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.
Features
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 specifically designed to work together as a system to maximize clamping force.
- Coating meets the special requirements of different applications (RoHS compliant).
- Recommended by engineers familiar with the product.
Applications
Cat® bolts form a high-performance system with matching hardened washers and nuts that produces consistently high clamping force. Cat® fasteners help you build, maintain or repair for most machine and shop applications worldwide, and they can be trusted.
