When selecting vibration-resistant and waterproof thread lockers for the electric vehicle industry, prioritize high-frequency vibration-resistant and waterproof thread fasteners, which are suitable for electric bicycle screw fixing scenarios, meet the anti-loosening and waterproof requirements during operation, and provide clear guidance for procurement selection.
Direct Selection Conclusion
For the screw fixing scenarios of electric bicycles that require high-frequency vibration resistance and waterproofing during operation, medium-strength thread fasteners with high-frequency vibration resistance and waterproof sealing properties should be selected. This avoids difficulty in subsequent disassembly caused by high strength, while meeting both anti-loosening and waterproof requirements.
Core Parameters to Confirm Before Procurement
| Parameter Item | Requirement Standard |
|---|---|
| Vibration Resistance Performance | Must pass 10-2000Hz high-frequency vibration test, no screw loosening after test |
| Waterproof Performance | Must have IPX7 or higher waterproof capability to prevent rainwater from seeping into screw gaps |
| Strength Grade | Select medium strength (thread locking strength 10-25N·m), balancing anti-loosening and disassembly convenience |
| Temperature Resistance Range | Adapt to the operating temperature of electric bicycles (-40℃ to 120℃) |
Selection Steps
- Step 1: Clarify screw specifications and material, such as M5-M8 steel screws, confirm the applicable specification range of the thread locker
- Step 2: Check if product parameters meet vibration resistance and waterproof requirements, exclude general industrial thread lockers
- Step3: Confirm the product is a single-component, easy-to-apply type, suitable for mass installation operations
- Step4: Prioritize corrosion-free types to avoid damaging screws or metal parts
Sampling and Testing Recommendations
Before procurement, apply for sample sampling. After installing the sample on electric bicycle screws, conduct two core tests: First, high-frequency vibration simulation test to verify the anti-loosening effect in operation scenarios; Second, waterproof immersion test to confirm no screw rust or loosening after 24 hours. Only after passing the test can bulk procurement proceed.
Common Selection Misconceptions
- Misconception1: Blindly selecting high-strength thread lockers leads to difficulty in subsequent screw disassembly and increases maintenance costs
- Misconception2: Only focusing on vibration resistance while ignoring waterproof properties, leading to rainwater seeping into screw gaps and causing rust
- Misconception3: Selecting general-purpose thread lockers that are not optimized for high-frequency vibration scenarios of electric bicycles, resulting in insufficient anti-loosening effect
Bulk Procurement Communication Checklist
| Communication Item | Content to Confirm |
|---|---|
| Product Adaptability | Applicable models for corresponding screw specifications, single-unit capacity |
| Application Support | Curing time, whether supporting accelerant is needed, application temperature requirements |
| After-sales Guarantee | Whether sample testing and technical guidance services are provided |
| Delivery Arrangement | Bulk production cycle, logistics delivery method |
Common Questions
Q: Can ordinary thread lockers be used for electric bicycle screws? A: Not recommended. Ordinary thread lockers are not optimized for high-frequency vibration scenarios, prone to loosening, and most do not have waterproof properties, failing to meet the anti-loosening and waterproof requirements for outdoor use of electric bicycles.
Purchasing Frequently Asked Questions
What information is required before bulk purchasing?
It is recommended to provide application scenarios, substrate materials, target strength, temperature resistance requirements, curing methods, packaging specifications, and estimated purchase quantity to facilitate quick determination of product direction.
Is a sample test required first?
Industrial adhesives are greatly affected by materials, surface treatment and usage environment. It is recommended to conduct a sample test before bulk purchasing, then confirm the model and packaging specifications.
