Types of Fasteners

Threaded fasteners
Threaded fasteners are designed with threads (either external or internal) that allow them to be screwed into a material or used in conjunction with a nut. They create strong, secure connections, ideal for high-stress applications.

Bolts: These are externally threaded fasteners that typically require a nut for tightening. Bolts are commonly used in construction and machinery due to their ability to hold heavy loads.

Screws: Screws have external threads and can be driven directly into materials, usually pre-tapped holes. They come in various head and drive types, such as Phillips and Slotted, making them versatile for different applications.

Nuts: Nuts are internally threaded components used to secure bolts or threaded rods. They are essential for through-hole applications and can include specialized types like lock nuts to prevent loosening.

Non-threaded fasteners
Non-threaded fasteners do not have threads and are typically used for applications where permanent or semi-permanent joints are required. These fasteners are often used in environments where high shear strength is needed.

Rivets and washers: Rivets are inserted into pre-drilled holes and deformed to hold materials together securely, while washers are used to distribute load and prevent damage to the material.

Pins: Pins, such as cotter pins or dowel pins, are used to align or secure components. They can be temporary or semi-permanent, depending on the application.

Benefits of Using Fasteners

Strength and durability

The right fastener ensures your structure holds together over time, even with frequent use or exposure to the elements.

Ease of repair and adjustment

Modular fasteners mean you can swap out parts or change layouts with minimal effort, saving you time and money.

Versatility

Modern fasteners work with many materials, making them perfect for mixed projects involving wood, metal, or plastic.

Safety

High-quality fasteners reduce the risk of failures, which is crucial in both home and industrial settings.

Aesthetics

Neatly installed fasteners improve the overall look of a project, giving it a professional finish.

The Many Uses of Fasteners

Construction

They are used in building construction to hold together various components such as framing, roofing, and drywall. Screws, nails, and bolts are commonly used to attach wood and metal components, and adhesive is used to seal and attach various materials.

Manufacturing

Several products, such as automobiles, appliances, and electronic devices, rely on them. It is common to use screws, bolts and snaps to hold components together and make them easy to disassemble and repair.

Furniture manufacturing

Furniture parts, such as chairs, tables, and cabinets, are held together with these screws. Screws, nails, and dowels are commonly used to attach legs, supports, and other components.

Maintenance and repair

They are used to repair or maintain various objects and machines, such as cars, appliances, and equipment. Screws, bolts, and nuts are commonly used to hold parts in place and make them easy to disassemble for repair.

Medical equipment

Medical equipment such as surgical instruments, prosthetic devices, and diagnostic equipment is held together by a variety of fasteners. Screws, bolts, and snaps are commonly used to attach components and make them easy to disassemble for repair.

FAQ

Q: Why is it called fasteners?

A: Since the late 18th century, the term has been used specifically to refer to mechanical devices that serve the purpose of joining or affixing objects together. The term “fasteners” encompasses a wide range of items, including screws, bolts, nuts, washers, as well as bushings, pins, and threaded inserts.

Q: What applications are fasteners used for?

A: Permanent fasteners are single-use, intended to join two materials and — as the name suggests — can't be removed once installed. Permanent fasteners are used widely throughout many industries, including automotive and consumer electronics. Examples of common permanent fasteners include rivets, nails or welds.

Q: What is a class 3 fastener?

A: Class 3 threads are tight tolerance threads that have no allowance and have very tight tolerances. Class 3 threads are often specified for tight tolerance fastener applications in critical use situations where safety and strength are a primary concern, such as the aerospace industry.

Q: What is a 12 point fastener?

A: 12-point bolts are also known as 12-point flange bolts. They have a flange diameter and head thickness that are equivalent to a socket head cap screw.Mar

Q: What are fasteners used for in construction?

A: Fasteners are the backbone of any construction project, holding materials together and providing strength and stability. From screws to nails, bolts, and anchors, each fastener type has unique applications. Choosing the right fastener for your project ensures durability, safety, and success.

Q: What are grade 5 fasteners?

A: Grade 5 fasteners are made from medium carbon steel and are heat treated to increase their strength. They are stronger than grade 2 fasteners, but not as strong as grade 8 fasteners. Grade 5 fasteners are commonly used in automotive and construction applications where a higher level of strength is required.
