Thinwall Threaded Inserts

Manufactured to MIL-45932-1

Acme Swage-Sert thinwall threaded inserts are used to repair stripped, damaged or worn out threads. They are employed in original equipment to strengthen threads and extend thread life in soft base materials like aluminum or magnesium.

Swage-Sert inserts are also ideal when a lighter weight assembly is required.

Thinwall Design Permits Close Spacing

Swage-Sert inserts have a special thinwall design that allows them to be used with minimum boss requirements to help reduce weight and increase strength.

Swage-Sert inserts can be placed closer together than Acme’s traditional threaded inserts. They are locked securely into parent material by swaging the upper end of the insert into the wall of the parent material.

Lightweight, high strength Swage-Sert inserts have a solid, one-piece design that provides superior pull-out strength and torque-out capabilities.
