If you are sourcing Elastic Spiral Spring Pins in China, you will find many suppliers using different names for the same product, including spiral spring pins, coiled spring pins, and rolled spring pins. The product uses a coiled metal strip rather than a solid body. This allows the pin to compress during installation and maintain radial force inside the hole. Standard-duty spiral spring pins are commonly associated with ISO 8750 and DIN 7343.
For B2B buyers, the supplier should be checked on more than price. Material, coil structure, diameter, length, hardness, surface finish, production tolerance, and order quantity all affect the final result. The following 10 Chinese manufacturers and suppliers are worth considering when sourcing spiral spring pins for machinery, automotive components, equipment, and general mechanical assemblies.

Anhui Pins Metal Products Co., Ltd. focuses on precision pins and metal fastening components for industrial applications. Its product range covers Dowel Pins, Slotted Spring Pins, Tooth Spring Pins, and different types of Coiled Spring Pins.
The company also supplies Elastic Spiral Spring Pins. The coiled structure gives the pin radial elasticity during installation. As the pin enters the hole, the coil compresses and produces outward force against the hole wall. This allows the pin to retain its position while accommodating small variations in the mating hole.
For an Elastic Spiral Spring Pins Manufacturer in China, production accuracy is important because the pin diameter and coil structure affect insertion force and retention. The required length, material, hardness, surface treatment, and dimensional tolerance can be defined according to the application.
The company also handles custom Elastic Spiral Spring Pins based on customer drawings, samples, or specified dimensions. This is useful for OEM projects where the required pin does not match a standard catalog size. Buyers can discuss material, diameter, length, finish, tolerance, packaging, and other production details before placing a bulk order.
Another advantage is the wider pin range. A buyer that needs Coiled Spring Pins, spring pins, and dowel pins for the same project can source several products through one manufacturer. This can reduce the number of suppliers involved in repeat purchasing.
For companies comparing a China Elastic Spiral Spring Pins factory, the focus on pin products is worth noting. The supplier is positioned for OEM production, industrial component sourcing, and repeat B2B orders rather than only one-off hardware purchases.
WENQI has a broad spring pin range covering Metric Coiled Spring Pins, stainless steel coiled pins, spiral spring pins, and heavy-duty coiled spring pins. Its published product information separates coiled spring pins into light, normal, and heavy-duty types.
This product classification is useful when the purchasing team is selecting a pin according to load requirements. Light-duty and standard-duty pins can cover general retaining and positioning applications, while heavy-duty versions are intended for higher loading conditions.
WENQI also lists custom production, factory manufacturing, different materials, and multiple spring pin designs. For buyers who need several pin types from one supplier, the product coverage is a practical point to compare.
Shanghai Sea Song has a wider industrial fastener catalog and lists ISO 8750 / DIN 7343 Coiled Spring Pins in carbon steel and stainless steel. Its product range also includes dowel pins, retaining rings, washers, cotter pins, and other fastening components.
For distributors, the broader catalog can be useful when a purchase order contains several types of hardware. The supplier can also be considered for customers looking for standard spiral spring pins rather than a fully customized component.
Wuxi Ingks Metal Parts Co., Ltd. appears among Chinese suppliers of coiled spring pins, including stainless steel versions and metric heavy/light-duty spring pins. Its listed products include stainless steel coiled roll spring pins and customized metal components.
The company is more relevant to OEM buyers that need spring pins together with other metal parts. Stainless steel options can also be considered where corrosion resistance is part of the material requirement.

Ningbo Anbor Hardware Co., Ltd. is listed for both standard and heavy-duty coiled spring pin products. Its catalog includes stainless steel DIN 7344 / ISO 8748 heavy-duty spiral pins, showing that the supplier covers different coiled spring pin duty levels.
This makes the company worth considering when a buyer needs to compare spring pin types within the same product family. Material selection can include stainless steel for applications where corrosion resistance is required.
For OEM purchasing, the exact pin standard should be stated in the RFQ. A supplier should not assume that a general "spiral spring pin" request means ISO 8750.
