M7 NC-4620QN3 Extended-Anvil Air Impact Kit
The M7 NC-4620QN3 combines a 1/2-inch air impact with a 2-inch extended anvil and three double-ended flip sockets. The kit mixes one SAE socket pair with two metric pairs, so check the actual fastener openings rather than assuming a complete size range.
Specifications and included details
- 1/2-inch drive, 2-inch extended anvil and listed tool weight 3.7 lb.
- Flip socket pairs: 3/4 x 13/16 inch, 17 x 19 mm and 21 x 22 mm.
- 200–350 ft-lb forward torque; 450 ft-lb maximum reverse torque.
- 9,000 RPM free speed, 4.4 CFM average air consumption and 90 PSI specification.
Before ordering
Compare the three socket pairs with your fasteners and allow space for the extended anvil plus socket. The anvil extension changes access geometry; it does not itself establish increased torque. Check supply requirements and finish torque-critical tightening with a torque wrench.
Product questions and answers
Which flip-socket openings are included?
The listing specifies three pairs: 3/4 and 13/16 inch, 17 and 19 mm, and 21 and 22 mm. Other openings are not established as included.
Does the 2-inch anvil mean a 2-inch socket drive?
No. The drive remains 1/2 inch. The 2-inch specification describes the extended anvil, not the socket drive size.
Does a longer anvil increase torque?
Length alone does not establish increased torque. Compare the listed 200–350 ft-lb forward and 450 ft-lb maximum reverse ratings, and choose the extension for access.
