Assortments include various sizes of helical inserts and a tap, a drill bit, and an installation tool for each thread size.

Made of Nitronic 60 stainless steel, these inserts prevent the screw from binding or sticking without any coating or lubricant that could contaminate particle-free environments.

Eliminating the need for primer, these inserts are coated to resist corrosion when installed in different materials.

Made of nickel alloy, these inserts are more resistant to acids and salt water than stainless steel inserts.

A dry film keeps the screw from sticking or binding in these inserts during installation.

Without a prong to break off and retrieve, these inserts are often used where debris could cause damage.

A distorted thread grips the screw to resist loosening.

These kits have short-, normal-, and long-reach inserts, an installation tool, and a tap.
