PB Swiss Tools Ball Point Hex Key Set w/Bolt Holding Ring, sizes 1.5-10mm, long-type, chrome-plated

Every PB hex key is held to tolerances less than a human hair for perfect dimensional accuracy. 1.5 and 2mm in set do not have the Circlip holding ring due to their small size. PB's spring steel, despite a hardness of 58-60HRC, allows toughness/elasticity in its hex keys. All PB Swiss Tools are 100% Swiss-made. Every PB Swiss Tools product comes with an unlimited lifetime guarantee.
