I have been exploring a suitable source for more accurate fasteners for the inner hubs of Tigers with resilient (steel) wheels. As I have described on my F01 thread, a better scale look can be obtained with M2.5 hex bolts. This can be enhanced if 3.5mm A/F nuts are used as supplied by Knupfer. Standard M2.5 fasteners longer than 20mm are not available and so a custom solution is required. One size smaller 7BA part threaded bolts at 30mm with one size smaller nuts are available from BA Bolts which may suffice if building the hubs as per the instructions. If however you need a little extra length or wish to add detail at the back of the wheel, perhaps to shield the bearing, then you are stumped.
With this in mind, and to progress my build, I have obtained a quotation for the fastener design shown in the attached drawing. As you can see the bolt is deliberately over length to allow for a range of hub designs. The bolts can be easily cut to length using a tool such as Knipex 97 32 240.. The inner hub requires 15 fasteners and so an upgrade set would consist of 125 bolts (120 + 5 spare) . Full disclosure here... due to my hub design I only need 72 (say 75) bolts and therefore would be prepared to over order and offer them at cost (plus VAT, P&P). The quotation I have from ACCU is as follows:
200 off (so enough for 1 set) at £1.59 each = £198.75 per set
500 off (enough for 3 sets) at £0.92 each = £115.00 per set (would probably order 600 to give 4 sets which may be a little cheaper)
1000 off (enough for 7 sets) at £0.66 each = £82.50 per set (would probably order 1100 to give 8 sets which may be a little cheaper)
I previously asked ACCU to quote just for my requirements... this was prohibitively expensive and so I did not go ahead. The cost to you will depend on the level of interest and the size of the order...

Is anyone interested ? If so respond by PM, thanks.
