Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized hardware kits within our hardware and fasteners catalog to support diverse heavy-duty equipment:
• Machine & Overhaul Kit Compatibility: Engineered for a broad range of Komatsu heavy-duty excavators, loaders, and bulldozers, our kits ensure exact thread counts, alloy grades, and component groupings for a 100% perfect match, lossless installation, and factory-grade overhaul retention.
• Complete Hardware & Fastener Kit Range: 1. Engine & Cylinder Head Overhaul Bolt Kits: Integrated with high-strength alloy cylinder head bolts, main bearing cap bolts, and flywheel bolts to ensure tensile strength under extreme temperatures and pressures; 2. Track Shoe & Undercarriage Hardware Kits: Containing Grade 10.9 and 12.9 high-strength bolts and specialized anti-loosening nuts required for a complete track shoe replacement on an excavator; 3. Bucket Cutting Edge & GET Fastener Kits: Pairing high-strength countersunk and flange bolts with high-hardness locking nuts to withstand severe impact conditions; 4. Pin Retaining, Circlip & Clamp Assortment Kits: Providing workshop essentials, including high-frequency loss cotter pins, retaining rings, O-rings, and line clamps.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu hardware kits 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 hardware kit 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 BOM Mapping: We maintain large-volume stock of hundreds of differing specifications of overhaul hardware kits for Komatsu mainstream machines across every system. Backed by barcode-enabled intelligent warehousing and Komatsu original parts catalog 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 waiting for scattered small parts.
• Organized Compartments and Crated Protection: We implement specialized industrial packaging standards for hardware kits featuring diverse small components, high density, and extreme total weights that are highly vulnerable to package rupture, bolt mixing, or moisture corrosion during transcontinental transport, utilizing high-strength multi-compartment engineering plastic sorting boxes featuring anti-confusion label indexing sealed tightly with vacuum moisture-proof plastic film, and backing these with high-load thickened heavy-duty export corrugated boxes or fumigated solid wood crates to completely isolate marine salt spray and prevent rust or component mixing during ocean or air transit.
• Consolidated Sourcing for Overhaul Projects: We support overseas clients by consolidating hardware kits alongside matching Komatsu engine overhaul sets, hydraulic pumps, or undercarriage components into precise bundled shipments, achieving a one-stop purchasing model that combines core major components with complete fastener sets to maximize container space utilization and significantly reduce 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 overhaul security assets.
• Application-Specific Durability Solutions: We address common field issues in extreme jobsite environments, such as high-vibration open-pit mines and heavy dozer operations where standard commercial bolts experience widespread loosening and detachment within three months after overhauls due to insufficient fatigue strength. We also provide professional engineering upgrades, including full upgrades to Grade 12.9 aviation and mining-grade high-strength alloy steel hardware kits treated with Dacromet anti-corrosion surface coatings.
• Troubleshooting and Maintenance Guidelines: We address common user concerns regarding cylinder head gas leaks caused by bolts failing to meet torque and cross-tightening sequences or track shoe shedding on Komatsu excavators after overhauls by providing professional diagnostic and maintenance guidance. This includes emphasizing strict adherence to torque-angle and thread anti-seize protocols requiring technicians to use torque wrenches and specialized anti-seize lubricants and prohibiting blind pneumatic wrench tightening, while also mandating a strict no-mix policy requiring mechanics to replace old stretched bolts with new high-strength ones to eliminate structural stress imbalances.
• Expert Technical Support and Safety Guidelines: We provide technical documentation covering bill of materials index charts and standard torque value comparison manuals for every Komatsu system overhaul hardware kit, assisting overseas technical personnel in achieving rapid identification and standardized installations.
