4853 1/2″ Drive Dual-Drive Extension Bar Set Series delivers 2-in-1 access flexibility for heavy-torque mechanical maintenance. Based on the 4802 dual-drive series, each bar incorporates a stepped, radiused male drive anvil. Technicians can seat a socket halfway to access hard-to-reach fasteners with a 15° angled design omnidirectional wobble angle, or press the socket completely home to lock it into a rigid straight bar capable of handling heavy breakaway torque.

Feature
How does the dual-drive feature work on the 4853 series extension bars?
The bars use the stepped 4802 dual-position anvil. When a socket is inserted partially to the first detent, it enters wobble mode, providing up to $15^\circ$ of multi-directional swivel to reach angled bolts. Pushing the socket fully onto the anvil engages rigid mode, locking the socket in a straight line for heavy manual torque.
What is the difference between the 4853-10, 4853-15, and 4853-18 sets?
Each set provides a distinct 3-piece length combination tailored for specific service clearance requirements:
- 4853-10: Contains 50mm (2″), 75mm (3″), and 125mm (5″) bars (totaling 10 inches), ideal for compact engine bays and brake caliper work.
- 4853-15: Contains 50mm (2″), 75mm (3″), and 250mm (10″) bars (totaling 15 inches), offering wide versatility between stubby reach and deep access.
- 4853-18: Contains 75mm (3″), 125mm (5″), and 250mm (10″) bars (totaling 18 inches), designed for heavy truck chassis, subframes, and transmission bell housings.
Can these extension bars handle heavy manual torque without bending?
Yes. Forged from high-grade Chrome Vanadium steel and heat-treated under strict factory controls, these bars meet and exceed international DIN 3123 and ISO 3316 torque specifications in both rigid and wobble modes.
Can individual bars within the sets be connected together?
Yes. Each extension bar features matching 凸 ½″ male anvils and 凹 ½″ female receivers with internal ball detent channels. They can be linked in series (e.g., Adding 75 mm and 125 mm gives a total of 200 mm.
