Set of Ten – Head Nuts – Suzuki Hayabusa, Yamaha R1 (1999-2003) and for use with any application requiring the smaller 3/4″ base diameter. (10 mm x 1.25 with 3/4″ base dia.) Super heat treated cylinder head nuts are a must for high output engines.
Help prevent blown and leaking head gaskets caused by the threads in the soft stock nuts stretching.
APE nuts are machined from alloy steel and fully heat treated for maximum strength.
Nuts are .150″ taller than stock to prevent the nut from bottoming out on the stud when the head has been milled.

Studs are the preferred fastener choice for high performance engines. Unlike a bolt, a stud uses all of the threads in the case, and it doesn't have to be removed during disassembly which adds wear on the case threads. Studs don't twist like bolts when being torqued down, so torque readings are more accurate.
