Why a strut nut socket? To secure shocks and struts to their mounts, the retaining nut must be torqued to its proper specification using a torque wrench. Strut nut sockets allow for the use of a 21mm wrench to hold the damper shaft allowing you to achieve proper torque. An improper torque value may result in premature mount failure - or worse.
