2 1/4-8 X 9 12-POINT FLANGE SCREW A354-BD

12-point flange bolts are high-strength fasteners engineered to withstand the extreme demands of heavy-duty equipment in cement plants and mining operations. Featuring a 12-point head design for improved torque transfer and a built-in washer flange for even load distribution, these bolts deliver secure, vibration-resistant connections in harsh environments. Commonly used for mill liners, crushers, conveyors, kiln sections, and other critical machinery, they’re manufactured from premium alloy or stainless steel to handle abrasive materials, high temperatures, and intense mechanical stress.
