1/2 in. x 4 in. Hex Head 18-8 SS Lag, Hex
Heavy-Duty Stainless Steel Lag Bolts for Exterior Projects
1/2 in. x 4 in. Hex Head 18-8 Stainless Steel Lag Screws
When your project calls for serious holding power, standard screws may not be enough. These 1/2 in. x 4 in. hex head lag screws are oversized fasteners designed for demanding woodworking, construction, and exterior applications where strength and corrosion resistance matter.
Made from durable 18-8 stainless steel, these lag screws provide excellent resistance to rust and corrosion while delivering the strength needed for heavy-duty fastening. Their specially designed construction offers up to 30% more torque capacity than standard steel lag bolts, helping you tackle challenging applications without redesigning your project around inferior fasteners.
Heavy-Duty 18-8 Stainless Steel Construction
18-8 stainless steel provides a combination of strength, durability, and corrosion resistance that makes these lag screws a dependable choice for interior and exterior projects. They are particularly well suited for applications where fasteners may be exposed to moisture or demanding environmental conditions.
Hex Head for High-Torque Installation
The large hex head provides a solid driving surface for a wrench or socket, making it easier to apply the torque needed to seat these substantial lag screws securely. All 1/2 in. lag screws feature a 3/4 in. hex head.
4 in. Overall Length
The 4 in. overall length provides substantial fastening depth for heavy-duty assemblies and structural woodworking applications. The 4 in. lag screw has a 2-1/2 in. threaded length, leaving an unthreaded section beneath the head for applications where additional clearance is needed.
Ideal for Demanding Projects
- Heavy-duty woodworking and construction projects
- Exterior fastening applications
- Projects requiring increased corrosion resistance
- Applications too demanding for standard #12 screws
- Assemblies requiring high torque capacity
- Projects where durable stainless steel fasteners are preferred
