The maintenance of large diameter threads can be quite
complicated and rather costly. Due to their larger size
and weight, it is often difficult to work on the damaged
threads at a workbench or on a table. The repairs have
to be conducted on the spot. Furthermore, the larger
diameters require larger tools which require larger
clearance to complete the repair. Traditionally, one would
dismantle the entire part, bring it to the workshop and
rethread it there. Oftentimes this may not be feasible to
do by hand, subsequently requiring expensive power tools.
Alternatively, one could use a thread file and quite a bit
of elbow grease. Both of these methods are aggravatingly
arduous and time consuming.
Luckily, Nes has an easy and cost effective solution to the
problem of repairing large diameter threads. Our internal
and external thread repair tools slide into the thread and
adjust to its diameter and pitch automatically. A couple
rotations and boom, fixed with barely any effort! Nes
thread repair tools don’t only reduces the time and effort
put into the job, they also save you some serious money.
You no longer need to spend large quantities on taps, dies
or power tools as the Nes internal and external thread
repair tools can do it all with perfect results every time!
