Types of Fasteners: Bolts, Nuts, Screws, Washers and More

Fasteners are essential components that hold objects together securely. From skyscrapers and bridges to your desk chair and kitchen cabinets, fasteners make everything function. Whether you’re a mechanical engineer, DIYer, or industrial contractor, knowing the types of fasteners is key to achieving reliable builds.
Why Quality Fasteners Matter
Using the right type and quality of fastener can make or break your project. Poor-quality fasteners can cause structural failure, loosen under stress, or corrode over time. That’s why professionals rely on trusted brands like Flexpipe’s Fasteners, which are known for high tensile strength, precision threading, and anti-corrosion coatings.

Mechanical Fasteners
-
Bolts
Bolts are threaded fasteners designed to be paired with nuts. Common types include hex bolts, carriage bolts, and flange bolts.
-
Nuts
Nuts secure bolts in place. Types include hex nuts, lock nuts, wing nuts, and cap nuts.
-
Screws
Screws have helical threads and don’t always require a nut. From wood screws to sheet metal screws, they provide secure fastening in various materials.
-
Washers
Placed between the head of a fastener and the material surface, washers prevent loosening and distribute the load.
-
Rivets
Rivets are permanent fasteners used in applications where welding isn’t feasible. Flexpipe’s pop rivets and solid rivets are highly rated for industrial use.
Threaded Fastener
-
Machine Screws
Machine screws fasten components by either threading into an existing tapped hole or by securing with a nut. They’re ideal for precision work and electronics.
-
Self-Tapping Screws
These create their own threads in metal or plastic. Perfect for reducing installation time.
-
Set Screws
Used to secure an object within another, such as fixing a pulley to a shaft.
Permanent Fastener Types
-
Snap Rings
Snap rings hold components onto shafts or inside housings, ideal for machinery.
-
Welding Fasteners
Used for spot-welded joins in the automotive or aerospace sectors.
-
Rivet Nuts
Rivet nuts combine the function of rivets and nuts, excellent for hollow sections or thin panels.
Temporary Fastener
-
Clips and Clamps
Perfect for applications that require disassembly, like automotive panels.
-
Cotter Pins
Used with bolts and nuts to secure machinery parts temporarily.
-
Cable Ties
Common in electrical work, they bundle wires and are easy to remove and replace.
Specialty Fasteners
-
Anchors
Used to secure objects to concrete or masonry. Includes sleeve anchors, wedge anchors, and drop-in anchors.
Flexpipe offers a wide range of anchors with high load-bearing capacity and weather resistance.
How to Choose the Right Fastener
Here’s what to consider:
| Factor | Why It Matters |
|---|---|
| Material | Steel, brass, or aluminum, depending on the environment |
| Thread Type | Coarse for grip, fine for precision |
| Head Type | Flat, hex, pan, and truss for function & aesthetics |
| Coating | Zinc-plated, black oxide, or galvanized for corrosion resistance |
| Size & Length | Always based on application and stress distribution |
