FAQ
- What does DIN 571 mean? DIN 571 is a German industrial standard that defines the dimensions and mechanical requirements for hexagonal head wood screws, ensuring compatibility and reliability across applications.
- Is the zinc plating suitable for outdoor use? The zinc coating provides moderate corrosion resistance, making these screws suitable for covered outdoor environments, though stainless steel is recommended for fully exposed conditions.
- Do I need to pre-drill before installing these screws? Pre-drilling a pilot hole is recommended, especially in hardwood, to prevent splitting and to ease installation.
- What tool is required to drive these screws? A wrench or socket driver sized to fit the hexagonal head is required. No screwdriver bit is needed.
- What is the pack size? Each pack contains 100 lag screws, making it practical for professional or high-volume construction projects.
