Professional-grade 1/2" drive torque adaptor with 12-point SAE configuration, precision-forged alloy steel construction, 5,280 in-lb working torque capacity, and chrome finish for superior durability and restricted-area access.
The Snap-on 1/2" Drive 12-Point SAE 1-1/8" Standard Torque Adaptor (Model SRDH361) is a precision-engineered tool designed for professional mechanics and technicians in aviation, aerospace, and heavy-duty applications. Manufactured from special alloy steel, this torque adaptor features precision forging and heat treatment to deliver optimum strength and durability in demanding work environments. The double hex 12-point configuration allows the socket to engage single hex fasteners every 30° rather than every 60°, providing superior access in restricted areas where traditional 6-point sockets cannot fit.
This adaptor combines professional-grade construction with practical design features that enhance usability and longevity. The radius edges are specifically designed to resist damage and nicks during regular use, while the center-to-center length marking facilitates easy and accurate torque calculations. With a working torque capacity of 5,280 in-lb, this adaptor is built to handle the rigorous demands of professional maintenance operations. The chrome finish provides corrosion resistance and a professional appearance, making it ideal for both shop and field applications.
The 1-1/8" adaptor is part of Snap-on's comprehensive torque adaptor lineup, offering compatibility with 1/2" drive tools and featuring specifications including a head diameter of 1.641 inches at the wrench end and 1.040 inches at the square end. With an overall center-to-center length of 3 inches, this adaptor is engineered to meet the exacting standards required in aviation, aerospace, military, and general industrial maintenance applications.
