If you’re fastening a ledger board to a home’s rim joist, you need structural screws designed for ledger applications. This guide highlights five top options that balance strength, installation speed, and corrosion resistance. It’s ideal for professional builders and serious DIYers who want code-compliant, durable connections. The products below are selected for varying project sizes—from single-family decks to multi-story builds. Review the features, best-use scenarios, and any limitations to pick the right fastener for your ledger connections.
| Product | Best For | Notes |

| FastenMaster LedgerLOK FMLL005-50 (5″) | Code-compliant ledger installations | Built-in washer head; easy inspection |
| FastenMaster LedgerLOK FMLL358-50 (3-5/8″) | Smaller packs for quick projects | Code ESR #1078; integrated washerless design |
| CAMO Ledger + Multi-Ply (5″) | Low-friction drives; all-in-one kit | Includes bit; Type 17 point |
Power Pro LedgerTite Structural Screws (5/16″ x 3-5/8″)
Best for: Ledger-to-rim-joist connections in standard deck projects. These LedgerTite screws are engineered for ledger-board applications, aiming to provide superior holding power with faster driving versus traditional lag screws. The diamond shank design reduces drive friction, which can save battery life during installation. The multi-layer epoxy coating supports exterior use with treated lumber. A possible limitation is that installation may require a pilot hole in some wood species, depending on local code expectations.
Why choose this
- Engineered specifically for ledger boards
- Diamond shank reduces friction and torque
- Corrosion-resistant coating for outdoor use
Power Pro LedgerTite Structural Screws (5″)
Best for: Thicker ledger assemblies or higher load-bearing decks. The 5-inch LedgerTite screws extend deeper into framing, enhancing pullout resistance and load distribution. Features mirror the 3-5/8″ variant with the same diamond shank and corrosion protection. The main trade-off is longer installation time in tight spaces, which may matter on smaller job sites.
FastenMaster LedgerLOK FMLL358-50 (3-5/8″)
Best for: Code-compliant ledger installations with a compact pack for smaller projects or retrofit work. This LedgerLOK variant is nationally code compliant (ESR #1078) and features a built-in washer-like design that eliminates the need for extra washers. It’s well suited for straightforward ledger connections where inspectors require visible fasteners. A limitation is that some installations may benefit from a predrilled pilot in dense wood or composite substrates.
FastenMaster LedgerLOK FMLL005B-250 (5″)
Best for: Larger ledger installations or ongoing deck-building projects requiring bulk fasteners. This 250-count pack reduces stopping to reorder. Built-in washer head improves time-to-inspection readiness, and the larger hex head can enhance bit engagement. Choose this if you’re deploying multiple ledger connections in exterior framing. A potential limitation is storage space when unused stock rises during off-season work.
CAMO Ledger + Multi-Ply Flat Head (5″ x 5/16″)
Best for: Decks that prioritize smooth driving and reduced cam-out. The Type 17 slash point helps pre-drill less material, and the T-40 star drive reduces cam-outs during installation. The kit includes a bit in every package, which simplifies tool compatibility. A caveat is that bundled bits may wear if used with harder wood species, necessitating occasional bit checks.
Buying Guide: Ledger Board Structural Screws You Should Consider
- Code compliance and listings: Look for ESR numbers or ICC certifications indicating suitability for ledger connections in exterior, treated lumber, or coastal environments.
- Thread design and shank: Diamond or optimized thread patterns reduce drive friction and torque. A knurled or knurled-like shank lowers driving resistance, improving efficiency with power tools.
- Coating and corrosion resistance: Exterior ledger connections benefit from multi-layer epoxy or similar coatings to withstand weather and salt exposure.
- Head design and washers: Integrated washers or built-in washer heads can simplify inspection and reduce the need for additional fasteners. Ensure the head size suits the bit you use and avoids over-driving.
- Pack size and project scope: For large decks, bulk packs lower reordering risk; for small repairs, smaller packs minimize waste and storage needs.
- Installation considerations: Some screws are designed for faster driving with less predrilling; others may require pilot holes in dense or treated lumber.
- Compatibility: Ensure driver bit type (Star/Torque), length, and diameter match your ledger thickness and rim-joist framing.
Frequently Asked Questions
- What is a ledger board in deck construction? A ledger board is a structural member attached to the house framing that supports deck joists and distributes loads to the building structure.
- Which screw type is best for ledger boards? Structural ledger screws with engineered threads, corrosion resistance, and proper length for ledger-to-joist connections are preferred for reliable performance.
- Do I need a washer with ledger screws? Many ledger screws come with built-in washer heads or are designed to work with compatible washers for code compliance and load distribution.
- How long should ledger screws be? Length depends on ledger thickness and joist attachment; typical lengths range from 3-1/2″ to 5″ or longer for robust connections.
- Can I reuse old ledger hardware? Reuse is not advised for structural ledger connections because fasteners can lose strength after removal and reinstallation.
- Are bulk packs worth it for a small project? Bulk packs save time on larger builds and ensure consistent fastener type and size, but may be unnecessary for a single-story deck.
