Yes, the SM-SH51 cleats are compatible with virtually all Shimano SPD pedals, with the sole exception of the M858 model.

The SM-SH51 is a single-release cleat, meaning it only disengages when you twist your heel outward. Multi-release cleats (like the SM-SH56) allow you to release by twisting in multiple directions, which can be helpful for beginners but may lead to accidental un-clipping for more aggressive riders.
