## Long description

Proline Gala 3/4 21 mm socket key (model 5188212) is a 21 mm socket made for turning nuts, bolts and valves with a 3/4-inch drive. Manufactured from chrome-vanadium steel and subject to controlled hardening and tempering, this socket offers a precise fit for secure torque transfer in mechanical, plumbing and maintenance tasks where 21 mm fastenings are used.
Advantages
The Gala socket key is produced from chrome-vanadium steel and undergoes precise hardening and tempering to ensure appropriate hardness and durability. Its durability characteristics exceed the requirements of DIN 3124 and PN-ISO 1711 standards. The socket features specially profiled edges between working faces — the PRO-DRIVE system — to reduce excessive point loading and protect screw heads and flat edges from premature wear.
Suitable for
 Turning 21 mm nuts and bolts
 Operating valves with 21 mm fittings
 Mechanical repairs and maintenance in workshops
 Plumbing and on-site service tasks requiring a 3/4" drive

How to use
Select the 21 mm Proline Gala socket and attach it securely to a compatible 3/4" drive ratchet, breaker bar or torque wrench. Place the socket over the nut, bolt or valve fitting so the faces sit squarely. Apply steady torque appropriate for the fastener and working conditions, avoiding sudden impact forces unless the tool is rated for them. After use, clean off dirt and residues and store the socket in a dry tool case.
Usage recommendations
For long service life, avoid using the socket on damaged or rounded fasteners; the PRO-DRIVE profile performs best on correctly shaped heads. Regularly inspect the socket for wear or cracks and replace it if deformation is found. Use appropriate protective equipment and follow torque specifications for the fastener and application.
