No need to counterbore or countersink the boss hole because the insert has guide pilot. Used on injection moulding for tightly fixing. Easy to install: From the moment that the insert has a valve conduit, there is no need to back-drill and counter-sink the hole. All nuts are made of brass, which has high hardness, no deformation, durable and reliable for long use.
