Choosing the right bolt requires comprehensive consideration of its type, performance grade, and applicable application scenario; all three are indispensable. Incorrect matching can lead to connection failure, safety hazards, or wasted costs. The following is a systematic selection guide to help you make accurate decisions.
Selecting by Bolt Type: Structure Determines Application
Hex Head Bolts
Features: Hexagonal head for easy tightening with wrenches or sockets; high load-bearing capacity.
Applicable Scenarios: High-strength connections in mechanical equipment, building steel structures, automotive chassis, etc.
Counterhead Bolts
Features: Tapered head that can be embedded in the workpiece, resulting in a smooth surface after connection.
Applicable Scenarios: Instrument panels, furniture trim, etc., where appearance is important.
Socket Head Bolts
Features: Head with an internal hexagonal hole, saving space and providing good anti-loosening properties.
Applicable Scenarios: Space-constrained locations in precision machinery, molds, and automated equipment.
T-slot bolts
Features: The T-shaped head allows for sliding positioning within the profile slot.
Applications: CNC machine tools, aluminum profile frames, industrial workbenches.
Anchor bolts
Features: Used to fix equipment to concrete foundations; one end often has a hook or anchor plate.
Applications: Tower cranes, bridge supports, large motor bases.
U-bolts
Features: The U-shaped structure clamps tubular objects.
Applications: Water pipes, cable trays, automotive leaf spring fixing.
