Insert(Thread Dia. (After inserted), Unified:#4-40)

These products are used for reinforcing female threads. These can be used with damaged female threads or soft materials to enable screws/bolts to be tightened.
In general, coil inserts that have been machined into a coil shape are very common, but we also have a wide lineup that includes "self-tapping inserts", "inserts for resin", "insert nuts", "locking inserts", etc., enabling use to suit various environments or materials.
MISUMI enables spec searches and ordering quantities from just 1 piece. Tools are also sold in addition to the inserts themselves.
