DIN444 stainless steel 304 or black oxide carbon steel eye bolts , hole in bolts


Eye bolts, the domestic is also called the hole in the bolt, GB/T798-88 standard;Abroad is also called the fish eye bolts, following DIN444 standards..It divide into stainless steel and carbon steel black oxide with grade 4.8/8.8/10.9. Refined eyelet bolt, spherical surface is bright and clean, thread accuracy is higher, for the M6 thread specification to M64.Eyelet bolt surface treatment: galvanizing, plating, plating white, color plating anticorrosive measures, such as high strength bolt factory color for black hair, cooking material has: Q235, 45 #, 40 cr, 35 crmoa, stainless steel 304 and 316 stainless steel and so on.Application projects: filter type self-rescuer, gas detection instruments, dust mask, ore mining raincoat, blasting device, application details: eyelet bolt is widely used in: low temperature high pressure valves, pressure pipe, fluid engineering, oil drilling equipment, oil field equipment, and other fields, often on the open connection occasions or tools such as the valve industry, folding bicycle, baby carrier, due to the eyelet bolt is convenient to use, fast, and plays a role of connecting fastening nut use of form a complete set, the application range is very wide.Eyelet bolt for valve, sealing problems cannot be ignored, because the phenomenon such as run, drip, drip of the valve from here, the valve must be eyelet bolt for quality assurance, to guarantee the safety of use..

Our company specialized production and manufacturing of all kinds of, all kinds of high pressure, high strength bolt and screw (HG/T20613-2009, HG/T20634-2009, JB/T4707-2000, SH3404-96, GB/T9125-2003, HG/T21573.2-95, GB/T901-88, JB/T2773-1992), at the same time also can provide all kinds of fasteners (such as stainless steel, austenite, martensite and all kinds of alloy steel), can also according to the various standard production (such as the national standard, American standard and ASME standard, English, German standard) and can provide complementary products, such as gasket (plain washers, spring washers, tilting pad) and all kinds of nuts (square, hexagon, octagon).

This eyelet bolt head shape is more special, fine, big head, in front of the machining head must be a threaded rod diameter machining is good, screw diameter is only a little allowance for finish.If to head block forging, then processing department, due to factors such as loading loose to subsequent machining bring certain difficulties, is not conducive to the production.The original blank selection slightly greater than the rod diameter round steel, due to the head in the thermal block forging materials, a block forging deformation than the big, must be secondary deformation to meet production requirements, the first rough pier is adopted, and then block forging process of spherical, then squish forming process.
