End screws shall be located 6" from the end and at 1 1/2" to 2" from the bottom of the ledger. For screws located at least 2" but less than 6" from the end, use 50% of the load per screw and 50% of the table spacing between the end screw and the adjacent screw, and for screws located between 2" and 4" from the end, predrill using a 5/32" drill.

In general, the total length of your lag screw should at least be double the thickness of the material you're using. For example, if your wood is 10-inches thick, your lag screw should be around five inches long or just slightly above that mark."

Step 1 - Measure the Thickness of Your Lumber Materials, You need to check the thickness of your lumber materials in order to get an idea as to the size and length of the lag screws that you need to connect the logs together. To do this, use a ruler to measure the thickness of the log then record the figures on paper.

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

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

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

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.

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.

If you use bolts in place of nails, use 2 3" lag bolts - one on the top and one on the bottom - every 24". Alternatively, you can use 4" carriage bolts at the same spacing. Bolts should be spaced 2" from the edge of the joist to prevent cracking or splitting. Finally, when nailing or bolting - or both - be sure to also use a

My lag bolts are 1 5/16" apart (center to center) or 32.5-33mm. Also, referring to flange placement on the shell, the ledge underneath where the 1 piece flange rests is 9/16" below the tone ring skirt (13mm). Are these standard measurements so I could expect a "Mastertone" pot to fit? Jon, I position my lags as such.

Lag screw tips must penetrate the house rim joist - that's at least ½ in. Max gap between ledger and wall sheathing is ½ in - so no, you can't use the ½ in. bolt with spacer option over the siding unless it's T 1-11. Bolts and screws must be located 2 in. down from top and up from bottom of ledger and staggered up-down.

11.4.1 Lag Screws and Wood Screws When a lag screw or wood screw is subjected to combined lateral and withdrawal loading, as when the fastener is inserted perpendicular to the fiber and the load acts at an angle, α, to the wood surface (see Figure 11F), the adjusted design value shall be determined as follows (see Appendix J): 22 (Wp)Z Z
