Trisert(reg) coarse thread metal inserts meet the demand for holding power in thermoplastics and thermosetting plastics. A wider-spaced external thread reduces installation torque and provides a stronger hold. Three external flutes give full cutting action, while retaining chips, keeping thread area clean. The inserts are available in brass only. Applications include automotive ones.
