When deciding which fasteners would be best to use for a project, there are several ways to decode their grade. All fasteners come with specific markings to help determine material, make, and grade. Some small size fasteners will not be graded with a specified strength, but larger size fasteners and specialized fasteners are meant to meet specific strength requirements. When replacing a graded fastener, use a replacement the same grade or higher. Recognizing Bolts By
A fastener drive is a set of shaped cavities and protrusions on the fastener head that allow for the use of a mating tool, such as a screwdriver, to apply torque. Understanding a drive’s purpose and the differences between drives will help you decide which style you should choose for your specific project. Slot This drive has a single horizontal indentation in the fastener head and is driven by a “common blade” or flat-bladed screwdriver.
Fasteners need to perform reliably in all applications. It’s important to be aware of the factors that can affect that performance, particularly in high heat situations. Utilizing the wrong fasteners under high heat can cause weakening, disintegration or even vaporization. Bolts can be made of a variety of materials, including carbon steel, alloy steel and stainless steel, but high-temperature applications call for iron, nickel and chromium-based alloys. This awareness of fastener selection for high-heat applications
When it comes to fasteners, threads are key. Threads determine how well fastener components (like nuts, bolts and screws) hold materials and machines together, and maintain their integrity over time. The two main types of threads are coarse and fine, and while both types have their advantages and appropriate uses, coarse threads typically win in our book. Read on to learn the basics of these two types of threads and when you might consider
Quality is key for any product selection. When it comes to fasteners, quality is defined by durability and resilience. Clients want fasteners that will last! Fasteners can have a variety of coatings, and the application (where and how the fastener will be used) usually dictates which coating makes sense. Read on to learn about the most popular coatings and their best-use scenarios. Why is it important to select the right coating? Because fasteners connect or
