New connecting rod bolt locking pal nut for early chain driven "Go Devil" motors. For 7/16" diameter bolts only. Secures together nut and bolt for proper torque.
Questions: About to renew my pistons and conrods on my GPW but how do you use or fit these PAL nuts as my old set don't have them fitted?
They just slide over the bolt/nut to lock it in once tightened.
