Briefly Talk About Thread Insert Structure

    Wire thread insert, made of diamond-shaped stainless steel with high precision and high hardness, looks like spring, internal and external thread shares same core. Its external thread is screwed into matched thread groove and its internal thread will form standard internal thread that can properly connect with fastener.From perspective of its profile, the coil is a combination of internal and external screw thread. Wire thread insert includes free running and self locking thread inserts, both of which have two types--with notch or no notch.

    Self locking thread insert has one or more locking coils on the basis of free running thread insert. The elasticity of locking coil has braking effects on bolt.The self locking insert possesses all advantages the free running type has. The insert doesn't have negative effect on bolt installation. It only increases proper torque during installation.
