Wife was out shopping last night so I thought Ii could steal some time wrenching on my truck. Went to replace the fuel pump when I came across this type of bolt securing it to the engine. I only have hex sockets, so what do I need to buy now??? Is this a typical bolt used or a P.O.S.T?

I've never seen one like that on either of my II-A's, Bob. I have a couple of star sockets in my toolkit that might fit over that odd nut.
Anyone else ever seen one like Bob's photo?

I've seen tons of them--On F-18 fighter-jets. It's a spline nut. It should come out with a regular 12-point socket. Maybe even a 6-point, but it is designed for a spline wrench or socket. See:Originally posted by Jeff Aronson

That looks like a high strength 12 point shoulder nut or what he said above. I know they are used on the big end studs on the Rover V8 at least but it's been so long since I opened up my 2 1/4 that I can't remember what's used on it. My bet is that someone dipped his hand into the jar of fasteners and chose the fancy nut by chance.Comment

i've just completed a rebuild of my 2.25 and there ain't no nuts like that anywhere on it. the fuel pump is secure with 2 studs 5/16-24 about 1 1/4" long and 2 5/16-24 nuts that go on with 1/2" socket/wrench. the studs have 1/2" of thread on one end and 3/4" on the other. the shorter end goes into the plate that's bolted to the block'64 Series IIA 88 Canvas Tilt

that was it! Jeff's mention of "star" socket got me thinking so when I went home for lunch I rummaged around some of my old tool chests (I frequent a lot of flea markets) and found a 12-point 1/2 socket that fit it exactly. Before this I never really knew why those sockets exsisted except to strip Hex-heads. Best believe those won't be re-used.

I love those damn things! I'd put em all over if I had enough to go around.
I also like the 5 pointed (pentagonal) nuts. You ever see those?61 II 109" Pickup (Restomod, 350 small block, TR4050)

12 points are about the only thing GM ever came out with that made sense. I thought 5 point was only waterworks, or one of those funky gascocks.Originally posted by jp-Comment
