Stainless Steel Hex Head Wood Screws

With coarse threads that dig in, these screws secure posts and beams in outdoor and wet environments. They won't degrade from moisture or chemically treated wood, such as ACQ-treated (arsenic-free) lumber. The hex head's six contact points keep sockets in place to avoid slipping and stripping on the drive. To tighten, use a wrench or six-point hex socket. Also known as lag bolts.

Drill a pilot hole slightly smaller than the screw to prevent splitting. Length is measured from under the head.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

316 Stainless Steel—Superior to 18-8 stainless steel, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.

Steel Hex Head Wood Screws

Often used on posts and beams, the coarse threads on these screws dig in for a firm hold. The hex head's six contact points keep sockets in place to avoid slipping and stripping the drive. To tighten, use a wrench or six-point hex socket. Also known as lag bolts.

Drill a pilot hole slightly smaller than the screw to prevent splitting. Length is measured from under the head.

Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Hot-Dipped Galvanized Steel—Combines the strength of steel with the corrosion resistance of stainless steel. These screws are an economical alternative to 18-8 stainless steel in wet and outdoor environments. You can use them with chemically treated wood, such as ACQ-treated (arsenic-free) lumber, but they won't hold up to salt water.

Stainless Steel Flanged Hex Head Wood Screws

A built-in flange protects surfaces from splitting and pull-through by spreading pressure over a large area. These screws won't rust, so you can use their coarse threads to secure posts and beams outdoors. They also won't degrade from chemically treated wood, such as ACQ-treated (arsenic-free) lumber. The hex head's six contact points keep sockets in place to avoid slipping and stripping the drive. To tighten, use a wrench or six-point hex socket. Also known as lag bolts.

Drill a pilot hole slightly smaller than the screw to prevent splitting. Head height includes the flange. Length is measured from under the flange.

Thread-Mount Studs for Wood

Also known as hanger bolts, use these studs to hang, mount, and fasten parts to wood structures. Install them with a stud driver, or create wrench flats by threading two nuts onto the stud and jamming them together.

Black-Oxide Steel—Typically chosen for their appearance, these studs have a dark, matte coating that creates a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Zinc-Plated Steel—The most common choice for areas with occasional exposure to moisture.

Hot Glue Sticks

When heated, these glue sticks melt and quickly begin to harden. Use them to seal packaging and form other low- to medium-strength bonds. 3M glue sticks work only with 3M glue guns.

Adhesives that take longer to harden are suited for applications that require some repositioning, because the longer open times allow for more adjustment. For high-volume applications, adhesives with a lower viscosity flow faster than other hot-melt adhesives.
