Welcome To Learn About Our Company
Quanzhou Hesen Machinery Industry Co., Ltd, located in Fujian Province, China. We have more than 30 years of experience as a manufacturer founded in 1990. We are a factory specialised in high-strength bolts and nuts, bucket teeth, pin & bush, excavator and bulldozer undercarriage parts. We also maintain a warehouse to store parts and provide rapid delivery for our customers worldwide — including major clients across the United Kingdom. It is a company which combines professional design, development, production and sales. Our products have earned strong market recognition both domestically and internationally.
View MoreThe United Kingdom is one of Europe's most active markets for heavy construction machinery and earthmoving equipment. Track roller bolts and undercarriage components play a critical role in keeping Britain's infrastructure moving — from HS2 railway construction to Scottish highland wind farm development.
The UK construction industry is valued at over £180 billion annually. Major infrastructure programmes such as HS2, the Thames Tideway Tunnel, and Crossrail have driven unprecedented demand for heavy excavators and track-driven machinery — directly increasing the consumption of track roller bolts, sprocket bolts and undercarriage fastening components.
UK plant hire companies and civil contractors operate to strict maintenance schedules. Quality-certified, OEM-compatible track roller bolts with verifiable tensile strength (Grade 10.9 / Grade 12.9) are the norm. Procurement managers in firms such as Speedy Hire, Lavendon Group, and Sunbelt Rentals prioritise suppliers with documented quality systems, including ISO 9001 compliance.
Post-Brexit, UK machinery parts buyers have increasingly turned to direct-from-factory procurement from established Chinese manufacturers. Competitive FOB pricing, faster production lead times, and full container load (FCL) shipping from major Chinese ports to Felixstowe and Southampton have made Chinese-manufactured track roller bolts and undercarriage parts a go-to choice for cost-conscious UK buyers.
Track roller bolts and associated undercarriage hardware serve a wide spectrum of industries throughout England, Scotland, Wales and Northern Ireland. Here are the primary application environments driving UK demand.
Major rail projects including HS2 Phase One between London and Birmingham require vast fleets of Komatsu, Hitachi, and Caterpillar excavators working around the clock. Track roller bolts for these machines must withstand extreme torque loads in clay-rich terrain. Our M20×57 and M20×2.5×90 track bolt specifications are fully compatible with the most common excavator models deployed on UK rail sites.
The quarrying industry is a cornerstone of the UK's construction materials supply chain. Sites in the Yorkshire Dales, Welsh valleys and Scottish Highlands run continuous crushing and extraction operations. Bulldozers such as the D8N — requiring 5P7665 segment bolts — are workhorses in these environments, demanding replacement fasteners with high fatigue resistance and superior thread tolerance.
With the UK targeting 50GW of offshore wind capacity by 2030, wind farm construction activity across coastal and highland regions of Scotland, East Anglia, and South Wales has surged. Track-equipped machines used for foundations and cable trenching face extreme weather and soft ground, placing high demands on undercarriage bolt integrity and corrosion resistance.
Housing shortfalls across Greater London and the Midlands have created sustained demand for compact excavators and wheeled loaders on brownfield remediation and new-build sites. Wheel stud bolts (1V3323, 6B6682) for Caterpillar wheel loaders are among the most frequently requested replacement components by plant engineers servicing these dense urban worksite fleets.
UK port expansion projects and dredging operations use heavy-duty crawler cranes and specialised track-based material handlers. The corrosive saltwater environment demands undercarriage bolts with high-grade steel compositions and anti-corrosion surface treatments — a key area where our factory's precision heat-treatment process delivers superior longevity.
The UK's circular economy agenda has accelerated selective demolition using hydraulic excavators fitted with specialist attachments. Companies operating across London, Manchester and Birmingham's urban cores replace track bolts, top rollers and carrier rollers at high frequency due to the stop-start, vibration-intensive nature of demolition work — making reliable, fast-delivery supply partnerships essential.
The UK undercarriage parts and fastener market is evolving rapidly. Understanding these trends helps buyers and suppliers align procurement strategies with long-term operational needs.
UK contractors are beginning to adopt electric and hybrid excavators, reducing emissions on urban sites. While the drivetrain changes, undercarriage hardware — track roller bolts, sprockets, and idlers — remains fundamentally unchanged, sustaining demand for quality fastener supply throughout the transition period.
UK plant managers are implementing telematics-driven maintenance systems (e.g., Komatsu KOMTRAX, Cat Product Link) that predict undercarriage wear intervals precisely. This is driving more planned, batch procurement of track roller bolts and undercarriage components rather than reactive, emergency purchasing.
Post-Brexit supply chain restructuring has made UK buyers more willing to engage directly with ISO-certified Chinese manufacturers. Eliminating European intermediary distributors can reduce component costs by 25–40%, making direct sourcing from factories such as Hesen increasingly attractive for UK depots and independent dealers.
As UK contractors face greater productivity pressure and tighter equipment downtime budgets, the appetite for lowest-cost, unbranded bolts is declining. Buyers increasingly specify Grade 10.9 and 12.9 high-tensile track roller bolts with full material traceability — a standard that Hesen has met for over three decades of international supply.
Environmental procurement policies within major UK contractors and government infrastructure projects are beginning to require suppliers to demonstrate carbon footprint reduction measures. Hesen's modern factory infrastructure, energy-efficient heat treatment furnaces and streamlined logistics processes position the company well for future green-certified procurement frameworks.
Fleet diversity across UK plant hire companies — mixing Komatsu, Caterpillar, Hitachi, Doosan, and Volvo machines — is driving demand for OEM cross-reference compatible parts. Manufacturers able to supply a unified catalogue covering multiple machine brands from a single source warehouse are winning UK supplier agreements at scale.
With over 30 years of manufacturing expertise and a dedicated export team serving the United Kingdom, Hesen delivers quality, consistency and value that UK plant professionals can rely on.
Eliminate intermediary markups. Hesen ships directly from our Fujian production base to UK ports (Felixstowe, Southampton, Tilbury), ensuring UK buyers receive the most competitive FOB and CIF pricing on track roller bolts, segment bolts, sprocket bolts and full undercarriage sets.
Every track roller bolt produced at Hesen undergoes multi-stage quality control including hardness testing, dimensional inspection and surface treatment verification. Tensile strength, yield strength and proof load values are documented per batch — fully meeting ISO 898-1 international fastener standards demanded by UK procurement specifications.
Our 200,000+ m² facility maintains extensive finished goods inventory. Standard orders for M20×57 track bolts, M20×2.5×90 roller bolts, and 5P7665 segment bolts can be consolidated and shipped within 7–15 working days from order confirmation — significantly faster than many UK-based re-distributors of equivalent specifications.
