New screws for PU mount

Dear Andrew,

The PU mount on my MN rifle was loose. I discovered that the threads holding the PU side mount to the receiver have been stretched. To tighten side mount, I had to remove the locking screws and turn the main screws in more. Now the location cut in the head of screws for the locking screws is not longer correct. The threads are Whitworth (55 degrees) not metric (60 degrees). Please advise.

Thank you.

Best regards,

Okay. We may have some replacements available in our spare parts bin. There are several fasteners used in that mount so I need to be sure which one you are looking to replace. Can you please take a picture of the mount and the location of the fastener?

Thanks Andrew,

Sorry I have been off line for some time. I will send you pictures. As they say, "A picture is worth a thousand words."

On the topic of Wentworth vs. Metric threads, do you know of any sources to purchase Wentworth taps and/or dies? Thank you again.
