Socket 12-point 3/8" 22 mm Beta Tools 910B/22 - 12‑point drive socket

Beta Tools 910B/22 is a 12-point 3/8" drive socket with a 22 mm opening, engineered for fastening and loosening hexagonal fasteners in confined or awkward spaces. The socket’s 12-point internal profile increases contact area on fastener corners and allows easier alignment with rounded or slightly damaged heads. Manufactured by Beta Tools, this socket is intended for use with standard 3/8" drive ratchets, extensions, and torque wrenches common in professional mechanical and automotive environments.

Advantages

The 12-point design offers improved engagement on hex fasteners, reducing the risk of slipping on rounded corners while permitting operation at multiple indexing angles. Constructed from hardened alloy steel and finished for corrosion resistance, the socket balances durability with precise mating to fastener faces. Its 22 mm size covers a common range of metric fasteners, and the 3/8" drive compatibility makes it suitable for medium-torque tasks where access is limited.

Suitable for

• Automotive repair and engine maintenance
• Mechanical assembly and disassembly in workshops
• Maintenance and service tasks in confined spaces
• Use with 3/8" drive ratchets, extensions, and torque wrenches

Key specifications

• Drive size: 3/8" (compatible with 3/8" drive tools)
• Socket opening: 22 mm
• Internal profile: 12-point
• Material: hardened alloy steel with protective finish
• Typical application torque range: medium-duty automotive and mechanical tasks
• Designed for use in confined or limited-access areas

How to use

Select a compatible 3/8" drive ratchet, extension, or torque wrench and attach the socket securely to the drive. Place the socket squarely over the hex fastener, ensuring full seat on the fastener corners. Apply steady torque, avoiding sudden impacts that can damage the fastener or socket. When using torque-sensitive operations, use a calibrated torque wrench and observe the manufacturer’s torque settings for the fastener.

Usage recommendations

Use the 12-point socket for medium-torque applications and where faster indexing is beneficial; for heavily rounded or very high-torque fasteners, consider a 6-point socket of the same size to reduce risk of rounding and to provide higher torque transfer. Keep the socket clean and lightly lubricated on the drive square to prevent seizing; inspect regularly for wear or cracking and replace if any damage is found.
