FAQS on expansion bolt sizes in mm

Q: What are the standard expansion bolt sizes available in mm?

A: Common expansion bolt sizes in mm range from M6 (6mm diameter) to M20 (20mm diameter). Lengths typically vary between 30mm to 300mm, depending on the application. Always check manufacturer specifications for exact dimensions.

Q: How do expansion anchor bolt sizes differ from regular bolts?

A: Expansion anchor bolts have sleeves or wedges for gripping materials like concrete. Sizes often start at M8 (8mm diameter) and go up to M24 (24mm diameter). Their lengths are longer to accommodate expansion mechanisms.

Q: What size expansion bolt should I use for concrete walls?

A: For light-duty concrete applications, M6 to M10 bolts (6mm–10mm diameter) are common. Heavy-duty loads may require M12 to M20 bolts. Ensure bolt length is 2-3 times the anchor depth for stability.

Q: Are expansion bolt sizes standardized globally?

A: While metric sizes (e.g., M6, M8) are widely used, dimensions may vary slightly by region or brand. ISO 898-1 and DIN 7990 provide general guidelines. Always verify local standards for critical projects.

Q: Can I find expansion bolts in non-standard sizes like 12mm or 14mm?

A: Yes, many manufacturers offer intermediate sizes such as M12 (12mm) and M14 (14mm). These are ideal for balancing strength and material thickness. Custom sizes may also be available for specialized needs.
