Product details

Bolt is a cylindrical fastener with external threads, which needs to be used in conjunction with nuts to fasten and connect two or more parts with through holes. It is one of the most commonly used basic parts in machinery, construction and other fields.
- **Structural composition**: A typical bolt consists of three parts, namely the head (used to apply tightening force, common shapes include hexagonal head, cylindrical head, countersunk head, etc.), screw (cylindrical part with external threads, which is the core that cooperates with the nut), and rod tail (some bolts have chamfers or steps for guiding installation).
- **Core Categories**:
- According to the force-bearing mode: they are divided into ordinary bolts (fastened by friction) and high-strength bolts (fastened by pre-tightening force and friction, with stronger load-bearing capacity).
- According to the shape of the head: hexagonal head bolts (most commonly used, easy to operate with a wrench), hexagon socket bolts (beautiful after installation, suitable for small space scenes), countersunk head bolts (the head can be embedded in the surface of the part without protruding).
- According to thread type: coarse threaded bolts (high installation efficiency, suitable for general occasions), fine threaded bolts (good self-locking, suitable for vibration or thin-walled parts).
- **Commonly used materials**:
- Ordinary carbon steel: such as Q235 and 4.8 grade bolts, suitable for low stress and non-corrosive environments.
- Alloy steel: such as 40Cr, grade 8.8/grade 10.9 high-strength bolts, suitable for high-stress scenarios (such as engineering machinery, automobile chassis).
- Stainless steel: such as 304 and 316 stainless steel bolts, which are acid and alkali resistant and rust-proof, and are suitable for food machinery, outdoor equipment or humid environments.
- **Core function**: Realize detachable fastening connections, which can stably transmit tension, pressure or torque, and facilitate subsequent equipment maintenance, disassembly and parts replacement.
- **Application fields**: Covering almost all industrial scenarios, such as machinery manufacturing (equipment casings, parts connection), construction engineering (steel structure fixing, pipe installation), automotive industry (engine, chassis component fastening), home appliances (casing, internal parts assembly), daily necessities (furniture, door and window fixing).
- **Usage Precautions**:
- Bolts that match the material and strength level need to be selected according to the force and environment (whether there is corrosion and vibration) to avoid overload breakage.
- The tightening torque needs to be controlled during installation. If it is too loose, it will easily loosen. If it is too tight, it may cause the bolt to break or the parts to deform.
- In a vibrating environment, anti-loosening nuts, anti-loosening sheets or thread glue can be used to prevent bolts from loosening; in corrosive environments, the rust-proof status needs to be checked regularly and replaced if necessary.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
