Washers
Flat, Spring & Lock Washers Manufacturer, Wholesaler, Supplier & Exporter
Flat, Spring & Lock Washers manufacturer, wholesaler, supplier and exporter from India. Global Fasteners Exports is a trading and export company: our flat, spring & lock washers are made to DIN 125, ISO 7089, DIN 127, ISO 7980 standards by partner factories and supplied to importers, distributors and OEMs in 222+ countries from 10,000 pcs, or a half or full container, at competitive prices below the average wholesale price.
Washers distribute load, prevent surface damage, and add locking resistance to a bolted joint. Our partner factories manufacture flat washers, split lock (spring) washers, and Belleville disc springs to DIN and ISO standards in steel and stainless steel.
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.
Spring (split lock) washers have fallen out of favor in modern high-vibration engineering for a reason worth knowing: independent testing has repeatedly shown they contribute little genuine anti-loosening benefit under vibration compared to a properly torqued joint or a true prevailing-torque lock nut. They're still widely used and still useful for taking up minor thread-length variance, but buyers relying on them as a primary vibration-resistance strategy are often better served by a lock nut or thread-locking compound instead.
Minimum order and container quantity
Minimum order
10,000 pcs
or half / full container, as per your requirement
Half container (20ft)
1.5-2.5 million pcs
Full container (20ft)
3-5 million pcs
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.
The minimum order is 10,000 pcs, so you don't need a full container to order: half-container and smaller LCL orders are available as well. 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.

Real-World Use Cases
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.
Glossary of 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.
Quality Inspection We Perform
Dimensional inspection
Thread gauge, length, diameter, and head/drive geometry checked against the specified standard.
Material verification
Grade and material composition confirmed against the order specification, with mill test certificates on request.
Mechanical testing
Tensile strength, hardness, and proof-load testing on sample batches, particularly for structural and high-tensile grades.
Finish & coating check
Plating thickness, galvanizing coverage, or passivation quality inspected before packing.
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.
