Oil plug bolt size

Anyone know the size of that bolt for 15 RS?
The bolt you would undo to drain the oil?
Thank you in advance.

One is an M12 and the other an M14. Both use a 6mm hex drive on late model RS.

Thank you and do you know what approximate length of the bolt is?
It says m12x1.5 but that doesn’t tell me the length.
It’s been so long, I don’t remember... but I wanna replace with hex head bolt.

If you are not planning on using a bolt with a magnet in it like Gold Plugs, you have two options:

1. Take to old ones out and measure them.
2. Use the old machinist rule of thumb. The length should be at least 1.5 times the diameter.

Many use the Gold Plugs and they come specific to the spyder. I use the Dimple Plugs which is another manufacturer. You could also check auto supply stores as they carry a wide assortment of plugs with hex heads....:thumbup:

I have heard the hex plugs tend to strip after so much use, so i decided to switch mine to the Lamonster drain plugs, will change them on my next oil change. :clap::2thumbs:

Thank you for the inputs.
I didn’t want to get magnetic ones.
Napa seems to have enough universal plug for 14m-1.5 with 13m head but not 12m-1.5.
Most are either 12m 1.25 or 1.75.
Would either one cause any problem?
