Makita Magnetic Nut Driver Set for Impact Drivers and Drills

From Mr. HVAC This is the absolute best set of drivers for the HVAC technician. I own two sets of these. One set is in my home tool bag and the other is in my work tool bag. This set includes your common sizes which are 1/4”, 5/16”, and 3/8”. These drivers are extra long and magnetic, which is very handy. I have included a related product which is a short multi-size driver which is needed for tight spaces. You will want both of these. I carry both. Adapted from Amazon Magnetic nut driver provides convenient pick-up and retention of hex fasteners. lobular design drives along flats to reduce rounding of hex fasteners. Flat edges at hex opening for full contact with flanged hex head screws. Performance-optimized S2 steel construction for extended life. Calibrated heat treating process for added durability. The socket sizes are 1/4”, 5/16”, and 3/8”. These are the most common.
