The KMC Z1eHX is a heavy duty single speed or fixed gear chain in 3/32" or 1/8".

It features high pin power with reinforced durability, stretch proof treatment with a heavy duty structure, mushroomed riveting

This is an e-bike rated chain (thus the "e" in the name), but don't let that discourage you. E-rated just means it is tough enough to withstand the forces and wear of an e-bike, but it works just fine as a long-lasting single speed or fixed chain.
