* Property class of threaded bolt up to M 24 minimum Q 10.9; from M 30 Q 8.8 (further thread sizes i. e. inches on request)
standard thread tolerance 6G

Note:
For optical control of actual screw-in depth of the T-bolt, two grooves have been provided on 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 at least by the amount of the stroke.

max. allowed temperature range: -30°C up to +200°C (optional up to 400°C)

The nominal clamping force can be influenced considerably by various parameters, such as thread length, surface quality, or thread greasing.

Ordering example:
clamping nut (1*) MCA 100 – (2*) M 24
incl. T-bolt (1*) MCA 150 – (2*) M 30 – (3*) 100 – (4*) 36

(1*) series and size
(2*) thread size (T-bolt screw thread according to DIN 787)
(3*) clamping height (H = 100 mm)
(4*) width of T-bolt (A = 36 mm)
