What Are Cast Iron Hand Knob with Steel Clamping Pad and Serrated Gripper?

These Cast Iron Grippers are a rugged and dependable clamping solution designed for industrial, workshop and mechanical applications where secure tightening and high traction engagement are required. The hand knob is made from cast iron with a black finish, providing a strong, durable grip essential for frequent use and harsh environments. Cast iron knobs are designed for robust performance and ergonomic handling, making them ideal for tightening and adjustment tasks across machinery, fixtures and other equipment. This assembly is paired with a steel clamping pad featuring a serrated gripper face. The threaded pad body is made from hardened alloy steel with a black oxide finish, offering excellent wear resistance and long service life. The pad incorporates a high-hardness steel ball with a serrated contact surface, which bites into the workpiece to deliver enhanced grip and resistance to slippage, especially under load. A Viton O-ring holds the ball and helps provide smooth, controlled movement while sealing out contaminants.
