## Description

ANSIEDIO M12 Hex Bolt, 12.9 Grade High Tensile Alloy Steel, Outer Hexagonal Screws for Machinery Industry Fastener, (Fully Threaded) M12×40mm,3 pcs : desertcart.co.uk: DIY & Tools

Review: M12 Bolt - If anyone looking for tread pitch on M12 bolt is 1.75 bolt itself is great 10/10 but not good for what i intended
Review: Used on BMW to replace rear toe arms bolts - On E90 toe arm bolt snapped, have to drill out original 10.9 bolt out and as thread was damaged I have to set bolt and nut setup. So decided for this 12.9 bolt and A2 nut, so far it holds well.
