Socket wrench bit NEO tools 1/2" 19 mm hex impact long (12-319)

NEO tools 1/2" 19 mm hex impact long socket (model 12-319) is a heavy-duty, extended-reach socket designed for use with 1/2" drive impact wrenches and air or electric impact drivers. The six-point hex profile fits 19 mm fasteners to provide a strong, concentric grip that reduces rounding. Constructed and heat-treated for impact applications, this long socket offers the extra length needed to reach recessed nuts and bolts in automotive, industrial maintenance and repair situations.

Advantages

The long design increases access to deep or recessed fasteners while maintaining a secure fit on 6-point heads. Impact-rated construction and appropriate heat treatment improve durability under repeated high-torque loading. The 1/2" drive interface ensures compatibility with standard impact tools, and the 19 mm hex size covers a common range of bolts and nuts in automotive and machinery applications.

Suitable for

• Automotive wheel and underbody repairs requiring extended reach
• Industrial maintenance and machinery servicing with recessed fasteners
• Heavy-duty repair and assembly where impact wrenches are used
• Any workshop tasks needing a 19 mm hex socket with extra length

Key specifications

• Drive size: 1/2" (square drive compatible with 1/2" impact tools)
• Hex profile: 6-point for improved contact with fastener flats
• Socket size: 19 mm across flats
• Length: extended/long design for recessed fasteners
• Material and treatment: impact-rated, heat-treated steel suitable for high-torque use

How to use

Select the 19 mm socket for the matching fastener, attach the socket securely to a 1/2" impact wrench or breaker bar, and engage the tool at low speed to seat the socket on the bolt or nut. When using an impact wrench, maintain steady pressure and use controlled bursts to avoid over-torquing. After loosening or tightening, visually inspect the socket and fastener for wear or damage and replace the socket if deformation is found.

Usage recommendations

Use this NEO tools long impact socket only with impact-rated 1/2" drive tools. Avoid using the socket with hand ratchets not specified for impact sockets. Regularly inspect for cracks, rounded edges or corrosion and replace the socket if damage is detected. For precision torque requirements, finish tightening with a calibrated torque wrench rather than an impact tool.
