Description for part number 9X-8979

Description:
Dowel pins are headless straight pins with a closely controlled diameter used to transmit load or to position adjacent parts by being press fitted in one or both parts. Cat fastener & hardware 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:
• Hardened steel pin
• Pin diameter: 6 mm (0.24 in)
• Length: 18 (0.71 in)
• End Type 1: Chamfer-Crown
• End Type 2: Crown

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.
