What are the characteristics of articulated bolts

Bolt, High strength bolts, Screw

According to the GB/T798-88 standard, articulated bolts are also known as eye bolts in China; Also known as fisheye bolts abroad, they follow the DIN444 standard. The bolt with refined hole has smooth spherical surface and high thread precision, and the thread specification is M6 to M64. The surface treatment of loose joint bolts includes: Hot-dip galvanization, dip plating, white plating, color plating and other anti-corrosion measures. The factory color of high-strength bolts is boiled black and blue, and the materials are Q235, 45 #, 40Cr, 35CrMoA, stainless steel 304, stainless steel 316, etc. Application items: filtering self rescue device, gas detection instrument, Dust mask, mining raincoat, mining explosive device, application details: Movable bolts are widely used in: low-temperature and high-pressure valves, pressure pipes, fluid engineering, oil drilling equipment, oilfield equipment and other fields, and are often used in valve industry, folding bicycles, children's cars and other disassembly and connection occasions or tools, The connection between the union bolt and the supporting nut is tight, with a wide range of applications. For valve bolts, sealing issues cannot be ignored, as the operation, leakage, dripping, and other phenomena of the valve all come from here. To ensure safe use, it is necessary to ensure the quality of valve bolts.
