Inserts can be obtained in either coiled or solid fabrications. Inserts are generally stainless steel, steel, brass, or aluminum. Inserts are also available with a locking feature that locks the installed part. The determination of whether to install coiled or solid inserts is dependent upon application. Mil-Spec applications are the most common applications.

SPRINGS: Compression, extension and torsion springs are available. These springs are generally music wire or stainless steel. They can be provided in various sizes and configurations.
