Carlyle 1/2 Drive 16mm 12 Point BI Hex Spark Plug Socket (CSSP12016M)

Description

Genuine Carlyle · Part no. CSSP12016M

Carlyle's CSSP12016M is a 16mm spark plug socket with a 12 point (bi-hex) opening on 1/2in drive, 64mm long, in polished chrome vanadium. A rubber insert inside holds the plug, so it comes up out of a deep plug well with the socket. 16mm (5/8in) is one of the commonest plug sizes, and the bi-hex shape also suits slim 12 point plug heads.

Good to know

• Will it fit down my plug well? Its outside diameter is 21.85mm, so the well must be wider than that. The inside depth is 37.8mm, enough to hold the plug body while the insert grips it.
• Does it fit ordinary 6 point plugs as well? Yes. A 12 point socket fits both hex plugs and slim 12 point plugs of its size; a 6 point socket only fits hex ones.
• How do I change plugs without damage? Work on a cold engine, start each new plug by hand to avoid cross-threading the head, then tighten to the plug or engine maker's figure.

Which one?

For 13/16in plugs, the Carlyle SSP1226 is the size up; for a long reach into deep wells, the Carlyle Spark Plug Socket 16mm 21mm-155mm Long (CWSP3001014M). The 3/8 drive CSSP3820 suits smaller ratchets.
