Flush press-fit inserts install into pilot holes in a mounting surface and create a female-threaded mounting point. They feature relief grooves along their length and knurling on their outer surface. These grooves let the insert contract slightly during installation, allowing them to press-fit into place. Once installed, a male-threaded fastener is screwed into the insert, expanding it and causing the knurling to engage with the mounting surface and lock it into place.

Flanged press-fit inserts install into holes in the mounting surface and provide a female-threaded mounting point. They feature relief grooves that contract during installation and an integrated flange that controls the insertion depth, ensuring their threads are positioned correctly.

Reverse slot press-fit inserts install into pilot holes in a mounting surface from the blind side. They provide mounting points for reverse-thread fasteners that are highly resistant to pull-out.

Finned press-fit inserts, sometimes called finserts, install into holes in the mounting surface and provide a female-threaded mounting point. They feature relief grooves that contract during installation and fins that embed into the mounting surface, increasing their holding power. They are commonly used in soft materials to reduce the chance of damage or a pull-out.
