We are looking to source or manufacture allen keys with specific dimensions. The keys should be at least 200 mm long, with the short arm measuring less than 15 mm. It would be a bonus if a ball end could be added to one end, although this feature is not absolutely necessary. We are open to using standard tool steel for this project. If you could provide additional details regarding pricing, lead times, and any other specifications, that would be greatly appreciated. Looking forward to your response!
