Bolt nut , Iran
A bolt and nut is a threaded mechanical fastener used for assembling metal, wood, or plastic components in industrial and structural applications. Bolt diameters typically range from M3 to M100, with thread lengths from 6 to 500 mm. Materials include carbon steel, stainless steel, brass, or aluminum, often heat-treated to achieve tensile strength between 400 and 1200 MPa. Surface coatings such as galvanization, chrome, nickel, or powder coating protect against corrosion and wear.
Structurally, the connection consists of an external bolt thread and an internal nut thread, produced according to ISO, DIN, or ANSI standards. Bolt heads can be hex, slotted, Allen, or Phillips, and nuts are typically paired with metal or spring washers to prevent loosening. Standard safety factors range from 1.5 to 2.5 times the working load. These fasteners are widely used in construction, industrial machinery, pneumatic systems, and engineering projects, allowing quick assembly and disassembly.You can order and buy Bolt nut from Iran by contacting us through whatsaap and email.

Material and Coating of Bolts and Nuts Steel, Galvanized, Stainless Steel
Bolts and nuts vary in mechanical strength and corrosion resistance based on material and coating. Stainless steel bolts and nuts typically 304 or 316 offer high corrosion and temperature resistance, ideal for marine, chemical, and humid environments. Galvanized bolts and nuts, coated with zinc hot-dip or electroplated, provide good rust protection and suit outdoor and industrial settings. Plain steel bolts and nuts have high tensile strength but are vulnerable to moisture without coating, usually used indoors or with paint. Selecting the proper material and coating directly affects connection longevity, safety, and durability.
