Hex bolts are bolt fasteners with six-sided hexagon heads and externally threaded bodies. Hexagonal head profiles allow easy wrenching while putting enough torque into the bolting joint. These bolts are used with hex nuts or tapped holes. Hexagon head bolts, hex machine bolts are another alias for hex bolts. Hex bolt dimensions are defined in both metric and imperials sizes with unified national coarse pitch, fine pitch, fixed pitch, and metric head profile. These are produced across all material categories and ASTM specifications. Hex bolts are used in oil& gas, petrochemical industries, waterline flanged connections, Electrical transmission towers and can be seen in our everyday life.
The Hex bolt comes under the Bolts & Cap Screws category ANSI / ASME. A large fastener head is required to distribute the clamping loop with hex bolts and hex cap screws. These attachments are used at high temperatures and testing. The cap screws have a washer under the head. These are used in the appropriate operation. A cap screw refers to a complete threaded bolt connection, while a bolt is an equivalent component threaded. An exterior threaded attachment with a hex head trimmed, but no washer faces on the bearing surface. The hex cap screw does not have the same body tolerances as the hex cap. These are used in various general-purpose applications in situations where dimensional tolerances are not as necessary depending on the grade.
Applications and Uses of Hex Bolts:
Their main use of hex bolts is for heavy-duty applications including:
Engineering applications
All kinds of construction projects
Pipe lines-Oil, Gas, Water
During the erection, repair, and maintenance of buildings, bridges, and road infrastructure
Machinery assemblies
Vehicle and automobiles industries
Electrical transmission towers
Waterline flanged connections
Turbines, Windmills
Subtypes:
Fully threaded hex bolts
Partial threaded hex bolts
Reduce Shanked hex bolts
Collar hex bolts
Forming:
Hot and cold forging
ASME, BS, DIN, ISO, UNI, DIN-EN, ASTM, and all International Standards
The bolt material you choose depends on the type of project. If you need to use bolts outside where they may be exposed to weather, you should use corrosion-resistant material, like steel or titanium. You should select bolt material depending on the weight of the item you’re bolting and the conditions around. Any bolts used near plumbing fixtures or in rooms where they may be exposed to humidity should be selected for water resistance. Hardened or tempered steel creates the strongest bolts. If you’re using hex bolts to secure something that’s going to support a lot of weight, you should get the strongest bolts available.
