0.37" (9.5 mm). In addition, these breadboards have four M3 counterbored mounting holes for compatibility with the enclosure, rather than 1/4" (M6) counterbored holes.
