SPECIFICATIONS FOR INSERT MATING HARDWARE
Group A and Group B should use an M8 forged steel shoulder-type lifting
eyebolt, which meets the requirements of DIN 580 or ASTM A489. They should
only be used in pairs, and in conjunction with the rear most pair of M8 inserts on
the same surface as a pull-back/aiming adjustment, using M8 eyebolts of a
similar specification. The length of the threaded shank on the eyebolts should
not exceed 0.709” (approx. 18 mm), so that it does not bottom out in the insert.
Thread pitch: 1.25 mm per thread.
The length of the threaded shank into the cabinet on the rear M8 eyebolt should not
exceed 0.709” (approx. 18 mm), so that it does not bottom out in the insert. Thread
pitch: 1.25 mm per thread.
Group C should use an M8, grade 8.8 or better, 1.25 mm per thread, metric bolt,
that does not penetrate the cabinet past the cabinet surface more than 0.709”
