The cross-sectional shape of the standard internal thread used for fastening parts is a combination of two internal and external threads. Wire thread inserts are divided into two types: ordinary type and locking type, each with or without breaking grooves and with breaking grooves.
Designed and manufactured by thread insert to provide specific and unique benefits to high-temperature, high-performance spark plug applications.