Jiaxing Yheng Group Limited is listed among Chinese suppliers of coiled spring pins covering several ISO and DIN specifications. Its product listings include ISO 8750 / DIN 7343 standard-duty pins as well as other coiled pin standards.
Its broader fastener range gives buyers another option when the purchasing requirement includes pins, bolts, nuts, washers, and other hardware.
For China spiral spring pin suppliers, the main point to check is the exact specification attached to the quotation. Different coiled pin standards have different duty levels and dimensional requirements, so the standard number should be included in the purchase order.
Shenzhen Huaxianglian Hardware Co., Ltd. is listed for DIN 7343 spring steel and stainless steel coiled spiral pins. Its product listings also include spring steel coiled spiral pins intended for precision applications.
Spring steel is commonly selected when the pin needs elastic recovery after installation. Stainless steel can be considered when the operating environment creates greater corrosion concerns.
For engineering buyers, the material grade should be confirmed rather than specified only as "steel." Spring steel and stainless steel have different mechanical and environmental characteristics.
Hebei Chuangke Fastener Manufacturing Co., Ltd. supplies a range of fasteners and is listed for coiled and spring pin products. Its catalog includes elastic hardened spring pin products and other industrial fastening components.
The company can be considered by wholesalers and distributors that need spring pins together with other standard fasteners. For repeat orders, buyers should confirm whether the required specification is produced as a regular item or made according to each purchase order.
How Do Elastic Spiral Spring Pins Work?
An Elastic Spiral Spring Pin is formed by rolling a strip of metal into a spiral cross-section. The finished outside diameter is normally larger than the mating hole. During installation, the coils compress and generate radial force against the hole wall.
This spring action is the main difference between a coiled spring pin and a solid cylindrical pin. The pin can absorb some dimensional variation in the assembly while maintaining contact with the hole.
The closed coiled structure also avoids the open slot found in a conventional slotted spring pin. Standard spiral spring pins are known for high radial elasticity and can allow larger bore tolerances in suitable applications.
Where Are Elastic Spiral Spring Pins Used?
Elastic Spiral Spring Pins are used in mechanical assemblies where components need to be retained, aligned, or connected without using a threaded fastener.
Common applications include:
Automotive components - linkages, levers, mechanisms, and moving assemblies
Industrial machinery - gears, shafts, handles, joints, and mechanical linkages
Electrical equipment - small mechanical connections and component assemblies
General machinery - positioning and retention of two or more components
Power transmission components - connections exposed to repeated movement and vibration
The correct pin type depends on the load, hole size, operating environment, and installation method.
What Should B2B Buyers Specify When Ordering Spiral Spring Pins?
A quotation request should contain enough technical information for the manufacturer to identify the exact product. At minimum, buyers should provide:
- Nominal diameter
- Overall length
- Product standard
- Material grade
- Duty type
- Hardness
- Surface treatment
- Dimensional tolerance
- Required quantity
- Packaging requirements
For standard-duty Elastic Spiral Spring Pins, ISO 8750 / DIN 7343 is a useful reference point. The standard defines the product type, while the material, size, finish, and quantity still need to be confirmed with the supplier.
For OEM projects, sending a drawing or sample is the better approach. It gives the Elastic Spiral Spring Pins manufacturer a clear reference for the dimensions and application requirements.
Choosing an Elastic Spiral Spring Pins Supplier in China
Price is only one part of the purchasing decision. For repeat orders, dimensional consistency, material stability, production capacity, inspection, packaging, and delivery time have a direct effect on the total purchasing cost.
A distributor may focus on MOQ and unit price. An OEM manufacturer may pay more attention to tolerance, material certification, and batch consistency. A machinery company may need custom dimensions or a specific duty level.
For companies looking for a Top Elastic Spiral Spring Pins Manufacturer in China, the suppliers above provide different options. Before placing a bulk order, confirm the standard, material, size, duty type, quantity, and inspection requirements in writing. This avoids receiving a spiral pin with the right name but the wrong specification.
