Advantages

The Proline 1/2" 6-point 30 mm socket is made of chrome‑vanadium steel and heat‑treated to achieve consistent hardness and strength. Its specially profiled contact edges use the PRO‑DRIVE system to reduce point loads on fastener corners and minimize rounding of bolt and nut heads. The socket's durability exceeds DIN 3124 and PN‑ISO 1711 requirements, ensuring reliable service life in professional applications.
