Elevator Bolts
Elevator Bolts. Made of zinc-plated steel. Similar to a carriage bolt, but with a larger diameter, lower-profile head. Once installed the head sits almost flush. These bolts have a square notch under the head that is designed to lock into a pre-punched square hole, or to self-lock in wood. This prevents the bolt from spinning when the nut is tightened. NOTE: Most bolts are sold individually, so you can buy the exact quantity you need (even if you only need 1 piece!) No minimums. Quantity discounts available on most items.
