Types of Connection Fasteners: A Complete Guide

Connection Fasteners are the backbone of countless construction, manufacturing, and repair projects. These essential hardware components join materials together, creating secure and durable bonds that withstand stress, vibration, and environmental factors. Whether you’re building a skyscraper or assembling furniture, understanding the different types of connection fasteners helps you choose the right solution for your specific application.

This guide explores the most common types of connection fasteners, their strengths, uses, and applications to help you make informed decisions for your next project.

Bolts: Heavy-Duty Connection Solutions

Bolts represent one of the strongest and most reliable types of connection fasteners available. These threaded fasteners work in conjunction with nuts and washers to create removable joints that can handle significant loads.

Key Strengths:

• Exceptional tensile and shear strength
• Easy to install and remove
• Suitable for thick materials
• Provides consistent clamping force

Common Uses:

• Structural steel connections
• Heavy machinery assembly
• Automotive applications
• Bridge construction

Popular Types:

• Hex bolts: Feature hexagonal heads for wrench application
• Carriage bolts: Round heads with square necks prevent rotation
• Eye bolts: Include loops for lifting and rigging applications
• U-bolts: Curved shape ideal for pipe and conduit mounting

Connection fasteners sizes for bolts typically range from 1/4 inch to 4 inches in diameter, with lengths varying based on application requirements.

Screws: Versatile Threading Champions

Screws offer incredible versatility among connection fasteners, creating their own threads as they’re driven into materials. This self-tapping capability makes them ideal for applications where access to both sides of the joint isn’t possible.

Key Strengths:

• Self-threading capability
• Wide variety of head styles
• Excellent holding power
• Cost-effective solution

Common Uses:

• Wood construction and carpentry
• Sheet metal fabrication
• Electronic device assembly
• General maintenance and repair

Popular Types:

• Wood screws: Coarse threads designed for lumber applications
• Machine screws: Fine threads for metal-to-metal connections
• Self-drilling screws: Combine drilling and fastening in one operation
• Drywall screws: Specialized for gypsum board installation

Many connection fasteners manufacturers in India produce screws in standard sizes ranging from #2 to #14 gauge, with metric options also widely available.

Rivets: Permanent Connection Specialists

Rivets create permanent joints by deforming during installation, making them ideal for applications requiring tamper-resistant connections. These connection fasteners excel in high-vibration environments where threaded fasteners might loosen over time.

Key Strengths:

• Permanent, tamper-resistant connection
• Excellent vibration resistance
• Smooth, finished appearance
• No risk of loosening

Common Uses:

• Aircraft and aerospace assembly
• Bridge and structural connections
• Automotive body panels
• Sign and billboard construction

Popular Types:

• Solid rivets: Traditional rivets requiring access to both sides
• Blind rivets: Can be installed from one side only
• Drive rivets: Simple installation with hammer or pneumatic tool
• Structural rivets: Heavy-duty options for load-bearing applications

Other Types of Fasteners

Beyond the primary categories, several specialized connection fasteners serve unique applications:

Anchors and Inserts:

• Concrete anchors for masonry applications
• Threaded inserts for soft materials
• Toggle bolts for hollow wall mounting

Specialty Fasteners:

• Clips and clamps for temporary connections
• Pins and dowels for alignment applications
• Washers and spacers for load distribution

Quick-Release Options:

• Thumb screws for tool-free adjustment
• Quarter-turn fasteners for access panels
• Camloc fasteners for removable covers
