clinching

Clinching refers to the act of securing or fastening by tightly gripping or deforming, and is used in a variety of fields such as sports, engineering, and business. It can denote the moment when a round or contest is decided, or a technique to pin an opponent.

In combat sports, clinching is a close-range grappling position where fighters wrap their arms around the opponent to gain control, neutralize strikes, or set up takedowns. Common methods include underhooks and body locks. It is regulated by rules to prevent stalling or dangerous holds; referees may break the clinch or penalize illegal grips, with an emphasis on safe technique and control.

In manufacturing and metalworking, clinching is a fastening method that forms a joint by deforming one or both parts so they grip each other. It is used to attach nuts or fasteners to thin sheet metal without welding or threading, often via a clinching tool or press. Clinch joints are found in consumer electronics, automotive panels, and appliances.

In business and diplomacy, to clinch means to secure a deal or victory, bringing negotiations to a final agreement or a decisive result. The term implies a successful conclusion, often after deliberation or compromise. Clinical or practical considerations in negotiation include timing, concessions, and clear final terms to ensure a durable agreement.
