Frequently asked questions

What is the M8 x 40 hex bolt used for?

The M8 x 40 hex bolt is a general-purpose 8.8-grade threaded fastener with an 8mm metric thread and a 40mm length. It suits medium-duty mechanical, body and chassis joints that need a bit more grip length than the shorter M8 x 30.

What does the 8.8 grade mean on the M8 x 40 bolt?

On the M8 x 40 hex bolt, the 8.8 property class means medium-carbon steel with a nominal tensile strength near 800 MPa. That gives it the strength for general structural and mechanical fixing duties, well above a basic mild-steel bolt.

How do I know the M8 x 40 is the right length?

Choose the M8 x 40 when the parts you're clamping add up to a moderate thickness, still leaving enough thread to fully engage the nut or tapped hole. At 40mm it sits between the shorter M8 x 30 and the longer M8 x 50 in this range.
