Cat® Bolts, Nuts, Washers, Screws, Rivets, Springs & More
Many customers choose Cat® hardware for all
their needs because Cat hardware provides maximum strength, maximum selection
and maximum value.
Cat Hardware is Hard-Core
Caterpillar bolts meet or exceed SAE Grade 8 and ISO
10.9 strength specifications and are made from fine grain steel that produces
a more uniform microstructure for greater toughness and fracture resistance.
Bolt material hardness and thread designs provide high strength and resistance
to bolt threads stripping.
Cat bolt heads are higher than SAE Grade 8 standards for longer wear life and improved reusability.
Cat bolts and matching hardened washers and nuts form a matched system which produces consistently high clamp loads.
