Stanley 94-158 Extra-Long Ball-Point Hex Key Set, 9 Piece (1.5-10 mm)

The Stanley 94-158 is a 9-piece set of extra-long metric ball-point hex keys, sized 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10 mm, for fastening and loosening screws. Stanley makes the keys from S2 steel hardened to HRC 60 ±2, which it says gives 20% more torque than Cr-V. The spherical head reaches screws at up to 25 degrees off line, and Stanley names machines and automobiles among the uses. It describes the set as durable and long-lasting.
