Real World Features
Prestacycle Standard Bit sets are made of CRV Steel and include a unique feature allowing Hex bits to adapt to bolts of varying quality. Steel Hex bolts often have variations in actual bolt hole size, and potentially some variations in shape. Our CRV bits are tapered to fit these variations. These bits will insert until the reach full grip contact and will have no wobble. Depending on the bolt, this bits will not insert fully to the bottom, but instead will create a superior grip with no rounding.
