excavator track bolts supplier China
XZ Fastener supplies excavator track bolts from China for track shoe assemblies, crawler undercarriage repair, construction machinery spare parts, mining equipment service kits and heavy equipment distributors. Track bolts work under repeated impact, mud, abrasive dust, side load and high tightening force, so buyers need stable material, correct head geometry, thread fit and matching nuts. Orders can be supplied according to drawings, samples or size lists, with material grade, coating, packing and inspection documents confirmed before production. Matched bolt and nut sets are available upon request.
Quick Specs
What Buyers Should Know Before Sourcing Excavator Track Bolts
Excavator track bolts are not selected like ordinary structural bolts. The bolt head, shank, thread length, nut fit and heat treatment need to match the track shoe and chain plate. In service, bolts may loosen or fail when the wrong length, thread pitch, hardness or tightening method is used.
Because undercarriage parts work with shock and vibration, purchasing teams should confirm the machine model, shoe thickness, bolt hole condition and nut style before ordering. XZ Fastener recommends reviewing fasteners for equipment exposed to shock and vibration when building a track bolt specification.

Material and Grade Explanation
Excavator track bolts normally require controlled strength, hardness and toughness. Higher strength alone does not solve every undercarriage problem; the bolt also needs proper seating, correct nut fit and suitable tightening practice. For heavy equipment and mining service, buyers should confirm whether the application needs impact resistance, fatigue performance, wear resistance or a specific hardness range.
When comparing grades, consider load path, safety factor and field replacement schedule. This load capacity and safety factor guide can help purchasing and engineering teams define a practical requirement before ordering track bolts.
Surface Finish Selection Guide
Track bolts are exposed to mud, water, dust, stones and handling abrasion. Plain or oil black finish is commonly used when bolts are protected by oil film or installed quickly. Black oxide, phosphate or zinc plating may be selected for controlled storage and moderate protection. Dacromet or Geomet coatings can be supplied when corrosion resistance is requested, while coating thickness and thread fit should be checked together.
For mixed repair kits, bolt, nut and washer finish should be specified as an assembly. Buyers can compare options in the surface finish selection guide.
Manufacturing and Quality Control
Production Control
XZ Fastener can supply excavator track bolts according to drawings, samples or confirmed technical requirements. Production may include material preparation, forming, machining, heat treatment, thread rolling, coating, sorting and packing. For non-standard head geometry, special shank dimensions or private-label service kits, buyers can use the custom fasteners service.
Inspection Points
Common inspection points include material grade, head dimensions, shank diameter, thread pitch, thread fit, hardness, tensile strength, coating condition, marking and packaging labels. For high-strength parts, heat treatment stability and thread quality are especially important. XZ Fastener’s fastener quality control process explains key checks from raw material to packing.

How to Get a Faster Quotation
For excavator track bolts, send a size list with diameter, total length, thread length, thread pitch, head diameter, head height, nut requirement, material grade, finish and quantity. If possible, include the excavator model, track shoe thickness, sample photos or drawings. This helps confirm whether a standard track bolt can be supplied or whether custom production is needed.
For bulk maintenance or distributor orders, include packaging quantity per carton, label language, pallet requirement, inspection reports and delivery batch plan. If tightening requirements are part of the project, this bolt torque and preload guide can help align technical details before purchasing.
Preguntas frecuentes
Can XZ Fastener supply excavator track bolts from China according to samples?
Yes. XZ Fastener can supply excavator track bolts from China according to samples, drawings or detailed size lists. Buyers should provide head dimensions, thread details, material grade, finish, quantity and matching nut requirement.
What information is needed to quote track shoe bolts?
Please send diameter, total length, thread length, thread pitch, head diameter, head height, grade, finish, quantity and packing method. Machine model and track shoe photos are helpful for confirmation.
Can track bolts and nuts be supplied as matched sets?
Yes. Track bolts and nuts can be supplied as matched sets according to order requirement. Packing can be arranged by size, model, kit quantity or customer label.
Which finish is suitable for excavator track bolts?
Plain, oil black, black oxide and phosphate finishes are common for many undercarriage applications. Zinc plated, Dacromet or Geomet options can be considered when storage or corrosion protection is required.
Are DIN or ISO hex bolts suitable for track shoe installation?
Standard hex bolts may be used for auxiliary parts, but track shoe positions usually require special head geometry and matching nuts. Buyers should confirm the seating surface and machine requirement before replacing track bolts with ordinary hex bolts.
