FASTENER
Fasteners, essential mechanical components, are used to join or secure two or more objects together. From construction sites to electronic devices, fasteners play a crucial role in various industries.
Common Materials
- Stainless Steel: Known for its corrosion resistance and durability, stainless steel fastener are widely used in industries like oil and gas, chemical processing, food processing, and construction.
- Nickel Alloys: Offering exceptional heat resistance and corrosion resistance, nickel alloys are ideal for demanding applications such as chemical processing, aerospace, marine, and power generation.
- Copper Alloys: Copper and its alloys are valued for their excellent thermal and electrical conductivity, corrosion resistance, and malleability. They find applications in plumbing, HVAC systems, electrical wiring, and heat exchangers.
- Aluminum Alloys: Lightweight and corrosion-resistant, aluminum alloys are used in applications where weight is a concern, such as automotive, aerospace, and construction.
- Titanium Alloys: With a high strength-to-weight ratio and excellent corrosion resistance, titanium alloys are suitable for aerospace, medical implants, chemical processing, and marine applications.
Manufacturing Process
- Cold Forging: This process increases the strength and durability of fasteners by aligning the grain structure of the metal.
- Hot Forging: Involves heating the metal until it becomes malleable and shaping it into the desired form.
- Machining: Machining processes are used to produce various types of fasteners, such as screws and bolts.
- Thread Forming: Thread forming fasteners create threads within a pre-drilled hole rather than cutting them.
- Cold Forming of Nuts: Cold forming involves shaping metal blanks into nuts at room temperature or slightly above.
- Heat and Surface Treatment: Heat treatment processes like hardening and tempering improve the mechanical properties of fasteners.
Key Features
- Thread Type: Fasteners can have various thread types, such as machine threads, self-tapping threads, and wood threads.
- Head Types: Different head types include hexagonal, Phillips, slotted, and socket heads.
- Coatings: Coatings like zinc plating, galvanization, or organic coatings enhance corrosion resistance and appearance.
- Strength Class: Fasteners are classified based on their strength, with grades like ASTM A193 for bolts and ASTM F593 for stainless steel bolts.
