Hardware And Fasteners/Bolts(Common Parts)

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized bolts within our hardware and fasteners catalog to support diverse heavy-duty equipment:
• Machine & Fastener Application Compatibility: Engineered for a broad range of Komatsu heavy-duty excavators, loaders, and bulldozers, our parts ensure exact thread dimensions, alloy grades, and head profiles for a 100% perfect match, lossless alignment, and factory-grade joint retention.
• Complete Heavy-Duty Fastener Range: 1. Undercarriage Track & Roller Bolts: Engineered with high toughness and fatigue resistance to endure high-frequency ground impacts and tensile shear forces in track systems; 2. Bucket Edge & GET Plow Bolts: Pairing Grade 12.9 high-strength countersunk and flange bolts with high-hardness nuts to securely anchor KVX or Hensley cutting edge systems; 3. Engine & Hydraulic Structural Bolts: Precision alloy fasteners manufactured to meet high-temperature, high-pressure, and high-vibration requirements across cylinder heads, flywheel housings, and main pump flanges.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu fasteners alongside rigorous bench-tested aftermarket parts, delivering exceptional operational reliability and extended service lifespan at a cost-effective procurement point for global clients.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global bolt procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international equipment owners and repair facilities.
• Massive Inventory and Cross-Reference: We maintain large-volume stock of hundreds of differing specifications of high-strength bolts for Komatsu mainstream heavy-duty machines across every assembly zone. Backed by barcode-enabled intelligent warehousing and Komatsu parts databases, we guarantee precise matching and immediate dispatch upon order confirmation to fulfill routine maintenance and rapid replacement needs for overseas fleet workshops and minimize equipment downtime caused by a single broken fastener.
• Anti-Rust Sealing and Crated Bulk Packaging: We implement specialized industrial packaging standards for bolt products featuring compact unit dimensions, high density, and large quantities that are highly vulnerable to moisture corrosion, thread stripping, or scattering during transcontinental transport, utilizing environmentally friendly long-lasting Dacromet or heavy anti-rust oil surface sealing combined with high-strength thickened plastic bags vacuum-sealed into categorized grid compartments, and backing these with high-strength independent corrugated boxes or heavy-duty export wooden crates to completely isolate marine salt spray and prevent rust or package rupture during ocean or air transit.
• Consolidated Sourcing for Hardware Kits: We support overseas clients by consolidating high-strength bolts alongside matching large components, such as track shoes, cutting edges, and filters, into precise bundled full-set hardware maintenance kits, achieving a one-stop purchasing model that maximizes container space utilization and significantly reduces comprehensive logistics costs for overseas workshops.

Engineering Solutions & Technical Support
Our technical framework focuses on resolving field-level operational challenges to eliminate equipment downtime, moving beyond simple parts distribution to deliver comprehensive engineering and service capabilities for joint security assets.
• Application-Specific Durability Solutions: We address common field issues in extreme jobsite environments, such as heavy quarries and high-vibration dozer operations where standard factory bolts experience fatigue fracture and track shoe loosening within three months under continuous alternating impacts. We also provide professional engineering upgrades, including Grade 12.9 ultra-high tensile strength and anti-fwd-wear surface-treated heavy-duty reinforced bolts.
• Troubleshooting and Maintenance Guidelines: We address common user concerns regarding Komatsu undercarriage rattling noises, excessive bucket cutting edge looseness, or frequent bolt snapping during disassembly by providing professional diagnostic and maintenance guidance. This includes emphasizing the strict execution of torque-angle and thread lubrication protocols requiring technicians to use torque or hydraulic wrenches to cross-tighten bolts in staged sequences and applying special anti-seize compounds to threads, strictly prohibiting dry tightening or over-torque stretching, while also mandating the complete non-reuse of fatigued high-strength bolts under high shear loads, such as track shoe and cutting edge fasteners, to prevent catastrophic joint failures.
• Expert Technical Support and Safety Guidelines: We provide technical documentation covering precise torque value tables and tightening sequence diagrams for key structural components including track pins, swing circles, and engine flywheels, assisting overseas technical personnel in maintaining standardized installations.
