Thread Repair Kit 29pc M4 X 0.7 X 1.5d Internal Thread Carded
Restore stripped threads easily and permanently with Tork Craft thread repair
kits. Tork Craft application-specific thread repair kits make complex repairs simple
and are often a recommended solution by automakers.
Tork Craft inserts are available in thread repair kits and sets for permanently repairing tapped holes which have been stripped or damaged due to wear, corrosion, and over-torqing. Kits are offered in various thread series. All our kits have a quantity of inserts, the proper size drill, high-speed steel Tork Craft tap, and installation tool.
Available in M4, M5, M6, M8, M10 and M12. 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.
This kit includes 25 inserts for 6 mm deep/length threads.
