We are high quality aftermarket Komatsu Hex Bolt supplier.Komatsu Hex Bolt is a high-strength hexagonal fastener widely used on Komatsu excavators, dozers, loaders, motor graders for undercarriage, bucket, cutting edge, track, sprocket, guard plate and other assemblies. It covers many application scenarios including track bolts, sprocket segment bolts, master link bolts and plow bolts for cutting edges, which are high-demand replacement fasteners for Komatsu machine maintenance.
Our aftermarket Komatsu hex bolts replacement perfectly match Komatsu OEM part numbers. Our hex head dimension, shank diameter, thread pitch and overall length fully comply with original specs for direct replacement. Except standard hex head, we also supply reinforced thick hex head, flange hex bolt and short shank hex bolt.

Installation Tips:
1. Thoroughly clean dirt, rust and burrs on workpiece contact surfaces and bolt holes before installation for flat contact.
2. Hex bolt and matched nut strength class must be the same. Mixing different grades will cause premature fastener failure.
3. Tighten to torque values specified in Komatsu service manual. Insufficient torque leads to loosening; over-torque causes bolt stretch and fracture.
4. Regular inspection and torque recheck for machines working under heavy mining conditions.
5. Replace hex bolt and nut set together during overhaul or worn parts replacement. Used bolts under cyclic load have metal fatigue and higher breakage risk for reuse.
Welcome to contact us for more detailed Komatsu hex bolts information : we promise that every batch undergoes hardness testing, tensile strength and shear load tests. Depend on stable quality, reasonable price and reliable lead time , we win more and more global customers's recognize and long-term orders !
