Socket Key 1/4" Extended 8 mm Proline 5181794 for 1/4" drive sockets

Proline Socket Key 1/4" Extended 8 mm (model 5181794) is a 1/4" drive accessory designed to engage 8 mm fasteners. The extended shaft gives additional reach for recessed or obstructed fasteners, making it suitable for workshop, automotive and household use. Manufactured from chrome-vanadium steel and heat-treated to precise hardness and toughness standards, this socket key meets and exceeds DIN 3124 and PN-ISO 1711 strength requirements. The tool incorporates the PRO-DRIVE profile between the machined faces to reduce point loading and protect screw heads and flat edges from concentrated wear.

Advantages

The extended 1/4" 8 mm socket key offers improved access in tight spaces while retaining high durability due to chrome-vanadium construction and controlled hardening and tempering. The PRO-DRIVE profiled edges minimise localized stress on fasteners, reducing the risk of rounding and damage. Compliance with DIN 3124 and PN-ISO 1711 standards ensures reliable mechanical performance for repeated workshop and automotive applications.
