About usLeading and experienced manufacturer in the fastener industry
CLT Fasteners is located in Jiaxing City, Nearby Shanghai, which belongs to Chenglong Technology(Jiaxing) Co., Ltd., covering a construction area of over 20,000 square meters. With an annual production capacity of over 20,000 tons, it specializes in manufacturing various general fasteners, auto parts, and fasteners for railways and power. We’re a leading manufacturer in the fastener industry.
Our strengthThe company's R&D department has 15 professional engineers and invests 4% of its annual revenue in process improvement and product development. We not only meet existing standards but also actively participate in our clients' early design phases, providing customized solutions.
Specializing in various general-purpose fasteners, automotive parts, and railway and power fasteners.
Not every project needs a fastener engineered for a specific stress condition — most assembly work calls for reliable, standards-compliant parts that are readily available and easy to source in volume. The General Fastener Series is built for exactly that: broad coverage across common nut, bolt, and screw types, so you can consolidate routine fastener sourcing with a single supplier instead of managing it across several.
For applications with a specific vibration, load, or environmental requirement, see our Automotive Parts Series or Special Parts for Railway Power.

Framing, panel, and enclosure assembly where standard hardware covers most of the bill of materials.
Replacement fasteners for repair and upkeep work, where consistent stock availability matters more than a specialized spec.
General structural and fixture assembly on-site or in the workshop, using standard-grade hardware.
Buyers consolidating several fastener types into one order to simplify procurement and reduce supplier count.

Automotive assembly runs at high volume and high frequency, on production lines where a single inconsistent batch can stall the line. That makes batch-to-batch consistency as critical as the fastener's own strength rating — a supplier who can't hold tight tolerances at scale becomes a line-stoppage risk, not just a parts risk.
Fasteners also have to hold under continuous vibration over the vehicle's service life. A standard hex nut relies on thread friction alone to stay in place — under sustained vibration, that friction gradually breaks down and the nut can back off. This series is built around locking mechanisms and specialty nut types that address that failure mode directly, rather than standard hex nuts alone.
■ Nylon Lock Nuts Carbon Steel / Brass
A nylon insert creates friction against the bolt threads, resisting loosening under vibration without damaging the threads — the standard choice for most vibration-prone joints.
■ Metal Lock Nuts Carbon Steel
An all-metal locking mechanism gives the same vibration resistance as a nylon lock nut, but withstands higher temperatures — used near engine or exhaust-adjacent mounting points where a nylon insert would degrade.
■ Slotted Nuts Carbon Steel
Secured with a cotter pin through slots in the nut and a hole in the bolt, giving a positive mechanical lock for critical connections where friction-based locking alone isn't considered sufficient.
■ Square Nuts Carbon Steel
A larger bearing surface and flat sides resist rotation, useful in tight assembly spaces where a wrench flat can't be held on the nut side.
For full specifications on each product, see our Nuts and Bolts pages in the Product Center.
High-vibration mounting points where sustained road shock makes loosening resistance a baseline requirement, not an upgrade.
Fixtures near heat sources, where an all-metal locking mechanism holds up where nylon inserts can't.
Panel and trim fastening at high line speed, where consistent torque and batch uniformity keep automated assembly on schedule.
Tight assembly points where a standard wrench flat can't be held, calling for a nut profile that resists rotation on its own.

Fasteners used in railway power infrastructure carry structural and safety-critical loads, often in outdoor environments with long service intervals between inspections. A connection that loosens or fails between maintenance cycles isn't just a part failure — it's a service disruption or safety incident, which is why load capacity and long-term reliability take priority over standard specifications here.
This series is built around heavy-duty hex components sized for that kind of load-bearing, long-term application, rather than the general-purpose hardware used in routine assembly work.
■ Hex Heavy Nuts Carbon Steel
A thicker profile than a standard hex nut, giving greater thread engagement and load capacity for heavy structural connections that need to stay secure over years of service.
■ Hex Heavy Head Bolts Carbon Steel
A larger head bearing surface for higher torque application and load distribution, matched to the heavy nut profile for a connection sized to carry sustained structural load.
For full specifications on each product, see our Nuts and Bolts pages in the Product Center.
Catenary and support structures that carry sustained mechanical tension and need connections rated for long-term structural load.
Structural framing exposed to outdoor conditions year-round, where fastener reliability directly affects structural safety margins.
Fixed equipment enclosures and brackets that need to stay secure between scheduled maintenance windows.
Heavy structural connections around power distribution equipment, where load capacity is a baseline safety requirement.
