Heavy Duty 1/2" Dr. 12 Pt Line Socket – Length: 4 1/8"
*This socket clears drive yoke to remove cap screws*
The ATC 12DRLINE Heavy-Duty 12-Point Line Socket is a rugged, professional-grade socket designed for high-torque fastener applications in heavy-duty diesel service, driveline work, and industrial maintenance. Built with a 1/2" drive and 12-point head, this line socket delivers maximum flexibility and strength when working on drive lines, transmission housings, pump adapters, manifold bolts, and other 12-point fasteners commonly found on medium and heavy-duty engines.
Manufactured from premium chrome-molybdenum steel and heat-treated for impact resistance, the ATC 12DRLINE provides excellent durability under repeated high-load use in demanding shop environments. The 12-point configuration allows for faster engagement from multiple angles and is especially useful in tight spaces where a 6-point socket may not fit or index easily. Whether paired with an impact wrench, breaker bar, or torque wrench, this socket delivers consistent performance and extended service life.
Key Features & Benefits
- Heavy-duty chrome-moly steel construction with heat-treated durability
- 1/2" drive size compatible with standard impact, breaker, and torque tools
- 12-point head design allows multi-angle fastener engagement
- Extended 4 1/8" length clears drive yokes for cap screw removal
- Ideal for driveline fittings, transmission fasteners, and general service work
- Built for professional diesel repair shops and fleet maintenance environments
Typical Applications
- Transmission and driveline fastener service
- Heavy-duty truck and diesel engine repair
- Fleet maintenance and industrial equipment repair
- General high-torque automotive and commercial vehicle applications
Why It Matters
Proper fastener engagement directly affects service speed, safety, and component protection. Inferior sockets can round bolt heads, slip under load, and cause unnecessary downtime. The ATC 12DRLINE Heavy-Duty 1/2" Drive 12-Point Line Socket provides secure engagement, durable construction, and reliable high-torque performance—helping technicians complete demanding driveline and diesel service tasks efficiently and confidently.
