The IRWIN 3/8 Hex-Drive 9/16 Deep Well Socket is a high-quality tool designed for easy use when working on car, truck, and heavy machinery repairs at home or in professional garages. It features a durable construction from alloy steel with its black oxide finish to resist rust and corrosion while providing superior torque and strength for fastening purposes. Its deep well design provides enough depth to access most of the nuts' threads for better performance on jobs where space is limited. The 3/8 hex-drive style allows use in combination with most common air, power and socket wrenches available in the marketplace today while providing a tight grip on both thin and thick nuts or bolts without slipping or rounding edges as well as offering less chance of damage when applying extra torque. The 12 point design offers an exact fit in fastening into most standard square recess holes preventing over tightening or cross-threading while also reducing wear on the nut and bolt as well as extending its lifespan making it perfect for automotive garages, heavy industry maintenance teams and equipment repair services that require constant use of sockets.
