Short Gig for $30 USD: Locate a very specific item for purchase

I apologies in advance, as I suspect this is a very odd request and job post, but I have had no luck with my own efforts on this and will happily pay someone with more education and skill to assist me, even though it is a one time, short gig.


Need:
• Individual with product procurement experience and/or access to international import data for the USA.
• Locate the exact screw/bolt below for purchase, either locally in USA, or internationally (from a manufacturer or supplier).

Product specifications:
• Material: Stainless steel
• Thread size: M4 (4mm diameter)
• Minimum thread length: 3.75mm
• Minimum total length: 5.24mm
• Head type: Flathead, countersink
• Countersink angle: 120° taper
• Head diameter: 7,6mm
• Drive type: Phillips (cross slot)
• Color/Finish: Natural stainless steel finish
• Minimum order quantity: willing to consider 100 or 200 pieces
• Use: Suitable for general fastening with countersunk requirement. (No specific weight/capacity requirement.)
• TOLERANCE (EXTREMELY IMPORTANT): the above countersink angle and head diameter have VERY STRICT tolerances of ±1%, all other dimension may have ±2% as long as the meet the minimum aspects listed above.
• If international purchase, need DDP terms, and door-to-door shipping to USA (zip code 28031).

Additional details:
• The above item is a small screw that is a component of this item for purchase: ---------- (click "In The Box" link/tab on the page and you will see eight small screws. These are the items needed.)
• I have reached out to the company in the link above and have been informed that they do not sell these screws individually, nor will they provide any additional details on their specifications or alternatives for purchase.
• IMPORTANT, MUST READ: I have attempted to locate this screw domestically and internationally, however two specifications continue to be difficult to find: the taper angle of 120° and the head diameter of 7.6mm. If you are reading this, please include "Tight Tolerance" in your message subject line.
• I've received numerous offers from manufacturers/suppliers offering similar screws but with incorrect taper and/or head diameter.
• Have received numerous offers for custom manufacture, however this cost exceeds my budget.

Compensation:
• Will pay $30 USD via Wise to the first applicant that can locate the item in stock, available, for immediate purchase, verifiable via URL, that demonstrates the Total Cost for the item above, meeting all the necessary details above (quantity, shipping terms, etc.), or supply evidence of the necessary experience to locate it.
• This posting will be immediately closed upon successful completion/hire. If it is still listed, it is open/active.

I may have additional gig work in locating similar manufacturer(s) for additional items, though would prefer to discuss this with an applicant that can demonstrate the above skill and abilities successfully.

Thank you and, most importantly, I appreciate any help you may be able to provide!! (I've spent DAYS trying to find this item.)
