How to Install Brass Thread Inserts
Self-tapping brass thread inserts offer you the ability to easily install sturdy threads in thick plastics and wood. You need to select the proper brass insert for the material in which you are installing the insert, as the external threads are sized according to the holding power of the base material. Large external threads are designed to gouge deep into soft material, and small threads take advantage of the density of hardwoods and plastic. If you attempt to use the improper brass insert for the base material, the insert will either not hold or break during installation.
