Key Notes:
Part Number: 2J3506
Weight: 0.2 lbs (0.09 kg)
Size: 3/4"
Material: Hardened steel — designed for ground engaging applications
Application: Cutting edge mounting nut — secures dozer blade cutting edges and end bits to the blade moldboard in conjunction with compatible 3/4" cutting edge bolts
Compatible Bolts: 5J4773 (3/4" x 2-1/2"), 4F0138 (3/4" x 3") — sold separately
Note: Verify your cutting edge hardware uses 3/4" diameter mounting bolts before ordering — this nut is designed for 3/4" bolt systems only
Common Use Case or Symptoms: Use when replacing dozer blade cutting edges or end bits, when existing nuts are stripped, seized, or missing — proper cutting edge hardware torque is critical to maintaining secure blade attachment and preventing cutting edge separation during dozing operations.
