Description
Description
Description: Cat® fastener parts are designed for specific applications based on size, strength, clamp load, and past performance. This is information other manufacturers do not have. They are selected to last until rebuild or the life of the machine. While it may seem as though non-Cat hardware and fasteners are suitable for your machine, no other company knows your equipment like we do.
Attributes: •Cat Fasteners are manufactured to precise specifications and are built for durability, reliability, productivity •Strength & Quality – Fasteners meet or exceed ISO, ASTM, ASME & SAE requirements. •Cat bolts, nuts, and washers are designed to work together as a system for maximum clamping force. •Coatings that meet special requirements for different applications (RoHS compliant).
Applications: Cat bolts and the matching washers and nuts form a performance based system which produces consistently high clamp loads. You can trust Cat Fasteners to help you build it, maintain it, or fix it - for most machine and workshop applications throughout the world.
Warning:This product can expose you to chemicals including Lead and lead compounds, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
