Questions about this product
- What thread sizes and wrench sizes do these bolts use?
- They come in M6 through M16. The hex across flats runs from 10mm on the M6 up to 24mm on the M16, so use a matching wrench or socket. Thread pitch is standard coarse, like 1.25mm on the M8 and 1.75mm on the M12.
- How strong is 10.9 grade alloy steel?
- Grade 10.9 is a high-strength class with tensile strength of at least 1000 MPa and yield of at least 900 MPa. That handles high-stress jobs like suspension parts and machinery frames. The alloy steel resists stripping under heavy clamp load.
- Why does the flange matter on these bolts?
- The built-in flange spreads the load like a washer, so you skip the separate washer step. It also adds vibration resistance, which is why they suit automotive and machinery use. The bearing surface is non-serrated, so it won't chew up softer surfaces.
