PLOW BOLT & NUT SET (5/8" x 63MM) FOR CAT, KOMATSU, CASE TEETH - 6Y6335

Technical Specification and Compatibility

An essential G.E.T. mounting component – a complete, hardened plow bolt (carriage bolt) in a high-tensile grade. This set, consisting of a bolt and a matched hex nut, is designed for fastening bolt-on teeth (center or side) and side cutters on CAT, Komatsu, and Case machines. The bolt features a countersunk head with a square neck, ensuring a flush fit and preventing rotation during tightening for maximum clamping force.

Application in machines

Brand Type / Series / Model
CATERPILLAR (CAT) Various excavators, loaders, and backhoe loaders.
KOMATSU Various excavators, loaders, and backhoe loaders.
CASE Various excavators, loaders, and backhoe loaders.

The list above is for reference. Fitment is determined by matching the dimensions: 5/8" (15.9 mm) thread diameter and 63 mm overall length.

⚠️ Safety Warning

Never reuse old plow bolts and nuts. They are single-use items that stretch. Reusing them risks bolt failure and violent detachment of the tooth or edge during operation, which poses a fatal hazard.

Part's Role in the Machine and Failure Diagnostics

The plow bolt is a critical fastener that transfers immense shear and impact forces between the tooth and the cutting edge. Its failure leads to an immediate loss of the working attachment.

  • › Loosening of teeth (symptom of worn threads or stretched bolt).
  • › Visible corrosion or shearing of the bolt head, preventing proper torque.
  • › Bolt fracture (due to material fatigue, corrosion, or overload).

🔧 Expert's Guide: Key Installation Tips

  1. Always replace as a set: Plow bolts are designed for single use. They stretch once torqued. Always install new teeth with new bolts and nuts.
  2. Clean surfaces: Thoroughly clean the countersunk holes in the lip and tooth of all rust and dirt. Debris will prevent the bolt head from seating correctly.
  3. Correct installation: Ensure the square neck of the bolt seats properly in the square hole. This prevents the bolt from spinning while tightening the nut.
  4. Torque Wrench: Tighten the nut (never the bolt head) with a torque wrench to the specification for a 5/8" Grade 10.9/12.9 bolt.
  5. Re-torque after work: After the first 2-3 hours of operation, you must re-check and re-tighten all tooth bolts.

Frequently Asked Questions (FAQ)

1. What is a "plow bolt" (carriage bolt)?

It is a special type of bolt that has a countersunk (tapered) head and a square neck just below the head. This square neck locks into the hole in the tooth/lip, preventing the bolt from spinning while you tighten the nut.

2. Can I use a standard 10.9 hex bolt instead?

No. A standard bolt has a hex head that is not designed to transfer shear forces in a countersunk hole. Using a regular bolt will cause it to shear off quickly or break, resulting in tooth loss.

3. Why must I re-torque the bolts after a few hours?

During the first hours of work, the tooth and bolt will "seat" perfectly into the cutting edge under immense forces and vibration. This can cause the nut to become slightly loose. Re-tightening the bolts after this break-in period ensures full clamping force for the rest of the tooth's life.
