About This Part
Assembly support brackets are judged by how their holes line up when the screws go in. This bracket carries 25 h13 and 11 h13 controlled steps, an M3 6H thread plus two M2.5 6H threads, and multiple Ø4 H9 plain bores, with coaxiality at 0.03 across the aligned features and flatness 0.2 on the body.
R10 radii and 45 degree chamfers define the edges. The black anodize finish matches the instrument stack appearance and handles handling wear, with controlled bores protected through treatment.
Inspection runs dimension, geometric, and appearance checks with the coaxial pair and the H9 bores as criticals.
This part family supports the Optical / Semiconductor Parts industry. Read how KGL machines parts for that sector, then send your drawing for a quote.
Why Machine It at KGL
Five-Axis Fleet
100+ CNC machines including 11 five-axis centers run complex geometry in single setups, so tolerances do not stack up across refixturing.
Verified Accuracy
±0.005 mm standard on metals, plastics, and carbon fiber composite, verified on Hexagon and Zeiss CMMs (0.0015 mm accuracy).
Fast Prototypes
Engineering feedback with every quotation; prototype parts typically machined in 15 to 25 days.
One Supplier, End to End
Material sourcing, machining, heat treatment coordination, finishing, CMM inspection and export packaging under one roof.

Common Questions
What is H9 for on plain bores?
A clearance class that still locates: close enough to position the mating pin or bolt without press fit fuss, loose enough for assembly speed.
Why call out coaxiality on a bracket?
Because the bracket carries alignment between two assemblies. 0.03 coaxiality means the screws never have to bend a part to make it fit.
