Mini action screws

[Kswhitetails]

Anyone tell me what screws I need for the Mini action? I've got the BA, the plastic bottom, the DIP metal, and no action screws. I'd be interested in thread spec and length measurements.

Brownels is pointless, there's nothing but 23 pages of barrelled actions, and chassis. Unless you're interested in buying a howa rifle, their website doesn't want you.

I can call LS in the morning, and probably will. I'd love to try and replace with some allen bolts if possible, but I think the heads would get nowhere close to flush.

Thanks Gents.

IIRC it's a 6mm. I have the measurements posted in this section somewhere as someone else was asking.

Factory bolts are allen socket pan head.

Here is a thread that says 22 mm x 1.0 mm.

Here is your thread Sticks.

From your post Sticks.

“The bolts are a Metric thread, 6x.75. Howa torque specs are 50 in# on the action screws.”

[Sticks]

That is the barrel. Action screws are 6mm x.75mm The lengths I can not find.

ETA - Upon further verification...it's 1.0 thread pitch not the .75.

Sorry for any confusion.

Didn't the barreled action come with screws? It should have.

You should be able to get 6 - 1.0mm stainless steel socket cap screws at Lowes.
Do you need the lengths? I could take mine apart and measure.

Here is what I measured from my mini Howa Grendel.
Rear screw 1.425" x .230" x .400" for 10 threads (36mm x 5.8mm x 1mm/thread)
Front screw 1.058" x .230" x .400" for 10 threads (26mm x 5.8mm x 1mm.thread)

I have a 222 bbl'd action sitting here, waiting on a go gauge to match the 20 Tactical reamer that came in the mail today. Got a couple of Bartlein .200/.204, 1-9tw 5-groove bbl blanks that have been sitting in the bbl rack for a couple of years; the #2 sporter will replace the OEM 222 Rem bbl on this action. The action bolts measure 5.84 mm, so you need to look for 6mm bolts with 1mm threads. Length of these OEM Mini bolts are 1.430" & 1.033". 1500 SA & LA actions, and the Mini all come with pan head T30 bolts. Until I got my metric thread pitch gauge out, I had no idea that the action screws & bbl tenon threads were both 1mm.

flatland1, confirmed!!!

[Kswhitetails]

So, can anyone confirm my deductions here? One M6X1.0x25mm(long, rear) and one M6X1.0x15mm (short front). Length measurements are taken from flat (contact side) of head to the tip of the first thread, usually slightly less than OAL. Only the shaft length of the bolt is measured, thickness of the head is moot.

[bj139]

I measured 36mm and 26mm thread length only, not including head, essentially the same as flatland.
6mm diameter and 1.0mm per thread.
25.4mm/inch is the conversion factor.

These 2 items from Lowes and a grinder should get you where you want to be.

Item # 550581 Model # 884900
Hillman 6mm to 1 x 40mm Allen-Drive Black Phosphate Cap Screws (2-Count)

Item # 550641 Model # 884899
Hillman 6mm to 1 x 30mm Allen-Drive Black Phosphate Cap Screws (2-Count)

Kswhitetails,
I have an extra set of factory action screws that I was going to use while bedding. They are not in perfect shape, but are 100% serviceable. If you want them, they are yours. Simply send me a PM with your address and USPS will take care of the rest.

[Sticks]

There we go. I knew someone would have a set laying around.

Frontier Gear - I used some long bolts or all thread (I can't remember) so I would have plenty of protrusion through the bottom and wrapped the threads with painters tape just under the action until the bolts were the same Dia. as the bore when I seated the action to help keep it centered. Coated the tape and bore with release agent.

Amazing bj, thank you very much! I'll get an order made. I was hesitant to post my numbers, I knew I was wrong, but I couldn't verify as I had done the math away from home and was remembering the lengths 10mm too short. I'll head back over there today to see if I can find these actual item numbers somewhere on their hardware wall before resorting to the internet. I thought I was short, glad you could assist.

FG, you're offer is great. I'll let you know if I can't get this handled without stripping you of your tools. Thanks much my friend.

I will post more as the days go by now quickly. I need to get the action bedded, gain a tiny bit of barrel clearance, and do final assembly and checks. The trigger on mine seems a little loose, and the screw seems like it's the wrong one - it's a countersunk head allen screw, and doesn't fit into the hole?.... If you tighten the trigger down to where it won't wiggle, the safety no longer functions. After an email with Timney, they report they do not make a trigger for the mini...

Ks,
Get a nut or two to put on the screw before grinding to length.
Unscrewing the nut will straighten the threads. Chamfering the end and then unscrewing the nut gives a nice, almost factory taper.
The nut also provides a nice place to clamp the vise grips. A can of water for cooling and you should be GTG.
