Types of Lag Screws We Offer

Hex Lag Screw, Plain

Plain lag screws are untreated and suited for indoor or protected environments. Their coarse threads provide strong grip in wood and other softer materials. They are commonly used in construction, framing, and general-purpose fastening where corrosion resistance is not required.

Hex Lag Screw, Zinc CR+3

These zinc clear plated lag screws provide dependable corrosion protection. Their hex head design allows for secure wrench tightening, while coarse threads anchor deeply into wood. They are widely used in furniture, light construction, and maintenance projects.

Hex Lag Screw, HDG

Hot-dip galvanized lag screws are coated with a thick layer of zinc, delivering superior corrosion resistance. They are essential in outdoor projects such as decks, fences, and utility structures. Their robust coating ensures durability even in harsh weather conditions.

Stainless Steel 18-8 Hex Lag Screw

These lag screws are manufactured from stainless steel 18-8, providing excellent corrosion resistance and durability. They are commonly used in marine, outdoor, and chemical environments where fasteners are exposed to moisture. Their hex head design ensures strong fastening into wood and masonry.

Stainless Steel 316 Lag Screw

These lag screws are made from stainless steel 316, the premium choice for coastal and chemical applications. They resist saltwater corrosion and chemical exposure better than 18-8 stainless steel. They are ideal for marine construction, docks, and industrial environments requiring maximum durability.

Stainless Steel A4 316 Lag Screw DIN 571

These metric lag screws, also known as coach screws, are manufactured from stainless steel A4 316 and comply with DIN 571 standards. They provide superior corrosion resistance and tensile strength, making them suitable for international construction projects. Their coarse threads and hex heads ensure secure anchoring into wood and masonry.

Material Options

South Coast Fasteners stocks lag screws in durable materials to meet performance and environmental needs.

Low Carbon Steel

Low carbon steel is used in plain lag screws, offering dependable strength at an economical price. It is suitable for indoor construction and light-duty projects where exposure is minimal. Its machinability allows for consistent threading and reliable fastening.

Hot-Dip Galvanized Steel

Galvanized steel provides enhanced corrosion resistance for outdoor use. Hot-dip galvanizing creates a thick protective layer that extends the service life of lag screws in fencing, decking, and utility structures. This material ensures durability in exposed environments.

Stainless Steel 18-8

Stainless steel 18-8 provides balanced strength and corrosion resistance. It is widely used in outdoor and general-purpose applications, particularly where exposure to moisture is expected. Its versatility makes it a popular choice across industries.

Stainless Steel 316

Stainless steel 316 offers maximum resistance to saltwater and chemicals. It is essential for marine, chemical, and coastal projects where fasteners must withstand harsh conditions. Its superior performance makes it the highest-grade option for lag screws.

Available Finishes

South Coast Fasteners offers lag screws in protective finishes that extend durability and support specific applications.

Plain

Plain lag screws are untreated and suitable for interior use or environments where corrosion resistance is not required. They are practical, cost-effective fasteners for framing and construction.

Zinc Clear CR+3

Zinc clear plating provides moderate corrosion resistance while maintaining a clean metallic appearance. It is a common finish for general construction, furniture assembly, and maintenance projects.

Hot-Dip Galvanized

Hot-dip galvanized finishes deliver long-lasting corrosion protection for outdoor and structural projects. The thick zinc coating prevents rust in fences, decks, and exposed construction. This finish is relied upon in environments with direct weather exposure.
