and marking

The screws have a thread of 1-8 and a length of 9

The Grade 8 increases its strength against the pressure and has a tensile strength and hardness of 150

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe

Metric Socket Head Cap Screw Black-Oxide Alloy Steel Partial Thread M30 * 3.5 * 160MM, Grade 12.9 [Allen Key] Quantity:Unity The bolts have a threadThis socket head cap screw is 160 mm long and has a M30 * 3. 5 mm thread [partially threaded]. Made of black oxide alloy steel, it offers slight corrosion resistance in dry conditions. The cup point and 12. 9 grade increase its compressive strength and provide a tensile strength and hardness of 170,000 psi Rockwell C39. In addition, it has a shear strength of 102,000 psi. ISO Metric Pitch Coarse threads are an industry standard. These screws are
