Milwaukee 3/8 Drive Socket Metric Deep-12MM (4932478356)

Description

Genuine Milwaukee · Part no. 4932478356

A deep 12mm chrome socket on 3/8in drive. Twelve millimetres is a size you meet often on Japanese and Korean cars, where an M8 bolt or nut commonly has a 12mm head, and the extra depth lets the socket pass over a stud or a long bolt end to grip the nut properly.

Good to know

• Is 12mm the same as the 13mm on my European car? No. Both are used for M8 fasteners by different makers, and the millimetre difference is enough to round a head, so match the socket to the nut.
• Which jobs need the deep version? Nuts on studs, such as manifold, heat shield and bracket fixings, and nuts on long bolts. Where the head is flush and space is short, use the standard length.
• What should I drive it with? A 3/8in ratchet, plus an extension where the nut is buried. Use a spanner on the socket's flats where a ratchet cannot swing.

Which one?

For low-clearance 12mm heads, the Milwaukee 3/8 Drive Socket Metric Standard-12MM (4932478342); to reach buried nuts, the Carlyle 3/8 Drive 250mm Chrome Extension (CEXT3810).
