To determine the size hole needed for a bolt, measure the bolt’s diameter with a caliper or ruler. The hole size should accommodate the bolt diameter for a snug fit. For example, a 1/4-inch bolt needs a 1/4-inch hole. For softer materials, a slightly larger hole may be necessary to avoid damage during insertion. Always refer to specific project requirements for precise measurements.
