LedgerLok Ledger Hex Head Board Fastener
What It Is
FastenMaster 3‑5/8" LedgerLok Structural Wood Screws 50 ct. and similar LedgerLok fasteners are structural wood screws specifically engineered to attach a deck ledger board to a house’s rim joist or band board. They are designed as a modern replacement for traditional lag screws or through-bolts in deck construction.
How They’re Different from Lag Screws
- No pre-drilling required: LedgerLok screws are engineered to be driven directly in without a pilot hole, speeding up installation.
- Built-in washer head: Many versions have an integrated washer-style head, eliminating the need for a separate washer, saving time and simplifying installation.
- Structural strength: Engineered for heavy loads — they provide a secure connection comparable to, or better than, ½″ lag screws when properly installed.
- Corrosion resistance: Often coated with a proprietary multi-step finish that resists corrosion and is suitable for pressure-treated lumber and outdoor environments.
Features & Benefits
- Code-compliant: Designed and tested to meet current deck construction standards for ledger attachment.
- Faster install: No two-step drilling and washer placement — just drive with a compatible impact driver.
- Strong holding power: Large threads and robust construction deliver a strong shear and tensile strength for structural reliability.
- Multiple sizes: Available in various lengths (e.g., 3-5/8″ for standard ledgers, 5″ for deeper penetration) to suit different framing conditions and material thicknesses.
Typical Uses
- Attaching deck ledger boards to rim joists on houses or structures.
- Securing heavy lumber connections where structural strength and code compliance are required.
- Can be used in treated lumber, engineered lumber, and similar framing materials.
