Grade 10.9 bolts are manufactured using medium carbon steel, medium carbon steel alloy and low carbon boron steel that has been quenched and tempered. Mainly used in automotive applications for bolting large and forged parts, metric 10.9 bolts exhibit high tensile strength and good wear resistance.

Here in astronomy we use these screws for attaching a finderscope shoe / bracket / base to a telescope where there is a M5 threaded hole on the focuser or elsewhere on the tube.

Size of thread: M5
Length of thread: 9mm
Steel quality: Grade 10.9
Although not shown on the below image, this screw is compatible with 2457000A Baader Standard Base and Primaluce Lab DX Deluxe Finderscope Shoe.
