I need a number of extra bolts for the wheels assembly on my Early Tiger. Mainly the bolts to attach the outer wheels which are M2.5 x 16 Button and M2.5 x 25 slot pan. Can I use A2 Stainless Steel bolts and nuts for this? Will these be strong enough?
Also I have found the bolts heads interfere slightly with the tyres on adjacent wheels when the wheels are rotating.....is this normal?
2025 ARMORTEK KIT SURVEY
Over the last few years we have brought out a whole series of kits as a direct result of your feedback - kits like the Pershing, JagdPanther, Hetzer, Leopard 2A4, and more recently the Sd Kfz 7, 88mm Flak 36 and the upcoming Challenger 2.
So, in keeping with what has become and annual tradition, here is your opportunity to once again influence our future production plans.
We have added in some "guide pricing" next to the names of the models. This is a rough estimate of the price at the current rates.
Thanks in advance for your input and we look forward to the results.

Re: Type of metal for Screws
I can't say if they would be strong enough but given the number of wheels on a Tiger, I can't imagine they would break in normal use unless there was a stone in the tracks, in which case something is going to give anyway and M2.5 bolts are cheaper than track links

Re: Type of metal for Screws
Andy,
A2 is type 304 stainless or commonly 18/8 and should be strong enough for any tank project with the added benefit of corrosion resistance. They will not rust like the steel alloy black oxide screws, so I prefer them in most cases. They will not withstand as much torque as the heat treated alloy steel black oxide screws, so use caution to not over torque the screws. But in general applications 304 or 18/8 screws are fine for these models.
As for the heads rubbing, sometimes the wheels can/will rub bolt heads depending on suspension travel etc. The occasional light contact is generally not a problem. But heavy prolonged contact can cause damage. Sometimes it may be possible to counter sink the head slightly deeper to give more clearance etc. Not sure if this helps your specific issue however.
Best regards,
Bob
