Topic tags/keywords: question

I am shopping for a vise and I see vises with a continuous nut.
What’s that?
(It could be me: I was born nut and I shall die nut.)
My understanding is that a continuous nut is just the normal nut, not quick release but this vise announces that it is both quick release and continuous nut ( so now I am very confused and this drives me nut):

Jorgensen 40709-C

Jorgensen 40709-C
Style No. 40000 Continuous Nut 4” x 7” Professional Woodworker’s Vise

Jorgensen’s 40000 heavy-duty vises are unequaled in quality. ”Quick-Release” action lets you bypass the screw for fast opening and closing. Solid steel dogs in the front jaws, when used in conjunction with a bench stop, allows oversize work to be held securely on the bench

I saw this thread and thought you had found out about my stay at the Hotel with the nice warm coats with sleeves that tie in the back!

But I’m much better now!

Otherwise I have no idea, but I thought I’d bring it to the top again.

I’m no expert, but I’m pretty sure a continuous nut (in a vise) just means there’s no “quick release” or fast adjustment (for example, quarter turn and then slide it against the workpiece, and then tighten down more)

Well usually a continuous nut indicates it is not quick release, but in this case since it is advertised as quick release, I dunno. Two possibilities, one they have some kind of quick release mechanism that doesn’t use a split nut or it is some confused advertising copy hype written by somebody that doesn’t know vises.

Perhaps it has a continuous nut, and the “quick release” does not mean a split (sliding) nut, but some mechanism that disengages the threaded rod piece. Kinda like how bar clamps have the threaded portion to do the tightening, and at the same time has the “quick-release” portion on the bar for coarse adjustments and release.

I have a vise like this. I believe it refers to the “quick release” feature that allows the vise nut to release the screw upon the screw being turned 1/2 turn counterclockwise (unscrew). This lets the vise jaws to be rapidly pulled apart by hand without a lot of unscrewing. When you turn the screw clockwise (screw in), the nut engages the screw after 1/2 turn and begins to tighten the jaws.

I have always heard of this being called a “quick release”. I have never heard of the term “continuous nut”. Truthfully, this type of vise is simple enough that I can’t envision the continuous nut refers to anything else.

The Record style vises have a lever that disengages the partial
nut so the vise can slide. The Jorgensen style vises have
a different sort of mechanism where the nut disengages
in a different way. I suppose the nut goes all the way
around the screw, but it would have some sort of
flair or elongation that allows the threads to disengage
and the rod to slide.

I like the Jorgensen style mechanism better. I have a
Record. I guess the grass is always greener.

Thank you all for your replies.
I have a record clone it works OK but I had another vise that never worked right and I now want to replace it.

I believe the confusion here is caused by a typo in the advertising. 40709 is the quick release version of the vise, and 40709-C is the continuous nut version.

I have this vise (the quick release version) and I love it. Very heavy duty. FYI, when I bought mine Tools Plus had the best price.

Also, most stores carry the 40709 version, 40709-C is harder to find.
