By Timothy Aeppel April 27 (Reuters) - Surging inflation and snarled supply lines have hit U.S. manufacturers like Snap-on Inc SNA.N over the past year, but so far haven't hurt profits. At Snap-on, Pinchuk said he doesn’t see significant relief on inflation and supply snarls coming any time soon. Snap-on has an advantage at a time of shortages, said Pinchuk, because they sell directly to consumers.
