Per my reply to your first thread under Other Gear, I was not able to find this M8 x 37mm wing bolt in stock from any Sonor Dealer or from any hardware or fastener supplier... and that included North America, Europe and Asia.
I have been restoring drum kits since the ‘70s and have 35+ years experience in electronic & mechanical system engineering so I can humbly reassure you that I’m very resourceful
and believe your best two options are:
1. Order Sonor part # 145 941 81 from your preferred Sonor dealer. If you don’t have one, stdrums in Germany is very good at ordering Sonor small parts with very reasonable prices including shipping. Contact Gerd at

2. Buy a used mount on eBay or similar. This option may require a wait, but low cost deals do appear. And you do -not- need to replace the entire mount on your bass drum... just:
A. Unscrew the wing bolt from the used mount.
B. Turn your bass drum upside down so the receiving nut falls into place behind the bolt hole, and then screw in the used wing bolt.
I have also replaced several of these mounts and the three bolt sleeves do fit tightly into the bass drum holes. If you do decide to go this route, just let me know and I’ll be happy to provide some tips.
BTW, please keep in mind this bass drum tom mount was -not- used on the Force 3000 series... that model was different. This one was used on the Force x001 - x007 series so it is important to reference it to the 3003 or even 3001-3007 series rather 3000 when you talk to suppliers.
Best of luck!
EDIT: The above options presume you are looking for an original or near-original replacement and don’t wish to use an alternate bolt head type as suggested in my other reply.
