Bolt nut , Iran
A bolt and nut is a threaded mechanical fastener used for assembling metal, wood, or plastic components across various industries. 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 often 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.

Types of Bolts and Nuts
Bolts and nuts are among the most common mechanical fasteners and are categorized by shape, application, and thread type. Hex bolts are used for heavy metal connections and industrial machinery. Self-tapping screws are for soft materials like plastic and wood and do not require nuts. Set screws secure components on shafts. Hex nuts, lock nuts, and flange nuts enhance safety, vibration resistance, and even load distribution. Selecting the right bolt and nut based on material, size, grade, and environmental conditions ensures structural safety and durability.
