Screws & bolts

What are Fasteners and Fixings?
Fasteners and fixings are hardware devices used to join or secure two or more objects together. They come in various shapes, sizes, and materials, and are designed to withstand different levels of tension and pressure. Some common types of fasteners and fixings include screws, bolts, nuts, washers, and threaded rods. In the construction and manufacturing industries, they play a crucial role, holding everything from small gadgets to large structures together.

Types of Fasteners and Fixings

Screws
Screws are one of the most commonly used fasteners. They have a threaded shaft and a head that can be turned with a screwdriver or drill. Screws are available in different sizes and materials, such as wood, metal, and plastic, making them versatile for various applications.

Bolts
Bolts are similar to screws, but they have a larger diameter and are typically used with a nut to secure two objects together. They are commonly used in construction and automotive industries, and are available in different lengths and materials.

Nuts
Nuts are used in conjunction with bolts to secure objects together. They come in various shapes and sizes, including hex, square, and wing nuts. Nuts are typically made of metal and can be tightened with a spanner.

Washers
Washers are thin, flat discs with a hole in the centre. They are placed between the head of a screw or bolt and the surface it is being fastened to. While not fasteners themselves, washers help distribute the pressure and prevent damage to the surface being fastened.

Threaded Rods
Threaded rods, also known as studs, are long, straight rods with threads on both ends. They are commonly used in construction and plumbing projects to join two objects together. Threaded rods are available in various lengths and materials, such as steel, stainless steel, and brass.

Uses of Fasteners and Fixings
Fasteners and fixings have a wide range of uses in construction, manufacturing, and DIY projects. They are essential for holding together structures, furniture, and machinery. Some common applications include:

• Building and construction: Fasteners and fixings are used to secure beams, frames, and other structural elements in buildings.
• Furniture assembly: Screws, bolts, and nuts are commonly used to assemble pieces of furniture.
• Automotive industry: Fasteners and fixings are used to hold together various components in vehicles.
• Plumbing: Threaded rods and nuts are used to secure pipes and fittings in plumbing systems.

Selecting the Right Fastener or Fixing

Material Compatibility
The material of your fastener should be compatible with the materials you are joining. For instance, stainless steel fasteners are ideal for outdoor applications due to their corrosion resistance.

Size and Length
The size and length of your fastener are critical. Too long, and it may protrude unnecessarily; too short, and it won’t hold the materials effectively.

Load Requirements
Consider the load your fastener will need to support. Heavier loads require stronger fasteners, like high-tensile bolts.

Environmental Conditions
Environmental factors such as moisture, temperature changes, and chemical exposure can affect the performance of fasteners. Choose materials and coatings that can withstand these conditions.
