WanyifaTitanium Ti DIN912 M4x15mm Tapered Head Hex Bolts M4 15L Bicycle Screws Pack of 10

One bolt stripped and one snapped into two under less than 5 Nm of torque when I was tightening with a torque wrench. Luckily I only needed 6.

I'm very pleased with these bolts.If you plan to install a water bottle cage and tire pump mount together in the same location, you should probably consider longer 18mm bolts, shown here: https://www.amazon.com/gp/product/B06XHGXCC8/ref=ox_sc_act_title_1?smid=A2I1NUQAVI583F&psc=1
