1/2" Drive Deep Impact Socket-21mm (NS.21L) -suitable for use with heavy duty wheel lugs/bolts.
Drilled for use with retainer pins and o-rings (for additional
safety) or simple "ball retainer" attachment to your
impact tools. Made in France. (Note-if you need a thinwall socket, go with the NSB.21)
The current NS.21LA has the same
specs but is made in Taiwan.
