correct valve cover bolts 383 cuda

[cuda joe]

i have all anker bolrs on there now i have read it originally had studs in the corners . did it have the anker bolts at all are they correct if not what did they have

 

[Xcudame]

Studs in the four bottom corners and 8 each 1/4-20 x .50" bolts in the other locations. Six fasteners total per cover

See below picture.

Mega Parts sells a bolt/stud kit.

 

[cuda joe]

thanks does anyone know where the short 1/4 20 anker bolts go

I'm not entirely sure what you have as an anker bolt. Maybe post an image, and we can help you figure where they go.

The fasteners shown in post #3 are the ones you want for the valve cover.

This has nothing to do with the original question but a bolt without a nut is a screw, the book is fundamentally wrong…

 

[pschlosser]

A bolt fastens into a threaded opening, and a screw fastens to unthreaded materials.

Is the bolt/stud info of this thread just for 383 engines?

 

[Xcudame]

383/400/413/426w/440 from 64 to 78. 59-63 the big block heads had only 4 bolts and no studs.

@DetMatt1 you are technically correct. What we call head bolts are actually screws, but it just doesn't sound right calling them head screws after folks calling the head bolts for over 125 years!

 

[DetMatt1]

A bolt fastens into a threaded opening, and a screw fastens to unthreaded materials.

That is incorrect. A screw fastens into a threaded hole while a bolt requires a nut.
Or it would be accurate to say that every threaded fastener on your car that doesn’t have a nut on it is a screw.

these are the bolts or screws i found in the valve cover of a cuda with a 383 . if they aren;t for the valve cover anyone know where they came from thanks

 

[Xcudame]

@cuda joe did you mean to attach a picture?

 

[cuda joe]

yes here they are

 

[Xcudame]

They look like the 8 valve cover bolts (screws) in the middle of the valve covers. Also the oil pan bolts are the same size and most have the same anchor symbol on them!

I had to Google the bolt vs screw definitions... Source

Bolt vs. Screw: Definitions
Let’s begin with a couple of definitions provided by the CBP which are quoted from ANSI-ASME B18.2.1:

• Bolt: A bolt is an externally threaded fastener designed for insertion through the holes in assembled parts, and is normally intended to be tightened or released by torquing a nut.
• Screw: A screw is an externally threaded fastener capable of being inserted into holes in assembled parts, of mating with a preformed internal thread or forming its own thread, and of being tightened or released by torquing the head.

Machine SCREW, cap SCREW, socket headed cap SCREW, wood SCREW, sheet metal SCREW, self tapping SCREW, and nut and bolt….

But we still say "Cylinder Head Bolts" because of habit I guess. "Cylinder Head Screws" just doesn't sound right to me.

Side note, since nuts and bolts get screwed, are they all screws??

A bolt is a screw without a nut.
