Hex Socket 1/2" 21 mm 1000V - NEO tools 01-190

NEO tools hex socket 1/2" 21 mm 1000V (01-190) is an insulated six-point socket engineered for use with 1/2" drive tools. The 21 mm socket combines a standard 6-point profile with insulation rated for work on electrical systems up to 1000 volts, enabling safer handling of fasteners in live installations. Constructed to meet the needs of electricians and maintenance technicians, it fits common hex nuts and bolts and is intended for professional application where electrical protection and reliable torque transfer are required.

Advantages

The insulated design provides protection when working on live circuits up to 1000 V, while the six-point profile ensures secure engagement with fastener heads to reduce rounding. Compatibility with 1/2" drives allows use with a wide range of ratchets and torque tools. The tool's durable construction offers resistance to wear during repetitive fastening tasks and maintains dimensional accuracy for consistent fit.

Suitable for

• Electrical installation and maintenance on equipment powered up to 1000 V
• Fastening and loosening 21 mm hex nuts and bolts
• Use with 1/2" drive ratchets, breakers and torque wrenches
• Workshops, industrial maintenance, and field service by electricians and technicians

Key specifications

• Drive size: 1/2" (square drive)
• Socket profile: 6-point (hex)
• Nominal size: 21 mm
• Electrical insulation rating: up to 1000 V
• Intended use: fastening and removal of hex fasteners

How to use

Select the 21 mm insulated socket and attach it securely to a compatible 1/2" drive tool. Before use, visually inspect the insulation for cracks, cuts or other damage and ensure the tool is clean and dry. Use steady, controlled force when tightening or loosening fasteners; avoid impact tools unless specified by the drive tool manufacturer. After work, clean the socket and store it in a dry environment away from chemicals and sharp objects that could damage the insulation.

Usage recommendations

Confirm that the insulation is intact before each use and do not exceed the rated 1000 V environment. For electrical safety, combine the insulated socket with other insulated tools and follow applicable electrical safety procedures, including de-energizing circuits whenever possible and wearing appropriate personal protective equipment.
