How to Specify Helicoil Type Wire Thread Inserts
A correct RFQ should define the insert and the installation system together. If the insert size, STI tap, drill size, insert length, and tool type do not match, the repair kit may fail even when the product name appears correct.

Aluminum Parts
Wire thread inserts are commonly used for stripped threads in aluminum housings, covers, fixtures, and machinery parts.
