Packaged inserts only
Heli-Coil Inserts are packaged according to thread size for easy handling and
display. The inserts are contained in a sturdy, clear, plastic display box and
marked with part number and thread size. The length of the inserts in inch and
metric package is 1 1/2 times the diameter of the bolt. This provides sufficient
strength in most applications. Spark plug hole inserts are packaged in length
corresponding to the various spark plug reaches. Some shorter and longer
reaches are also available.
