    • Color Notes
      Bolts sizes M6 through M12 with the new Zinc Flake finish will be black. Bolts sizes M14 through M36 with the new Zinc Flake finish will be gray. Until stock of the current finish is depleted, you may receive either the current or new bolt color.

Cat® Bolts are engineered to exceed SAE Grade 8 standards and ISO 10.9 strength specifications for longer wear life and improved reusability.

Over 1,700 Bolt Types

We offer over 1,700 different bolt products with various grip lengths, thread sizes and finishes. The material hardness and thread designs of our bolts provide the high strength and resistance to bolt threads stripping your need for demanding applications. Many of our bolts have a Zinc Flake finish that provides improved corrosion resistance compared to a bolt with Zinc Plate coating.

Maintenance Tips for Cutting Edge Hardware

  1. Clean all surfaces of rust, paint, nicks, and burrs.
  2. Install bolts first in the center and work out toward the edge.
  3. Tighten all bolts to the specified torque (see chart below for specifications).
  4. Set bolt heads firmly into the edge countersink using a heavy hammer. Safety glasses MUST be worn when striking bolt heads.
  5. Tighten all bolts again to the specified torque.
