In the game manual, Rule <R5> c 18 says all mechanical fasteners (nut, bolt, screw, etc.) of any length, any thread type, up to 3/8 in. diameters are allowed.

However, it also says the intend of the rule was to allow teams to use fasteners similar to TETRIX ones from local stores.

Currently my team is not registered so we can't post questions on the forum but can someone post the following questions on the official FTC forum?

1. Sheet metal screws, hex bolts, lock washers are not in the TETRIX kit but the rule <R5> c 18 says ANY mechanical fasteners are allowed, so are they legal for FTC?

2. Are 6-32 thread lock-nuts allowed?

3. Are 6-32 thread socket head cap screws longer than the ones in the TETRIX kit allowed? Longer as in 2 in, 3 in, etc.

4. Our team bought 1/16 in. aluminum square tubes from a local store and the decimal equivalent of 1/16 in. is 0.0625 in. However, on the receipt it round the decimal places up and it's written as 0.063 in, which exceeds the thickness limit. Would the receipt be a valid proof of thickness since it's a systematic issue, not the actual thickness?

Thanks in advance. My team and I would certainly appreciate it if anyone post these questions on the forum for us.

Also, what do YOU / YOUR TEAM think about the new rules lifting maximum constraints on custom materials?
