Types of Industrial Fasteners and Their Applications
Industrial fasteners create removable or permanent joints in machinery, structures, equipment and OEM assemblies. Selection should be based on load, joint design, environment, material compatibility, thread standard and installation method.
Common Industrial Fastener Types
Bolts
Hex bolts, socket bolts, carriage bolts and anchor bolts are used with nuts or threaded holes for structural and mechanical joints.
Screws
Machine screws, self-tapping screws and socket screws serve equipment, sheet metal, electrical and precision assembly applications.
Nuts
Hex nuts, flange nuts, lock nuts and cap nuts provide different locking, load distribution and appearance functions.
Washers
Flat, spring and specialized washers distribute load, protect surfaces or support locking requirements.
Threaded Rods and Studs
These components support adjustable connections, equipment mounting and long clamping lengths.
Rigging Hardware
Eye nuts, turnbuckles, wire rope clips and related fittings are selected according to the specific connection and service requirements.
Materials and Finishes
Options may include stainless steel, carbon steel, alloy steel, brass or another specified material. Zinc plating, galvanizing, black oxide and passivation have different limitations, so finish selection must reflect the service environment.
Selection Checklist
- Applicable thread and dimensional standard
- Required strength or property class
- Corrosion and temperature exposure
- Joint material and installation access
- Inspection, traceability and packaging requirements
Applications
Industrial fasteners are used in machinery, construction systems, solar mounting, automotive assemblies, marine hardware, enclosures and production equipment.
