Meet the Hillman 3/8 in. x 6 in. Hex Stainless Steel Lag Screw—a rugged, corrosion-resistant fastener designed to secure timber with confidence, indoors or out. Crafted in durable stainless steel, these lag screws deliver lasting strength where moisture or weather would challenge ordinary hardware.
Key features that set this apart:
-
Size and strength: 3/8" diameter, 6" long provides ample bite for thick timbers and sturdy connections.
-
Hex head: A true hex head with a coarse thread offers fast, tool-friendly installation using standard wrenches or drivers; ideal for deck framing, fences, pergolas, and other outdoor woodwork.
-
Stainless steel construction: Exceptional corrosion resistance helps prevent rust and staining, making them suitable for exterior projects and damp interiors.
-
Coarse thread: Engineered to grab quickly into wood, reducing drive time and ensuring a secure hold.
-
25 per box: Convenient boxed packaging for ongoing projects or multiple installations, with consistent quality in every screw.
Where to use:
- Decks and railings — fasten structural members to framing with confidence in moisture-prone environments.
- Fences and garden structures — reliable joints that stand up to weather and soil conditions.
- Timber framing or posts — long, heavy-duty connections that require a sturdy, durable fastener.
- Outdoor furniture, pergolas, and sheds — secure mounting points that resist corrosion over years of use.
Installation tips for best results:
- Pre-drill a pilot hole to minimize wood splitting and to ensure the screw bites cleanly; choose a pilot size appropriate for 3/8" diameter and your wood type.
- Use a compatible driver with a hex bit for steady, controlled driving; avoid over-torquing to prevent snapping the screw or timber.
- Apply a compatible wood sealant or protective finish near the screw line if the assembly will be exposed to the elements for extended periods.
- Check for any required load specifications and ensure the timber and framing dimensions are adequate for the expected load.
