Question !/4-20 action screw?



Log in to see fewer ads
I've seen it mentioned here a few times. What is the general consensus? Would it come too close to the v-block screws and weaken the action or is it O.K.?

I have a 1/4-20 action screw on my KIDD Classic receiver and it works great. I never thought converting it would cause any issues and so far there haven't been any.

Old takedown screw top, new one on bottom-

SO you just drilled it and tapped it? That screw looks very long...

It was done by a gunsmith when he pillared the stock. Looks to be just drilled and tapped. The screw is longer due to the fact that the pillar has the escutcheon built into it and the screw head sits flush with the stock.


Outside and inside of pillar-

Beautiful gun!

1/4-20 sound like a good idea to me unless some one with more knowledge chimes in and tells me otherwise...

I have never seen a problem with the stock 12-24 size thread.

I'm doing a pillar bedding job on a B&C stock the Volq t/d screw is too short and I do want a hex head. A bigger screw will take the same torque with less stress. Quater twenty is comon every where. As long as it does not unduely stress anything, I don't see a down side...

the downside is that 1/4"-20 doesn't fit in factory escutcheons without modifications. If you file the bolts to fit, they don't have much of a shoulder.
Additionally, the heads of standard socket head cap screws are pretty tall.
A low head cap screw is shorter, but they are kind of hard to find without buying in bulk or paying out the nose for shipping.

Since you haven't pillar bedded yet, you can use whatever screw you want as long as you can get someone to make you an escutcheon or escutcheon/pillar combo to match it. For instance, if you wanted to use the Volquartsen screw, just have someone make a custom escutcheon or escutcheon/pillar combo that is deeper (the screw won't be flush with the stock, but it will work just fine). If you want to use a 1/4"-20 screw, you would just have someone make you an escutcheon or escutcheon/pillar combo to match it (I suggest making it out of 1/2" or larger rod).


I can make you an escutcheon or a pillar/escutcheon combo to fit either the Volquartsen or 1/4"-20 bolt. PM me for more info.

1/4 x 20 action screw

Fashners has all the screws you want with all types of heads in SS or steel. They are a fraction of price of aftermarkets.

Try the 3/4 x 3/8 brass pillar (Watts A-683) and use a larger, brass escutcheon from Volquartsen ( call to purchase)at bottom, and being larger and wider, the bevel for screw is good for the 1/4x 20 takedown screw. Much more solid. You can cut off the barb of pillar to match the level of escutcheon. Very easy to do.
The Volquartsen escutcheon is a much better unit than the original, and there are
some on this site who may be making them for sale.

one problem you have is that the Volquartsen screw is shorter than the stock screw (and shorter than the ones from Kidd and Raven Eye).

I haven't done it, but I understand that you can use one of the screws from the v-block. They are supposed to be the same thread, but much longer (you must cut to length).

On a side note, the op said he was going to pillar bed his stock, but didn't mention whether he was going to use a flanged pillar or not. I used a non-flanged escutcheon/pillar combo I made from 1/2" brass round stock and then bedded around it (skim coat of Devcon). I am very happy with how it turned out.

1/4 x 20 action screw

The 1/4 x 20 take down screw, SS or steel, is different lengths at
Fastenals, and you only cut to fit. They have all different sizes for a very fair price.

Hi Guys, thanks for the input and the offers!
I am using a cut down Watts A-683 in a a B&C AJ32 target/varmint stock. I can cut down a screw as well as preform other basic machining. Thanks for the info about the bigger Volquartsen escutcheon!
