What size of bolts for H&R 20mm spacers

[SeanM86]

Got 4 20mm bolt to hub H&R spacers of ebay for bargin price but the seller must have binned the bolts that attach it to the hub.

Can anyone tell me what lenght of short head bolts I need?

Seen these on ebay but want to make sure they are the correct size and lenght.

I tryed standard wheel nuts are about 4mm to long and the bolt head is to big. Any help would be great.

can't remember the length of the fixing bolts, didn't pay them much attention. 24mm would be more than enough though.

Think my standard bolts are 26mm long but they seem about 4mm to long. I see they do the short head bolts m12 x 1.5 and 19mm long. Does anyone have a set of 20mm h&r spacers laying around that could tell me the correct size? I don't want to get the 24mm bolts then have to cut them lol. Then again I don't want the 19mm to be short and shred of while driving..

Here's a pic of my spacers
