Professional-grade 1/2" drive torque adaptor with 12-point configuration, 5,600 in-lb working torque, precision-forged alloy steel construction, and chrome finish for superior access in restricted areas.
The Snap-on 1/2" Drive 12-Point SAE 1-1/4" Standard Torque Adaptor (SRDH401) is a precision-engineered tool designed for professional aviation, aerospace, and industrial maintenance applications. Manufactured from special alloy steel and precision forged with heat treatment, this torque adaptor delivers optimum strength and durability for demanding work environments. The double hex 12-point configuration provides superior access in restricted areas by allowing the socket to engage a single hex fastener every 30° rather than every 60°, making it ideal for tight working spaces where standard tools cannot fit.
This torque adaptor features a robust construction with radius edges that resist damage and nicks during intensive use. The center-to-center length design (3 inches) enables accurate and easy torque calculations for precise fastening applications. With a working torque capacity of 5,600 in-lb, this adaptor is engineered to handle heavy-duty applications while maintaining exceptional reliability. The chrome finish provides excellent corrosion resistance and durability, ensuring long-term performance in various industrial settings.
The SRDH401 is an essential component for professionals requiring precision torque control in aviation maintenance, aerospace assembly, military applications, oil and gas operations, power generation facilities, and general heavy-duty industrial work. Its superior engineering and professional-grade construction make it an indispensable tool for any serious maintenance operation.
