Speaker Spike Help


Looking for assistance with two issues related to a rear spike for my specific speaker application.

A.  Recommendations for a spike (DOES NOT have to end in a sharp point) of the following size:

--- 0.375 to 0.875 inches (~10mm to ~22mm)
--- 1 inch / ~25mm maximum diameter / width
--- flat top OR with threads


I'm currently using the Eden Sound Hemi-Spike (extra large, flat top, brass):

B. What do you recommend for securely attaching a flat top spike (the Hemi-Spike has a 1 inch / ~25 mm diameter) to the speaker cabinet bottom?

At present, I'm using a disc/ pad with double sided adhesive. 


[Note: The flat top, with adhesive, is a first step solution. I fully realize a threaded spike will offer superior coupling]

[Note: I have already considered Star Sound Audio Points]


Thank you very much!

@imhififan  Your suggestion is an option I have not considered. It is an excellent solution. Thank you!!! 
@imhififan ,
Nice suggestion, but I would be a little concerned if the OP's speakers are very heavy(-he/she doesn't mention the model). Using a screw hole to support a heavy object might damage the wood if it encounters any twist or uneven load. That was the reason I was asking if there were threaded inserts.
Seeing how there are holes for the phillips screws, I would just enlarge them and install some threaded inserts, if there is sufficient material available. Gluing those into the cabinet should provide a better fastening option whether he decides to use a threaded spike or add the aluminum bar you suggested.

Yes, if the speakers phillips screws size less than 6mm and without threaded inserts, your recommendation is much better.   
BTW, if using a aluminum bar, lower profile spike will be needed.
