Key Features & Advantages
- Elastic Retention & Secure Fitting
The slotted tooth structure allows the pin to compress during installation and recover elastically inside the mounting hole. The resulting radial pressure helps maintain secure contact with the hole wall, reducing the risk of unintended movement during normal operation.
- Different Load-Bearing Options
Available in heavy-duty and light-duty designs, these spring pins provide different shear strength specifications for various mechanical applications. Multiple diameter and wall thickness options allow OEM buyers and equipment manufacturers to select suitable configurations according to their assembly requirements.
- Multiple Material & Performance Options
Available materials include C67S, C75S, 51CrV4, 1.4310, and 1.4568, subject to the applicable product specifications. Different material conditions and heat treatments provide options for mechanical strength, elastic performance, and corrosion resistance requirements across industrial applications.
Slotted Tooth Design & Spring Retention Performance
Elastic Compression
The open structure allows the pin to compress during insertion, accommodating the specified interference between the pin and mounting hole.
Radial Retention Force
After installation, the spring material provides outward pressure against the hole wall, helping prevent unintended pin movement during normal operation.
Wave-Shaped Tooth Structure
The formed profile contributes to the pin's elastic behavior and contact with the mounting hole, supporting its retaining function in mechanical assemblies.
Fit-Dependent Performance
Retention depends on nominal diameter, wall thickness, hole dimensions, material condition, and installation quality. Selecting the correct pin specification helps maintain consistent assembly performance.
Material Selection & Heat Treatment
Material composition and heat treatment directly influence the elastic properties, hardness, and mechanical performance of Slotted Tooth Spring Pins. Anhui Pins offers material options based on the heavy-duty and light-duty specifications, with selection depending on the intended operating environment and mechanical requirements.
| Material Category | Material Grade | Condition / Treatment | Hardness Reference |
|---|---|---|---|
| Carbon Spring Steel | C67S / C75S | Hardened and tempered | 420–510 HV |
| Alloy Spring Steel | 51CrV4 | Hardened and tempered | 420–510 HV |
| Stainless Spring Steel | 1.4310 | Cold-worked condition | According to applicable specification |
| Precipitation-Hardening Stainless Steel | 1.4568 | Age-hardened condition | 400–480 HV |
Shear Strength & Load-Bearing Capacity
Single and Double Shear Performance:
The heavy-duty specification provides minimum single-shear and double-shear values, while the light-duty specification provides minimum double-shear values. These test requirements help buyers evaluate the mechanical performance of different pin sizes.
01
Diameter-Related Load Capacity:
The minimum shear strength requirements vary with nominal diameter. Buyers should refer to the corresponding dimensional and mechanical tables rather than estimating load capacity from diameter alone.
02
Heavy-Duty and Light-Duty Selection:
Heavy-duty and light-duty pins follow separate product specifications. The required pin type should be determined by the intended application and the corresponding minimum shear strength requirements.
03
Joint Design Considerations:
Hole alignment, component thickness, supporting surfaces, and load distribution can affect actual performance. Proper joint design helps prevent uneven loading and premature pin failure.
04

FAQ
What is a wave spring pin?
A wave spring pin, also referred to here as a slotted tooth spring pin, is an elastic fastening component with a slotted cylindrical structure and a tooth-shaped profile. It compresses during installation and creates radial pressure against the mounting hole to help retain connected components.
What is the difference between heavy-duty and light-duty wave spring pins?
Heavy-duty and light-duty designs differ in their structural dimensions and specified shear strength requirements. Heavy-duty pins are intended for applications requiring higher load-bearing capacity, while light-duty pins are suited to assemblies with different mechanical load requirements. Selection should be based on the product specifications and joint conditions.
What materials are available for wave spring pins?
Available material options include C67S, C75S, 51CrV4, 1.4310, and 1.4568, depending on the applicable specification. Carbon spring steel and stainless steel options can be selected according to mechanical strength, elasticity, and environmental requirements.
What size range is available for slotted tooth spring pins?
The available nominal diameter range depends on the product type. According to the applicable specifications, heavy-duty pins cover 1–35 mm, while light-duty pins cover 2–50 mm. Length and other dimensions can be selected according to the required application.
