Frequently Asked Questions | FAQ
What size spanner do I need for an M6 nut?
A standard hexagon M6 nut or bolt head typically requires a 10mm spanner or socket. Always verify the specific head type of your fastener, as some specialized bolts (like roofing bolts) may use screwdriver slots instead.
What is the clearance hole size for an M6 bolt?
To allow an M6 bolt to pass through a material freely, you should drill a clearance hole of 6.5mm or 7mm. This provides enough room for the 6mm shank to fit without binding while ensuring the head and washer still grip the surface securely.
What is the difference between an M6 bolt and an M6 set screw?
In trade terms, an M6 bolt typically features a plain, unthreaded section of the shank under the head, whereas an M6 set screw is fully threaded all the way to the head. Set screws are often preferred when fastening into a tapped hole or when maximum thread engagement is needed.
