MST45S GripEdge 45-Piece RPT Master Star Driver Set I Including Star + Tamper Proof Star + E-Star

Introducing the GripEdge R.P.T. (Rounding Prevention Technology) 45-Piece Master Star Driver Set. Designed to replace standard tools, each socket's unique bi-directional design loosens and tightens both new and damaged fasteners. Patented R.P.T. technology delivers up to 50% more torque on new fasteners and up to 400% more torque on compromised ones, so rounded or worn fixings come undone without drilling or cutting.

The set covers Star sizes T6 to T100, tamper-resistant Star sizes T8H to T55H and E-Star sizes E4 to E24 across 1/4", 3/8" and 1/2" square drives. E-Star sockets are made from Cr-Mo steel for strength and durability, while the precision-machined S2 steel star bit sockets are corrosion-resistant with oversized, ink-filled size markings that are easy to read in a busy workshop.

All 45 pieces pack into a premium carry case with a removable foam insert, ideal for automotive and industrial work. "It's all about the grip!"
