Construction bolts are specialized produced fasteners that are integral to constuction project, they are used to join two or more part together, such as railway tunnels, building foundations, bridge construction, etc. They are designed with unique features and for specific applications, making it essential to choose the appropriate type of bolt for each construction project.
Construction Bolt Types
- Hex bolts, characterized by their six-sided head, are frequently used in structural applications such as building frames and bridges.
- Anchor bolts are specifically designed to anchor structures to concrete, masonry, or other materials and are commonly used in foundation work to secure steel columns to concrete.
- Carriage bolts, with a rounded head and square shoulder, are typically utilized in wood-to-wood and metal-to-wood connections.
- Lag bolts, on the other hand, have a threaded shaft and a hex head and are used to attach heavy objects to wood, such as deck attachments to a house.
- Eye bolts are engineered with a looped end that allows for the attachment of cables, ropes, and chains and are typically utilized in rigging and lifting applications.
- U-bolts are characterized by their U-shape and are used extensively in securing pipes, tubes, and cables to structures.
- Flange bolts have a wide, flat head that evenly distributes the load over a larger area, making them ideal for use in automotive and industrial applications.
AGICO has been supplying construction bolts for various projects: railway tunnel segment bolts, holding-down anchor bolts for building foundations and bridge-bearing bolt. Construction project must choose bolts designed for specific applications and follow appropriate installation procedures, quality control and installation procedure must be put in place to ensure the fastening reliability and safety.
