UNC/UNF Cutting Slot Self-tapping Insert are cylindrical metal bushings featuring internal and external threads. They are specifically engineered to create their own threads while being inserted into a pre-drilled hole. Self-Tapping Inserts with cutting slot offer durable, wear-resistant threading solutions for a broad spectrum of materials, ranging from robust high-strength steels to brittle plastics. By enabling the creation of their threads, Self-Tapping Inserts eliminate the need for pre-tapped holes.
