Installation Notes

Impact-rated bits should be used only with impact drivers or impact-rated screwdrivers, not standard drill-drivers where bit shatter risk increases under sudden torque loads. Inspect bits before each use and replace any that show cracking, rounding, or deformation. Store the case in a dry location to prevent corrosion on bit tips. No special certifications or codes govern bit set use, but always follow tool manufacturer torque recommendations.
