Population, capital, currency, and languages from Wikidata (checked 2026-09-23); time zones from the IANA tz database. Duty and tax rates change and transit depends on carrier, routing, and port congestion, so figures marked indicative are confirmed against your product and destination port when we quote. Your customs broker should verify final landed cost.
A flat washer's job looks trivial — spread load, protect the surface — but the wrong washer under a high-tensile bolt genuinely reduces the joint's effective clamping capacity, because an undersized or overly soft washer can crush or dish under torque before the bolt reaches its intended preload. Structural and high-tensile applications specify hardened flat washers for exactly this reason.
Curitiba Shipping Notes
- • Containers for Curitiba discharge at Paranaguá, then move 1 day by road to Curitiba.
- • Main fastener-buying sectors in Curitiba: automotive & vehicle assembly, manufacturing & engineering, agriculture & farm machinery.
- • Every lot ships with mill test certificates (EN 10204 3.1), packing list and certificate of origin for customs in Brazil.
Why Flat, Spring & Lock Washers Are in Demand in Curitiba
- ▸Vehicle assembly, body-building and auto-parts suppliers in Curitiba buy flat, spring & lock washers in steady repeat volumes.
- ▸Factories and engineering workshops around Curitiba use flat, spring & lock washers on machinery, frames and maintenance stock.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 3-5 million pieces of flat or spring washers in common sizes (M10-M12). Exact quantity depends on size and thickness and is confirmed at quote time.
You don't need a full container to order. Hurain Engitech & Trade — the group Global Fasteners Exports operates under — regularly ships smaller, partial-container (LCL) orders of just a few pallets or boxes for buyers who don't yet need FCL volume, consolidated with other cargo to keep freight cost reasonable.
Where Curitiba Buyers Use Flat, Spring & Lock Washers
General bolted joint protection
Distributing load and protecting the clamped surface from bolt-head or nut damage.
Preload retention under thermal cycling
Belleville (disc spring) washers maintaining clamp force as a joint heats and cools repeatedly.
Electrical earthing continuity
Toothed lock washers cutting through surface coatings to maintain a reliable earth connection.
Common Mistakes Buyers Make
Using a standard washer under a high-tensile bolt
A soft or thin washer can dish or crush before the bolt reaches its intended preload — use a hardened washer for structural and high-tensile joints.
Relying on spring washers alone for vibration resistance
Testing shows limited genuine anti-loosening benefit versus a proper lock nut or thread-locking compound.
Ignoring galvanic compatibility
A stainless washer under a plain steel bolt (or vice versa) in a wet environment can accelerate corrosion of the less noble metal.
Key Terms
- Belleville washer
- A conical disc spring washer (DIN 6796) that maintains clamping preload as a joint's grip length changes under thermal or mechanical cycling.
- Hardened flat washer
- A washer heat-treated to resist crushing under the preload of a high-tensile bolt.
- Galvanic corrosion
- Accelerated corrosion that occurs when dissimilar metals are in contact in the presence of moisture — relevant when mixing washer and fastener materials.
How Ordering Works
- 1
Send your requirement
Product, grade/standard, quantity, and your preferred Incoterm (FOB/CIF/CFR).
- 2
Receive a quote
We confirm price, lead time, and MOQ based on ready stock or manufacturing time.
- 3
Sample & confirm (optional)
For new buyers, we can arrange samples before the full order is confirmed.
- 4
Production, QC & shipping
Manufacturing or sourcing, batch inspection, export documentation, and container loading.
HS Code & Customs Classification
Most fasteners fall under HS Chapter 73 (articles of iron or steel) or Chapter 74/76 for brass and aluminum items — the exact 8-10 digit subheading depends on the specific product and material. We include the HS code on the commercial invoice; confirm the applicable import duty with your customs broker, since rates vary by country and trade agreement.
Packaging & Export Labeling
Export packing is chosen to survive ocean freight and container loading without corrosion or damage: corrosion-protected paper or oil coating where needed, then cartons, drums, or bulk bags, palletized or crated for the container. We can match specific labeling, barcoding, or carton-marking requirements for OEM and repeat buyers.
