Bolt clamp A bolt clamp is a mechanical fastening device used to securely hold or clamp components together, often in industrial, automotive, or construction applications. It typically consists of a bolt, nut, and a clamp body that, when tightened, applies pressure to hold the parts together firmly. These clamps are used for a variety of purposes, including: Securing pipes or hoses: Bolt clamps are commonly used to hold hoses onto fittings or pipes, especially in high-pressure systems or where a strong, secure fit is necessary. Holding parts together: In machinery or assembly work, bolt clamps are used to hold parts in place during operations such as welding, machining, or assembly. Adjustable clamping: The tension on a bolt clamp can be adjusted by tightening or loosening the bolt, providing flexibility in how much pressure is applied.
