Cylinder Head Bolt SOHC - 12mm SHANKED - M10x1.25x102 (Fiat X1/9, Strada 1980) - OE NOS

This is a Factory OE 10mm x 1.25x102mm thread head bolt as fitted to 1980 fuel injected Fiat and Bertone X1/9s and Fiat Strada. R10.9 in strength, 17mm head.
These bolts are the "long-side" bolts, and are unique in that they have a 12mm shank directly under the head, narrowing down to 10mm. They were fitted in the first Fiat SOHC FI engines whose cylinder heads were drilled for 12mm bolts, but whose blocks were drilled for 10mm.
Very helpful for fitting and locating a carbureted cylinder head to an FI block.
Very hard to find.
Condition: OE NOS
