Tower bolts are commonly used as fastening hardware for doors, windows, cabinets, furniture and other applications where a simple sliding locking arrangement is required. When these products are manufactured from non-ferrous metals such as brass, aluminium alloy or zinc alloy<\/strong>, their material quality, dimensions, finish and construction become important factors in determining their performance and durability.<\/p>\n IS 204 (Part 2):1992 \u2013 Tower Bolts \u2013 Specification: Part 2 Non-Ferrous Metals<\/strong> specifies requirements for tower bolts made from non-ferrous metals. BIS includes this product under its certification framework, and the current BIS Product Manual provides guidance on raw materials, product grouping, sample requirements, testing equipment and inspection and testing arrangements.<\/p>\n The standard covers both barrel tower bolts and skeleton tower bolts<\/strong>, with different types based on material and construction. BIS’s current compulsory-certification listing includes IS 204 (Part 2):1992 \u2013 Tower Bolts \u2013 Non-ferrous metal<\/strong> under Scheme-I.<\/p>\n A tower bolt is a sliding fastening device generally fitted to a door, window or similar movable panel. The bolt slides into a corresponding keeper or socket to secure the door or panel.<\/p>\n Non-ferrous tower bolts are manufactured using metals that do not have iron as their principal constituent. Common materials covered by the standard include:<\/p>\n These materials can provide suitable corrosion resistance, appearance and service performance when manufactured according to the applicable requirements.<\/p>\n IS 204 (Part 2):1992 covers barrel tower bolts and skeleton tower bolts<\/strong>.<\/p>\n IS 204 (Part 2):1992<\/strong> is titled:<\/p>\n Tower Bolts \u2013 Specification: Part 2 Non-Ferrous Metals<\/strong><\/p>\n The standard lays down requirements for tower bolts made of non-ferrous metals.<\/p>\n It addresses important characteristics including:<\/p>\n The standard is currently listed by BIS under its compulsory certification framework.<\/p>\n The standard covers tower bolts manufactured from non-ferrous metals.<\/p>\n The products are broadly classified into:<\/p>\n These tower bolts have a barrel arrangement through which the bolt slides.<\/p>\n These have an open or skeleton-type plate and associated bolt arrangement.<\/p>\n The current BIS Product Manual identifies Types 1 to 5<\/strong> for barrel tower bolts and Types 6 to 9<\/strong> for skeleton tower bolts.<\/p>\n According to the current BIS grouping guidance:<\/p>\n
