Why this one
Plug sockets 14, 16, 18 and 21 mm (M380039-C)
Mowers, UTVs, ATVs, generators and outboards commonly use 14, 16, 18 and 21 mm plugs, so a shop needs all four. Each 3/8 inch drive socket has a rubber insert that grips the plug, so it lifts out of a deep well instead of dropping.
Flexible 16 mm plug socket (M380041-C)
On many V-twin engines the plug sits under a shroud where a straight socket cannot line up. The flexible 16 mm socket bends to reach it, and its rubber insert holds the plug as it comes out.
Ratchet, extension and universal joint (3800FRP, M380020-C, M380030-C)
Plug sockets need something to turn them. The 3/8 inch drive 45 tooth ratchet turns them, the 75 mm (3 inch) extension reaches down the plug well, and the universal joint takes plugs set at an angle.
Feeler gauge 0.05 to 1.0 mm (FG20100)
A new plug is gapped before it goes in, because the gap out of the box is not always right for the engine. The metric feeler gauge covers 0.05 to 1.0 mm with a 100 mm (3.9 inch) blade length to check it.
