Socket 1/2" 19 mm, Topex 38D719, 6-point hex drive

Topex 38D719 is a 6-point hex socket with a 1/2" drive and a 19 mm opening designed for reliable engagement with hex fasteners. Made to fit standard 1/2" drive ratchets, torque wrenches and breaker bars, this socket is intended for use where secure contact with bolt and nut faces is required to apply turning force without rounding corners.

Advantages

This 6-point socket offers improved contact with the flats of fasteners compared with 12-point designs, reducing the risk of slip and damage on worn or high-torque bolts. The 1/2" drive size provides compatibility with a wide range of hand tools commonly used in automotive and mechanical work. Its 19 mm size covers many standard applications, making it a practical component in professional and home tool kits.

Suitable for

• Automotive maintenance and repairs involving 19 mm hex fasteners
• Mechanical assembly and disassembly tasks
• Workshop, garage and industrial maintenance where 1/2" drive tools are used
• Tightening and loosening bolts and nuts with torque control using compatible torque wrenches

Key specifications

• Drive size: 1/2" (compatible with standard 1/2" drive tools)
• Socket type: 6-point hex
• Nominal size: 19 mm
• Typical applications: bolts and nuts with 19 mm hex heads

How to use

Select the 19 mm socket when the fastener head matches the nominal size. Fit the socket securely onto the 1/2" drive tool — ratchet, breaker bar or torque wrench — until it clicks or seats firmly. Use steady, controlled force when applying torque and avoid sudden impacts unless the socket and tool are rated for impact use. When using a torque wrench, set the required torque value and apply force until the wrench indicates the set torque.

Usage recommendations

Inspect both the socket and fastener for wear before use. Use the 6-point socket for high-contact engagement on hex heads to reduce rounding. For high torque applications, use a suitable torque wrench or breaker bar and avoid applying extension methods that exceed the tool's rated capacity. Store the socket in a dry place to prevent corrosion.
