Overview
This insert family provides a durable internal thread in a material that cannot hold one on its own, either because the parent alloy is softer than the working screw or because the thread will be opened many times over the equipment life. The insert is installed into a prepared hole and becomes the load-bearing thread, so wear and repair happen at the insert rather than in the housing. This listing: thread M3–M20 available, standard Metric M thread, material 304 stainless steel, finish Plain.
Advantages
Pull-out strength scales with engaged length, so insert length — not thread diameter — is the parameter to increase when a joint pulls out under load.
The installed thread can be renewed or replaced without welding, so a single damaged hole does not condemn an entire casting.
Thread life is transferred from the parent material to a hardened or stainless insert, which is the difference between a housing that survives ten service cycles and one that is scrapped after three.
Applications
Die-cast and machined housings that must accept repeated assembly, repair of stripped threads, and joints where the parent alloy is softer than the mating screw.
State the parent material and the required pull-out load when ordering: hole size, insert length and locking method all follow from those two numbers, not from thread size alone.
