When access is tight and fasteners sit deep on studs or recessed fittings, standard sockets can feel like the wrong tool for the job. This Jefferson 16 Piece 3/8" Deep Metric Impact Socket Set is made for those real-world moments—where reach, grip, and durability matter more than anything.
Each deep socket is built from Chrome Vanadium steel and finished in black phosphate to help resist corrosion in workshop conditions. The 6-point profile delivers a more secure engagement on fasteners, helping reduce the risk of rounding when torque demands climb. Designed for impact applications, it’s also suitable for use with air impact wrenches, making it an ideal everyday set for mechanics, maintenance teams, and site engineers.
With a carefully chosen spread of popular metric sizes from 7mm to 22mm, and both 3" and 6" extension bars, you can tackle awkward angles and recessed fixings without constantly changing setups. Supplied in a blow-moulded case, it’s easy to store, protect, and keep organised on the move.
