Proto 3/4" Drive Socket 30 MM - 12 Point J5530M-SBD

Proto's J5530M is a professional-grade 3/4-inch drive 30mm socket designed for high-torque industrial and mechanical applications. This metric socket features a 12-point configuration, which provides twice the engagement positions of a standard 6-point socket. This allows for faster indexing and significantly better accessibility in tight quarters where handle swing is limited. It utilizes Proto's patented TorquePlus™ design, a high-performance drive configuration that allows the socket to grip the flats of the fastener rather than the corners. This radius-corner geometry minimizes rounding, protects expensive hardware, and provides the grip necessary to turn worn, rusted, or damaged fasteners. Forged from high-strength alloy steel, it is built to meet or exceed ASME B107.110-2012 and SAE AS955 standards.
Key Features
TorquePlus™ Drive System: Advanced internal geometry shifts contact stress away from fastener corners and onto the flats, reducing rounding and maximizing torque transfer. High-Access 12-Point Profile: Offers double the indexing positions for faster alignment and better maneuverability in restricted work environments. Industrial Alloy Steel: Forged and heat-treated for maximum strength and long-term durability under heavy-duty professional use. Satin Finish: Typically features a satin finish to provide a professional look and a textured surface that is easier to grip in oily or greasy conditions. Optimized for Maintenance: Specifically designed to effectively grip and turn fasteners that are already worn, rusted, or made from soft materials. Standard Metric Dimensions: Features a 30mm opening size with an overall length of 2-1/8 inches, designed for heavy-duty 3/4-inch drive tools. Product Weight: Weighs approximately 0.65 lbs, providing a robust and durable profile for high-torque industrial tasks.
