COMPLETE IMPACT NUT DRIVER SET: Hex nut driver set combines 10 metric magnetic nut drivers (5mm, 5.5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm) and 8 SAE magnetic drivers (1/4", 9/32", 5/16", 11/32", 3/8", 7/16", 1/2", 9/16"). The non-magnetic deep nut driver (8mm, 10mm, 13mm, 17mm Metric; 5/16", 3/8", 7/16", 1/2", 9/16(15), 5/8"(16), 3/4"(19) SAE,) tackle hard-to-reach bolts, while the 17mm wing nut driver, 6'' bit extension and 1/4" 3/8" 1/2" drill socket adapter expand compatibility for automotive, constructionCR-V STEEL FOR ENHANCED HARDNESS: Each nut driver in impact driver socket set is precision-crafted from high-temperature quenched CR-V steel, specially engineered to deliver enhanced hardness and long-lasting durability. The reinforced thick-wall design further boosts resistance to deformation, while the manganese phosphate coating offers reliable corrosion protection even in tough working conditionsPREMIUM MAGNETIC RETENTION: Embedded magnets in the 1/4" magnetic nut driver superior adsorption force,during disassembly, the magnet nut driver's magnetic force counteracts gravity, ensuring nuts don't fall out.The magnetic nut drivers retain full strength after repeated use, ensuring reliable performance in confined spaces and elevated work areas, enhancing safety and efficiencyEFFORTLESS MULTI-SCENARIO USE: This magnetic nut driver set for impact drills tackles any job-install drain pipes, mount appliances, lift car jacks, replace exhaust parts, build wooden structures, or hang roof hooks. Strong magnets keep nuts from falling during overhead work, and the 1/4" hex shank fits drills, screwdrivers, and impact tools. Impact socket set is perfect for home improvement, car repairs, woodworking, and professional machine maintenanceVISIBLE MARKINGS & PORTABLE BOX:This drill socket set features nut drivers with laser-engraved size marks for easy ID, resisting wear in oily/dusty spots-great. Stored in a tough, compact tool case, the set stays secure during transport and fits nicely in work trucks, or backpacks.If you encounter any questions while using this set, please feel free to talk to usAlloy Steel
