Titan Spline Socket Sets Titan spline socket sets are available in both SAE and metric dimensions， covering a range of the most popular sizes. They're machined from chrome vanadium steel， with precision teeth engaging more of the fastener to reduce stress and permit greater torque―without stripping the head or damaging the tool. These versatile sockets will also loosen or tighten other style heads， such as 6-point， star， square， 12-point (triple square)， and damaged fasteners. A convenient socket rail is included to keep your attachments organized.
