Excellent service, two of the items I purchased were out of stock but was given fair options on refund, store credit or replacement. I opted for replacement as there was a different version available and one of the items did arrive bent and they sent out

What torque practice is recommended for M2 socket button screws?

Use light to moderate torque and a proper hex driver to avoid head rounding and to maintain thread integrity, especially on plastic mating parts.

Are there preferred washers or spacers to use with this screw?

Flat washers or nylon spacers can distribute load and protect plastic surfaces. Choose washer thickness to preserve necessary thread engagement for safe fastening.

How should I inspect these screws after a race?

Check head condition, ensure threads are undamaged, and confirm the screw still achieves firm clamp. Replace any screw with deformed threads or stripped heads.

Is this screw suitable for repeated assembly and disassembly?

Yes, with correct driver technique and moderate torque it tolerates repeated service. Avoid excessive force to prolong service life.
