Product
Zinc-plated steel lag screw conforming to DIN 571 standard, measuring Ø8x110mm, supplied in a convenient pack of 100 pieces for structural and heavy-duty wood fastening applications.
Specifications
- Manufactured from steel with a zinc-plated finish providing corrosion resistance in standard indoor and sheltered outdoor environments
- Compliant with DIN 571 standard, ensuring consistent dimensional accuracy and mechanical performance
- Diameter of 8mm and length of 110mm, offering deep penetration and strong holding power in timber and wooden structures
- Hexagonal head design allows installation with a wrench or socket tool for controlled torque application
- Pack of 100 pieces ensures availability for large-scale or repetitive fastening tasks
Usage
Insert the lag screw directly into pre-drilled pilot holes in wood using a wrench or socket driver. The threaded shank bites into the wood fibers, creating a secure mechanical connection suitable for structural assemblies, framework, decking, and heavy timber joinery.
FAQ
- What is the DIN 571 standard? DIN 571 is a German industrial standard that defines the dimensions, tolerances, and mechanical requirements for hexagonal head wood screws, ensuring interoperability and consistent quality.
- Do I need to pre-drill before installing these lag screws? Yes, pre-drilling a pilot hole is strongly recommended to prevent wood splitting and to facilitate proper installation, especially in hardwoods.
- Are these lag screws suitable for outdoor use? The zinc-plated finish offers moderate corrosion resistance, making them suitable for sheltered outdoor environments, though stainless steel alternatives are preferable for fully exposed conditions.
- What tool is required to drive these screws? A wrench or socket driver sized to fit the hexagonal head is required. An impact wrench can also be used for faster installation.
- What is the recommended application for Ø8x110mm lag screws? This size is well suited for structural timber connections, heavy-duty wood framing, decking substructures, and securing large wooden components where high pull-out resistance is needed.
