Hobson Metric Fine Hex Flange Bolt, M10 x 25mm

The Hobson metric fine hex flange bolt, no serration has a hex head with a flange under it, which acts as a built-in washer face, and a metric fine pitch thread (Class 8.8, zinc yellow). There are 5 items in M10, lengths 25 to 50mm. Class 8.8 is high tensile, and corresponds to imperial grade 5.

Confirm the pitch before ordering matching nuts or tapped holes. These bolts are "No Serration", so the flange has no serrations. Every item is supplied as a box of 100.

Key specifications

Choosing the right option

Choose the thread form first: the screw and the nut or tapped hole must match in thread form, diameter and pitch. Fine pitch means a finer pitch than the standard coarse thread of the same diameter, so a standard metric nut will not fit. Length is measured from under the head to the end of the screw.
