Juego de 1/2 pulg. de dado hexagonal de 21 mm, acero AF

A 1/2" drive socket specifically adapted for accommodating plastic inserts. The inner form and length of the socket securely grasp the plastic inserts, ensuring effective retention. This design facilitates the transmission of optimal drive torque to the screw head. The potential for metallic contact between the socket and hex head is mitigated, thereby preventing contact corrosion. This construction enhances the longevity and performance of the socket in diverse applications.
