• Replacement inserts are also offered for the whole range in different lengths

Let's make sense of the numbers:

Example:

M4 x 0.7 x 1.0D

M4: The Metric value of the required thread i.e. Metric 4mm
0.7: This is the pitch of the thread
1.0D: This is the installed length of the insert after installation

Determining the installed length:

M4 x 1.0D = 4mm deep
M4 x 1.5D = 6mm deep
M4 x 2.0D = 8mm deep

Thus, the depth (length) of the installed insert will be the metric diameter of the thread (in this case M4) multiplied by the “D” value
