Proto J5438 Hand Socket 1-3/16 in 12-point 1/2 in Drive

Product Description

The PROTO J5438 is a 12-point hand socket designed for 1/2 inch drive ratchets, breaker bars, and extensions. Built from alloy steel with a chrome-plated finish, it accepts a 1-3/16 inch fastener and measures 1-3/4 inches in overall length, placing it in the standard-length category. The chrome coating provides corrosion resistance for shop and field use. This socket meets AS4984A and ASME B107.110-2012 standards, making it a compliant choice for professional tooling inventories. Licensed mechanics, industrial maintenance techs, and heavy equipment service crews will find this a dependable addition to any 1/2 inch drive set.

The J5438 is suited for automotive, fleet, and industrial maintenance applications where 1-3/16 inch fasteners are common. Standard-length geometry works well in accessible bolt locations on engine assemblies, suspension components, and structural fasteners. The 12-point design engages fasteners from more rotational positions than a 6-point socket, which is useful in tight swing-arc situations. This socket is appropriate for both hand-torque and torque-wrench applications in professional service environments.

Key Features

• 1-3/16 inch socket size for common large-fastener applications
• 12-point design allows engagement at more rotational positions
• 1/2 inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• Alloy steel construction for strength under high-torque loads
• Chrome-plated finish resists corrosion in shop environments
• Meets AS4984A and ASME B107.110-2012 standards

Compatibility

Designed as a standard 1/2 inch drive hand socket compatible with any 1/2 inch drive ratchet, torque wrench, or extension bar meeting ASME B107.110-2012 tooling standards.

Installation Notes

Install and remove using a 1/2 inch drive ratchet, breaker bar, or calibrated torque wrench. Always confirm the socket is fully seated on the fastener before applying torque. Do not use impact drivers with this hand socket unless the tool is rated for impact-socket use. Follow applicable torque specifications from the equipment manufacturer.
