In 6mmx0.75 thread for a ZG47.

I have a drop box SunnyHill bottom metal.

I've tried NECG and Sunnyhill. I have a note into Forester.

Blanks would be fine as well (I've asked the three above that question as well)

Thanks!

Can you modify one of these.

that's my backup plan - socket head screw.

Just whip them out on your lathe.

Therein lies the problem - no lathe! I have a friend I'm going to ask to see if he will turn some.

Call your local community college and see if they have a machine shop program. They could turn them for practical experience. Being in Austin this might be a stretch but who knows. Might have to tell then they are for your electric lawn mower or other stupid project.

Good idea

Assume you only need the front screw? If so, I've ot a bunch...oversized and higher head for custom application 4130 alloy

Here is the process I used to make socket (hex) head action screws sized M6-0.75 for my CZ 550 Magnum actioned rifles.

Kind of time-consuming but it was the best I could do after scouring the market for the right sized screws and coming up empty.

Start with Brownells 1/4 inch diameter socket head long blank screws.

Then shorten and convert them to correct length M6 screws with a 0.75 pitch as follows:

• Shorten the rear screw to 41.6 mm shank length and the front screw to 24.8 mm. Your lengths may vary.
  
  
• Turn down the head to around 9.9 mm diameter. Box stock height of the head is fine.
  
  
• Turn down the portion of the shank at the end of the screw to 0.234-0.236 inch diameter.
  
  
• Use an M6-0.75 die to thread the screws.

Only about 10.5 mm of the end of the shank needs threading.

I did the turning on an old Unimat mini-lathe. Great tool for this kind of job.

I've got some left over blank screws if you want or need any.

Good luck!

Spot on as always, just need the front. Will send pm

Socket heads are a nightmare IMO, Torx is the only way to go or is better option anyway. otherwise give me a slotted head and a fitted screw driver.
