The ATC16MMDDC-A 16MM Head Bolt Socket is a heavy-duty, professional-grade socket engineered specifically for Detroit Diesel 50 Series and 60 Series engines. This socket is designed to properly engage OEM cylinder head bolts during removal and installation, providing accurate torque transfer and reducing the risk of fastener damage during critical engine service.
Manufactured as a 12-point socket with a 3/4" drive and an extended 4-7/8" overall length, the ATC16MMDDC-A offers the reach and strength required to access recessed head bolts commonly found on Detroit Diesel platforms. The extended length improves clearance around rocker housings and valve train components, while the 12-point profile ensures full engagement on factory fasteners for safe, controlled torque application—especially during torque-to-yield procedures.
Using standard or incorrect sockets on Detroit Diesel head bolts can lead to rounding, bolt stretch errors, or uneven clamping force that may result in head gasket failure. The ATC16MMDDC-A eliminates these risks by delivering a precise OEM-correct fit, making it an essential tool for professional rebuilders, fleet maintenance facilities, and dealership service departments.
