4900409 CAT Stud-Wheel

The 4471725 hex head bolt is a heavy-duty fastener used to securely join structural and mechanical parts on Caterpillar equipment. It provides strong clamp force to keep components tightly connected under vibration, load, and heavy use.

Here’s a general guide for proper installation:

1. Turn off the machine and ensure it is safely supported before starting work.
2. Clean the bolt hole and threads to remove dirt, rust, or debris.
3. Align the components to be fastened and insert the 4471725 bolt through the mating holes.
4. Thread the matching nut (if applicable) on by hand and then tighten with a wrench or socket to the torque specification listed in your service manual.
5. Double-check that the bolt is secure and components are aligned evenly.

The 4471725 hex head bolt is used in a variety of Caterpillar machines, such as excavators, loaders, and other heavy equipment, wherever a robust, threaded fastener is required. This part is compatible with many CAT models when this bolt size and specification are called out. Check your manual or reach out to Propel Parts for help verifying fitment.

Yes, the 4471725 bolt is engineered to meet or exceed OEM specifications for strength and durability, helping ensure reliable performance under heavy loads and vibration. Aftermarket versions are tested to fit and function like the original equipment bolt.

Bolts should be inspected during routine maintenance or whenever components are disassembled. Look for signs of thread wear, corrosion, stretching, or damage. Replace bolts that show wear or damage to maintain secure connections and prevent failures.

Typical indicators include:

1. Stripped or damaged threads
2. Visible corrosion or rust buildup
3. Deformation or bending of the bolt
4. Loosening despite proper torque

A quality hex head bolt ensures solid, secure fastening of critical components, helping prevent loosening, vibration-related issues, and premature wear. Using bolts that meet or exceed OEM specifications improves reliability, reduces maintenance costs, and contributes to the long-term durability of your equipment.
