Key Features:

8 PIECE SET of Long 2" QUICK CONNECT Hex Key Allen Bits (For Impact Drivers & Drills etc.)

These Hex Key Allen Bits Are 2" Long, And They Have The 1/4" Quick Connect Hex Shank. They are made to fit impact drivers, and once they are inserted into the impact driver, they will not fall out. They are also compatible with corded drills, cordless drills, electric screwdrivers, and much more!

This is an 8 PIECE SET of METRIC Hex Key Allen Bits - But They Also Fit Most SAE (American) Size Hex Allen Screws & Bolts Too!

These are INDUSTRIAL GRADE Bits, and they are EXTREMELY Durable!

This Set Includes the Following Sizes:  1.5mm (H1.5), 2mm (H2), 2.5mm (H2.5), 3mm (H3), 4mm (H4), 5mm (H5), 6mm (H6), and 8mm (H8).

These quick connect hex key bits are super handy because they will not fall out of your impact driver like the shorter, non quick connect ones do. Also, the shank of these bits are MAGNETIC, which means that they will not fall out of electric screwdrivers either. 

This Set Includes All of The Most Popular Sizes (which means that they will fit almost any type of hex allen head screw or bolt, whether it is Metric or SAE!)
