Product Description
M12 x 1.5 Metric Fine 10.9 Grade Self Colour Hexagon Flange Bolts
These M12 x 1.5 metric-fine hexagon flange bolts are manufactured from high-tensile property class 10.9 steel and supplied with a self-colour, unplated finish. The integral flange provides a broader bearing surface beneath the head, while the partially threaded body provides a 15mm plain shank.
The live product selector currently offers the M12 x 1.5 x 45mm size. It has a 30mm threaded portion and a 15mm unthreaded shank.

Thread Compatibility
M12 metric coarse thread normally has a 1.75mm pitch. This product has an M12 x 1.5mm fine thread and is not interchangeable with M12 coarse-thread nuts or tapped holes. Always confirm the required pitch before ordering.
The stated bolt length is measured from the bearing face beneath the flange to the end of the bolt. The flange and head are not included in the nominal length.
Property Class 10.9
Suitability for safety-critical or highly loaded applications should be confirmed against the equipment manufacturer's requirements and any necessary material or product certification.
Self Colour Finish
Self colour means the steel is supplied without a protective zinc-plated or galvanised coating. The surface can vary in shade and may contain traces of manufacturing or storage oil.
Unplated steel can corrode when exposed to moisture. Suitable protective oil, coating or controlled storage should be considered where corrosion resistance is required.
