Socket bit 20 mm 6-point square 1/2" drive impact STANLEY 891201

Impact socket 20 mm, 6-point configuration, 1/2" square drive designed for heavy-duty fastening and loosening tasks. Manufactured by STANLEY to meet the demands of impact wrenches, ratchets and torque tools, this impact-rated socket provides a secure fit on hex fasteners and is built to withstand the shocks generated by pneumatic and electric impact tools. Its 6-point geometry reduces rounding on fastener heads and the 1/2" square attachment ensures compatibility with a wide range of professional drive tools.

Advantages

The 6-point profile improves contact with fasteners, reducing the risk of slippage and rounding compared with thin-wall or worn sockets. Constructed for impact use, the socket resists cracking and deformation under repeated high-torque applications. The 20 mm opening matches a common fastener size used in automotive and industrial maintenance, while the 1/2" square drive offers broad compatibility with standard impact accessories and extension bars. The durable finish helps protect against corrosion and facilitates easier cleaning after use.

Suitable for

• Automotive wheel and engine maintenance requiring 20 mm fastener access
• Industrial machinery assembly and disassembly where impact tools are used
• Preventive maintenance and repair tasks in workshops and service vans
• Tightening and loosening of bolts and nuts with high torque demands

Key specifications

• Socket opening: 20 mm
• Point configuration: 6-point (hex)
• Drive type: 1/2" square drive (impact-rated)
• Intended use: impact tools, ratchets and torque wrenches
• Material properties: engineered for impact resistance and durability

How to use

Select the socket and attach it securely to a compatible 1/2" drive impact wrench, breaker bar or ratchet. Ensure the socket fully seats on the fastener head before applying torque. When using an impact tool, apply controlled bursts rather than continuous trigger pull to maintain control and reduce stress on the fastener. After use, inspect the socket for cracks or deformation and clean off grease and debris to prolong service life.

Usage recommendations

Use only with tools and extensions rated for 1/2" square drive and impact service. Do not use impact sockets on manual hand tools as the thicker walls and specific heat treatment may differ from standard hand sockets. Replace the socket if any visible damage is present; damaged impact sockets can fail under load.
