Description
Cat® fastener parts 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.
These bolts are commonly used in engines and driveline. 12-point head bolts have high fatigue performance and fit designs that do not have enough clearance for hex head bolts.
Features
- Cat fasteners are manufactured to precise technical specifications for durability, reliable performance, and high efficiency
- 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 clamping force.
- Coatings meet the special requirements of different applications (RoHS compliant).
Applications
Cat bolts form a high-performance system with mating hardened washers and nuts to produce consistent, high clamping force. You can trust Cat fasteners to help you build, maintain or rebuild in most machine and shop applications worldwide.
