For a bolted sill plate, the code requires a minimum number of anchor bolts per plate piece and a limit on bolt distance from plate ends. Which statement is correct?
a.One bolt per plate is always enough
b.Bolts may be placed only at the exact center
c.End distance does not matter
d.At least two bolts per plate piece, with a bolt located near each end (commonly within 12 inches, but not less than about seven bolt diameters, of each end)
Explanation
Each sill-plate piece must have at least two anchor bolts, with one near each end (typically within 12 inches of the end but not closer than roughly seven bolt diameters), so short pieces cannot pivot or lift free. One bolt, center-only placement, and ignoring end distance all violate the anchorage rules.
