8S-9191 3/8″-16 x 4″ Hex Head Bolt
Cat® hex head bolt (line assembly, engine)
Description
Cat® fasteners are designed for specific applications based on size, strength, clamp load and past performance, information other manufacturers do not have. They are carefully selected to last until machine rebuild or end of life. Non-Cat hardware and fasteners may appear to fit your machine, but no one else knows your equipment the way we do. Hex head bolts/screws provide very strong driving performance. Cat fasteners are manufactured to precise specifications to be durable, reliable and efficient. Strength and quality – fasteners meet or exceed ISO, ASTM, ASME and SAE requirements. Cat bolts, nuts and washers are specially designed to work together as a system to maximize clamp load. Coatings meet the special requirements of different applications (RoHS compliant). Cat bolts form a matched system with matching hardened washers and nuts that consistently produces high clamping force. You can rely on Cat fasteners to help you build, maintain or repair, for most machine and shop applications around the world.
