These small inserts are hex screw insert made for Automotive industry. The material is 42CrMo,which has high hardness, so that the part can tolerate the pressure during the assembling.

we added the cold-forming before CNC machining, once dimensions are finished by Precise CNC lathes, like the screw, chamfer, etc, Machining center will be the final process to make the round slots in three places at one time.

Through the preparation of study,factory audit,samples making,we are starting the batch production for this fuel entrance seat,which is used for the high pressure fuel rail system in the automotive engine equipment.
