Frequently Asked Questions | FAQ
What size spanner do I need for an M12 nut?
A standard M12 hexagon nut or bolt head typically requires a 19mm spanner or socket. Always double-check your fixings, as some specialized or non-standard bolts may vary slightly.
What size hole do I drill for an M12 bolt?
For a standard clearance fit that allows the bolt to pass through easily without binding, drill a hole of 13mm or 14mm. This provides enough tolerance for alignment while ensuring the head and washer still have a solid bearing surface.
Can I use M12 bolts for structural work?
Yes, but you must select the correct grade. For structural applications, ensure you use high tensile bolts (typically grade 8.8 or higher) rather than standard mild steel. Always check the grade stamped on the head and consult structural engineer specifications for critical loads.
