Check the listing for details. HARLEY DAVIDSON CLUTCH ADJUSTMENT JAM NUT WRENCH TOOL SOCKET 11/16" and 9/16". Condition: New. Listed at 11.99 USD. Heavy Duty HARLEY DAVIDSON JAM NUT WRENCH TOOL SOCKET 11/16" and 9/16" *Guaranteed. *Used to loosen and tighten the jam nut on a Harley clutch. *Fits better then similar sockets because the outside diameter is smaller. I've had people send me messages about other sockets being too thick. *Makes it much easier. Easy to adjust the clutch rather than trying to squeeze a spanner in, the socket fits nicely with allen key inside it, spanner on the outside. *2 in 1 socket 11/16" and 9/16" (14mm,17mm). *Made in the USA. Lifetime Warranty. I will replace if the socket does not hold up (none of these have ever failed so I've never had to send any replacements). *Note the 7/32 allen wrench picture is to demonstrate how it works. Listing does not include allen wrench. Includes the 2 piece's in the last picture. All of these have a protective anti rust coating on them. New and never used. Please feel free to ask any questions you might have. Thanks for looking.
