2.62 mm cross-section, static radial groove in a piston-style sample ring

2.62 mm cross-section, static radial groove in a piston-style sample ring: depth 2 mm, width 3.6 mm, bottom radius 0.3 mm. Ring Ø 50 mm, hole Ø 30 mm, 4 mm lands (sample layout). No clearance is printed, so the ring is drawn at the 50 mm bore with the groove cut from it.

Exact dimensions. True size, no printing tolerance added. Threads are plain cylinders at the major diameter.
