## Product Information Details<\/p>\n
The product dimensions (18.35 x 18.35 x 47.55 mm) indicate an extremely compact design, allowing work in confined spaces, while the height of 47.55 mm provides sufficient travel room for the polyurethane spring to function correctly.<\/p>\n
Extractor pins and their associated tools represent one of the most sensitive points in body repair. Using an inaccurate or unsuitable tool can cause damage to surrounding surfaces or result in improper fastening. The A4 model minimizes these risks through a stable and controlled extraction process.<\/p>\n
### The Role of the Polyurethane Spring<\/p>\n
Polyurethane (PU) material is exceptionally suitable as a spring element because it combines the elasticity of rubber with the durability of plastics.<\/p>\n
1. **Energy Absorption and Return:** The PU spring is capable of absorbing a large amount of energy during the extraction phase, and then efficiently returning this energy to quickly reposition the pin to its starting position.
\n2. **Chemical Resistance:** Polyurethane resists oils, greases, and solvents commonly used in workshops, increasing the tool's lifespan compared to traditional rubber elements.
\n3. **Thermal Stability:** Adequate thermal stability ensures that the tool's performance does not degrade significantly during normal operating temperature fluctuations.<\/p>\n
## Quality Assurance and Standards<\/p>\n
Wiel\u00e4nder+Schill is committed to the highest quality standards, which are supported by certifications:<\/p>\n
* **ISO 9001:** Certification of the quality management system guarantees that products are manufactured consistently and meet customer expectations.
\n* **ISO 14001:** Certification of the environmental management system indicates that manufacturing processes are also optimized from an environmental protection perspective.<\/p>\n
These certificates ensure that the A4 pull stud is not only an effective but also a responsibly manufactured tool.<\/p>\n
## Summary<\/p>\n
The A4 pull stud with polyurethane spring (700341) is a precise, durable, and efficient component for professional body repair. Due to its compact dimensions and integrated spring mechanism, it optimizes workflows, reduces repair time, and ensures an excellent quality result. This tool is essential for every XSeries user who prioritizes reliability and speed.<\/p>","protected":false},"excerpt":{"rendered":"
