ProFix 21-Piece 3/4 in Drive Impact Socket Set, 19–50 mm

What it is for

Impact sockets are not chrome sockets with a different label. They are made from a softer, tougher steel so they deform rather than shatter, and they are wall-thicker at the drive end because that is where a power tool loads them.

Using a chrome socket on an impact wrench is how a socket cracks and a fragment leaves the bay — the failure is sudden and it is the reason this range exists as its own category. The black black oxide finish is a phosphate coating rather than chrome, which is the visual difference you can check without a magnet.

Specification detail

21 impact sockets on a 3/4 in square drive, 19–50 mm, forged in CR-V steel with a black oxide finish finish and a wall thickness suited to power-tool torque. Pin and ring retaining groove; six-point with a chamfered lead-in.

• Tougher CR-V steel deforms under overload rather than shattering
• Thicker wall at the drive end, where a power tool loads the socket
• Phosphate black oxide finish rather than chrome — no plating to chip off
• Pin and ring groove holds the socket on the anvil during use
