DIN 571 Hex Head Stainless Steel Self Tapping Wood Screws Blue White

Steel Hex Head Screws for Wood

These steel screws have corrosion-resistant finishes. 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. Length is measured from under the head.

Black-oxide steel screws have a coating that protects the steel from rusting in dry environments and blends in with dark surfaces.

Zinc-plated steel screws resist corrosion in wet environments.

Hot-dipped galvanized steel screws have a thick coating for better corrosion resistance than zinc-plated steel screws. They're a good choice for ACQ-treated (arsenic-free) lumber.
