The screwdrivers in this Stanley module have black oxidised tips for increased durability. Their chrome vanadium steel bars resist bending and snapping and their bi-material tri-lobular handles increase torque and reduce slippage. The polypropylene handles feature a TPR overlay for comfort. Increased torque can be applied by using another bar through the hole. The set contains the following:T10 x 80mm, T15 x 80mm, T20 x 120mm, T25 x 120mm, T30 x 120mm and T40 x 120mm. Designed to fit the Stanley roller cabinet range.
