18-8 Stainless Steel Hex Head Screws for Wood
18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. Also known as lag bolts, they have a hex head for a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. They may be mildly magnetic. Length is measured from under the head.

Super-Corrosion-Resistant 316 Stainless Steel Hex Head Screws for Wood
More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water and are a good choice for ACQ-treated (arsenic-free) lumber. Also known as lag bolts, they have a hex head for a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. They may be mildly magnetic. Length is measured from under the head.

Stainless Steel Flanged Hex Head Screws for Wood
These 316 stainless steel screws have excellent resistance to chemicals and salt water and are a good choice for ACQ-treated (arsenic-free) lumber. The flange reduces the risk of crushing material and the hex head provides a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Screws may be mildly magnetic. Head height includes the flange. Length is measured from under the head.

Wood Screw-Style Hangers
Drive these hangers into wood with an adjustable wrench, pliers, or a special driver bit (sold separately). They’re also known as eye lags.
316 stainless steel hangers have excellent resistance to chemicals and salt water. They’re best for corrosive and marine environments.

Stainless Steel Wood Screw Threaded Studs
18-8 stainless steel studs have good chemical resistance and may be mildly magnetic. Also known as hanger bolts, use them to hang, mount, and fasten parts to wood structures. Install with a stud driver or create wrench flats by threading two nuts onto the stud and jamming them together.
