Specifications

Pro-Tip: When using impact hex bits, always ensure the bit is fully seated into the fastener head before engaging the impact wrench. This prevents unnecessary vibration and "cam-out," ensuring the maximum life of both your bit and the fastener. For stubborn or rusted bolts, a quick spray of penetrating oil used in conjunction with these impact bits will yield the best results.
