Socket Key 1/4" Extended 10 mm Proline 5181831 — 1/4-inch drive, 10 mm socket length

Extended 1/4" socket key, 10 mm size, Proline model 5181831. This 1/4-inch drive socket is made for use with 1/4" ratchets and bit holders to reach fasteners recessed in tight or deep spaces. Constructed from chrome-vanadium steel and heat-treated for precise hardness and durability; the socket conforms to and exceeds DIN 3124 and PN-ISO 1711 strength requirements. The specially profiled contact faces use the PRO-DRIVE system to reduce point loading and protect screw heads and flat edges from excessive wear.

Advantages

The extended design provides extra reach for hard-to-access fasteners without compromising torque transfer. Chrome-vanadium construction and controlled hardening/tempering ensure long service life and resistance to deformation. The PRO-DRIVE profiled edges lower the risk of rounding screw heads and improve grip, while manufacturing tolerances meet common industry standards for interchangeability with 1/4" tool sets.

Suitable for

• Automotive repair and maintenance
• Household DIY and appliance work
• Assembly and mechanical servicing in tight or recessed areas
• Use with 1/4" drive ratchets, bit holders and extension bars

How to use

Attach the 10 mm extended socket to a compatible 1/4" drive ratchet, bit holder or extension bar. Position the socket squarely onto the fastener head before applying torque. Use steady, controlled force to avoid sudden impacts; the PRO-DRIVE profile helps maintain grip on worn or rounded heads. After use, clean and store the socket in a tool set or socket rail to prevent corrosion.

Usage recommendations

For best results use with matched 1/4" drive tools and avoid using the socket with impact drivers unless specified by the tool manufacturer; regular cleaning and light oiling will extend service life.
