SK 89039 Superset

The SK 89039 Superset is a 33-piece screwdriver or bit socket set. This comes at a discounted price of $250 on Amazon with free shipping. All bit sockets have a through-hole design that makes them easier to replace when bits are broken.

Meanwhile, the bits are made from high strength S2 steel with C-Clip retention groove in hex end. The said feature allow you to work more conveniently with any automotive project since they provide a more secure hold on the nut.

The new bit holder design is better than the old version since it stops the bit from slipping out the socket. Aside from this, the sockets are also made durable with their SuperKrome finish that has a maximum corrosion resistance.

The SK 89039 Superset not only ensures that you have the right tool to use for most projects but also guarantees that you will be able to use it for a long time.

Plus, if you use a ratchet, T-handle or spinner handle, and universal joints, greater leverage or torque power is also expected. All of the tools are packed inside a molded plastic set and come with the manufacturer’s lifetime warranty.
