Do these sleeves work on steel post

Hi CR13 is not suitable for steel posts. It's used on wood posts. You could use CR91, which is customized protective sleeves for steel posts. Please connect with us if you need them and I will notify you when it's available. Thank you.

will these fit tighlty in a 5/16 hole?

The head diameter of this protective sleeves is 11/32". It is not recommended for 5/16" holes. It is recommended that you use protective sleeves CR88, and its head diameter is 15/32 ". You could search Muzata CR88 on Amazon. Hoping this would be helpful for you.

Why I can’t have them anymore within two days?

A good but not perfect product

The protectors were fundamentally good, though there were some minor manufacturing flaws on some of them -- rough corners here an there, but I was able to use all of them. For the price they were quite worthwhile and I'd buy them again.

Nice bits of kit

Ended up not needing them for my particular install but they seemed to be well made, everything else from the brand that I did use was incredible! These in particular are so cheap you can't go wrong on value for the price. No adhesion, it's metal sillies. Looks very easy to install and use.
