Description for part number 8T-4123

Description:
Hardened washers, such as part # 8T-4123, are recommended for use in critical joints to provide a controlled assembly surface and to lower contact stress generated by the fastener to a level the abutment material can support.

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:
• Hardened steel
• Coating: Zinc Flake
• Inner Diameter: 22 mm (0.87 in)
• Outer Diameter: 35 mm (1.38 in)
• Thickness: 3.5 mm (0.14 in)
• Fits M10 or 3/8 inch bolts

Application:
Cat bolts and the matching hardened 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.
