Socket HEX19 1/2" Proxxon 55 mm – hexagonal hand socket for torque tools

Proxxon HEX19 1/2" socket, 55 mm length, is a hexagonal hand socket designed for 19 mm fasteners. It fits 1/2-inch drive hand ratchets and torque tools, providing extended reach for tightening and loosening bolts and nuts in automotive, industrial and workshop environments. The elongated body allows access to recessed or partially obstructed fasteners while maintaining a secure 19 mm hex engagement for consistent torque transfer.

Advantages

The 55 mm length gives improved reach compared with standard short sockets, reducing the need to disassemble surrounding components. A 1/2-inch drive interface ensures compatibility with common hand ratchets, torque wrenches and drive extensions. The hexagonal profile provides reliable contact on 19 mm nuts and bolts to minimize rounding and slippage when applying torque. The straightforward design makes it suitable for repetitive professional tasks as well as occasional DIY use.

Suitable for

• Automotive repair and wheel/engine fastener work
• Machinery maintenance and industrial bolted connections
• Workshop tasks where extended reach or partially recessed fasteners occur
• Using with 1/2" drive torque wrenches and hand ratchets

Key specifications

• Drive size: 1/2 inch
• Socket profile: 6-point hex (hexagonal)
• Nominal size: 19 mm
• Overall length: 55 mm
• Intended use: hand ratchets and torque tools for tightening/loosening

How to use

Select a compatible 1/2" drive ratchet or torque wrench and attach the socket to the square drive. Seat the 19 mm hex socket fully onto the fastener to ensure full contact on opposite flats before applying force. For torque-controlled applications, set the torque wrench to the required value and apply smooth, steady force. If using with extensions, verify secure connections and re-check torque after initial tightening where safety-critical fastenings are involved.

Usage recommendations

Use the socket only with hand-operated 1/2" drive tools as specified. Avoid impact tools unless the socket is explicitly rated for impact use. Keep the socket clean and inspect for wear or rounding before use; replace if edges are worn to maintain safe and accurate torque application.
