How Ledgerlok Screws are Better than Lag Screws Ledgerlok screw is the first wooden screw, specially designed to attach a deck ledger board to the rim stud of a house and not to mention, it requires no pre-drilling like normal lag screws Ledger locks vs lag bolts. And that's the key: Because the structural screw has a smaller shank diameter compared with a 1/2-inch-diameter lag screw, the same load is. Some have mandated the use of LedgerLok over lag screws in their county code. A timber locks head is so small it can pull straight through the material
It is a code-approved deck ledger board fastener that replaces lag screws and through-bolts. Its triple-coating makes it corrosion resistant and perfect to use with pressure treated lumber. LedgerLOK's built-in washer head eliminates the need for an additional washer, saving time and money. It's super-sized threads give superior holding power . You will usually need the length of the bolt to be at least 4- 6 to penetrate through the 2x ledger board, the house sheathing and into the solid house rim. Never counter sink bolts
Table R502.2.2.1. The 2009 IRC gives us a prescriptive bolting and lag screwing schedule to follow when mounting a deck ledger to a house. Table R502.2.2.1 has three options: ½ in. bolt, ½ in. lag screw and ½ in. bolt with the ledger spaced off the wall sheathing by ½ in. for those who like the flow-through design Lag bolts, on the other hand, have a hexagonal head that requires socket wrench for fastening. Because they are quite thick, they require a pilot hole to be pre-drilled. As such, structural screws are much easier to use. Because they don't need pilot holes, they can be used in roughly half the time compared to lag bolts Lag Bolts Used for Deck Construction. For lag bolted deck connections, drill a full-diameter pilot hole for the unthreaded portion and a smaller hole (65 to 75% of the lag's diameter) for the threaded portion. So, for example, a 1/2-inch lag would get a 5/16-inch pilot hole for the threaded portion; a 3/8-inch diameter lag would get a 1/4. Three #14 flat head stainless screws 4 long per stud.

A lag screw also requires a clearance hole through the ledger (in the same size range as for a 1/2-inch-diameter bolt), plus a smaller pilot hole through the house rim joist and wall sheathing. The pilot hole should be the same diameter as the root of the screw portion of the lag, generally 5/16-inch diameter For screws, an impact driver will work just fine. For bolts, as Ecnerwal points out, you need to drill pilots, so there's really no need for an impact wrench for that, either. UPDATE: xster makes a good point that we should probably agree on terms first. The traditional lag bolt is, technically, not not a bolt at all, but a screw • Dimensions for Lag Screws in NDS Appendix L • Wood screws, Nails/Spikes • Tip length, E = 2D • Bearing length = penetration -E/2 • 6D minimum penetration for nails*, spikes, wood screws • 4D minimum penetration for lag screws *Exception for double shear connections with clinched nails, D ≤ 0.148 2
Secondly, he said if one is really concerned to lag bolt 2x4 flat against the wall to the floor to support the ledger. Oddly enough I found that the lateral load value on a 5/16 lag screw is not appreciably less than a 1/2 lag bolt (220 vs 290 for 4 lag penetration in main member). Thanks, Ji 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 Install two bolts at the end of each ledger board.
