Wood Lag Screws – Hex Head

Hayn Wood Lag Screws (Hex Head) are stainless steel hex head lag screws for Deck Toggle Jaw System installations on wood structures, available in three thread sizes from 1/4" through 3/8" and two lengths per size to accommodate varying post thicknesses and deck material depths. 

Strong Where It Matters

Wood Lag Screws - Hex Head

The hex head profile allows installation with a standard wrench or socket driver, making these the practical fastener choice for deck toggle jaw mounting where a screw driver-compatible fastener would be undersized for the load. Short versions (1-1/2" length) suit thinner post material and surface-mount applications; long versions (2-1/2" length) provide additional thread engagement for thicker posts or installations where greater pullout resistance is required. Three thread sizes — 1/4", 5/16", and 3/8" — correspond directly to the Hayn Deck Toggle Jaw System screw size range, making it straightforward to specify the correct lag screw alongside the toggle jaw hardware.

Engineered In America Every Hayn fitting is designed and manufactured at our facility in Rocky Hill, Connecticut — the same American workmanship that has set the standard for stainless steel rigging hardware since 1950.
Cold-Worked Production Hayn fittings are cold-worked, not cast. That distinction matters: the cold-working process refines grain structure, increases fatigue resistance, and produces a fundamentally stronger component — one built to perform when the load comes on it.
Precision Manufacturing Our Rocky Hill production floor runs CNC vertical mills, CNC lathes, large-capacity mill-turn centers, and waterjet cutting systems — all configured to produce hardware that meets exact specifications, every time.
75+ Years of Excellence Hayn has been engineering and manufacturing marine and architectural rigging hardware since 1950. That track record isn't just history, it's the design knowledge, failure data, and continuous improvement that goes into every product we make.
