Property class of threaded bolt should be at least Q10.9. Sizes of thread larger than M 16, should use a property class of Q 12.9, or the max. static load must be reduced. For optical control of actual screw-in depth of the T-bolt, two grooves are cut into the housing circumference matching tmin and tmax. When laying out the actual screw-in depth of the threaded bolt, the necessary stroke must be considered i. e. the max. specified screw-in depth must be reduced by at least the amount of the stroke.

Application example:
MCA-T-clamping nut for adjustment of test bench sliding table
