Common Fastening Systems for Driving Steel
Several fastening systems are employed specifically for driving steel components, depending on the application, type of steel, and structural requirements. These systems are designed to provide strong, durable, and often removable connections, ensuring the integrity of steel structures or assemblies.
Mechanical fastening is the most common method for driving steel parts together. This includes:
- Bolting: Using bolts and nuts to join steel parts. Bolted connections allow for easy disassembly and are widely used in structural steel frameworks, bridges, and machinery.
- Riveting: Once a dominant method, riveting involves deforming the end of a metal pin to hold steel parts together. Though less common today, it remains in use for certain repair works and aircraft manufacturing.
- Welding: Although technically a joining process rather than a fastening system, welding fuses steel parts together and is often considered when discussing steel assembly.
For fastening smaller steel components or attaching steel to other materials, specialized systems include:
- Self-drilling and self-tapping screws: These fasteners are designed to drill their own hole in steel and tap threads simultaneously, speeding up assembly.
- Nail guns with hardened steel nails: Used primarily in light steel framing, these systems use nails designed to penetrate steel with minimal deformation.
Types of Fasteners Used in Steel Driving
Different fasteners are selected based on the steel thickness, environmental conditions, and load requirements:
- High-strength bolts: Often used in structural steel applications, these bolts conform to standards like ASTM A325 or A490, offering high tensile strength.
- Concrete anchors: When steel is driven into concrete or masonry, specialized anchors such as wedge anchors or sleeve anchors are employed.
- Blind rivets: Useful in situations where access is only available from one side, blind rivets are used to fasten thin steel sheets or panels.
- Threaded inserts: Installed in steel components to provide a durable threaded hole for assembly with bolts or screws.
