JMP threading equipment

JMP offers this threading equipment. When a bolt is overtightened or started at an angle, it often strips the thread in the aluminium of the engine or frame, and it no longer holds.

Why repair rather than replace?

The benefits:

• A crankcase, cylinder or frame saved for the price of an insert instead of a new part.
• A steel insert, stronger than aluminium, at the original bolt size: ideal for bolts that are removed often, such as the drain plug.
• Taps and dies in treated steel: they cut cleanly and restore a clean thread without tearing it.

Why choose JMP?

JMP stands for Johannes Matthies Products, the brand of the Matthies wholesale company, founded in Hamburg more than 80 years ago, which supplies tools, workshop equipment, wear parts and spares to the vehicle trade. Sold notably by the German specialist Louis, the JMP range covers many motorcycles as an alternative to original parts.

When should you replace this tool?

A tap or die that is dull, chipped or unusually stiff risks breaking in the part: replace it, and restock inserts as soon as the box runs low.
