i don't know what to get, a Damping Adjustment (hex wrench) or Spanner Wrench

the car has APEXi N1 99 spec installed when i bought it, and the thingy for me to adjust the N1's was misplaced by the previous owner.

what is the difference between Spanner Wrench and Damping Adjustment (hex wrench)?

which one should i get?

and here is where i could get them http://www.andysautosport.com/honda/...ssories/apexi/

any info would be appreciated

thanks

 

the hex one should have a hex shape....the other should b kinda round...
