The bolts or lags must be placed along the ledger in two rows—one row along the top and one along the bottom—with the fasteners staggered between the two rows at the spacing indicated by the IRC table. For example, on a deck with a joist span of 15 feet, the lag screws are spaced 11 inches apart. To start the pattern, the first lag is

Did the contractor install the lag screws at the correct spacing? This question is answered by measuring the joist span and using the IRC Table 507.9.1.3(1) ledger connection table to select the required screw spacing, or the similar diagram in AWC's DCA 6. For example, for a joist span of 14 ft., the table shown in Figure 1 above

Select screw type and spacing. Example: A 2x Southern Pine deck ledger attached to a 2x Douglas Fir Larch rim joist. Deck joist span 10 feet supporting a 40 psf live load. 1. Live load = 40 psf 2. Joist span = 10 ft 3. Enter Table 1. 4. . Use a 5/16"x 4" RSS at 10" on center. 5.

Stock up on lag screws on Amazon. Drill a hole into the material that is smaller than the diameter of the lag screw. The smaller the pilot hole, the more effective the lag screw will be. You also do not have to go very deep. A good rule is to drill your pilot hole a third of the length of the screw. 2.

Fastener spacing for 4 fasteners is based on tested loads. The design values use the lesser of a 1/8 deflection or a factor of safety equivalent to or greater than that of the code compliant lag screw application. 11. Fastener spacing for 5 fasteners is based on previously published reference lateral design values.

The condition below applies for lag bolts in tension into a 2x narrow face and table 12.5.1E calls out for 1.5 times the fastener diameter for minimum edge distance and 4 times the fastener diameter for minimum end distance. In this case our ½" diameter lag screw requires ¾" edge distance and both can be used.

Lag screws require a pilot hole since they're not self-tapping or self-drilling. This is a two-step pilot hole: step one prepares for installing the shaft's threaded portion, while step 2 makes room for the unthreaded portion. As mentioned in a previous article, hexagonal heads are used when the application requires a high torque value.

Connection Calculator. Provides users with a web-based approach to calculating capacities for single bolts, nails, lag screws, and wood screws per the NDS. Both lateral (single and

However, the proprietary screw spacing will generally be closer for a given span than the code table for 1⁄2-inch-diam - eter bolts or lag screws, so you do need to refer to the manufacturer's informa-tion.
