Hello,

If you find the thread type and length you can pretty much customise your nut set. Take the hex bolt out and measure the depth and work out the M number (M = width of the bolt in mm) and fine or coarse thread.

Get a pack of the same M thread bolts from Bunning's and use the headsets from E-bay etc for the tool free toppers. T bar, 5 or 7 star plastic heads.

"Knurled Thumb Nut Aluminum Alloy Hand Grip Knob Bolt" got my vote, insert the bolt with locknut glue and cut to the required length. Really nice finished bolt for less than $4 a pop.

If you need the measurements, I have a GSO spider I removed recently, if I can find the bolts and check I'll post again.

Ps. Going from agena specs, if you use the "Knurled... as above" in Ebay, you can find M5 Bolt cap with 12mm depth and a 20mm head, pack of 5 for $12 posted.
