Hexagon Socket Head Bolts, commonly known as Socket Head Cap Screws or Allen Bolts, are high-strength precision fasteners designed for applications requiring compact installation and high torque transmission. The cylindrical head with an internal hexagonal socket allows tightening using an Allen key, making these fasteners ideal for installations where conventional hex bolts cannot be used. Manufactured according to DIN 912, ISO 4762, and IS 2269 standards, grade 202, 304, 316 , these bolts provide excellent strength, reliability, and dimensional accuracy. They are widely used in machinery, automotive assemblies, industrial equipment, tooling fixtures, and heavy engineering applications.<\/p><\/div>\t\t\n\t<\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t <\/div>\r\n <\/div>\r\n \t\t\t<\/div>\n\t\t<\/section>\n\t\t <\/div>\r\n <\/div>\r\n \t\t\t<\/div>\n\t\t<\/section>\n\t\t
