Also known as grub screws, they are characterized by a headless design. Set screws still have a threaded body like standard bolts. Rather than a traditional flared head, however, they feature an internal drive mechanism on one end. Here are five things to consider when choosing a set screw.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#1) Material<\/h2>\n\n\n\n<p>Not all set screws are made of the same material. Some of them are made of hardened alloy steel. These heavy-duty set screws are commonly used in structural and mechanical assemblies. There are also set screws made of heat-treated alloy steel. They can often withstand up to 170,000 pounds per square inch (PSI) of pressure. For wet or humid environments, you may want to choose a stainless steel set screw. Stainless steel screws aren&#8217;t as strong as their hardened and heat-treated counterparts, but they offer a superior level of protection against corrosion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#2) Point Type<\/h2>\n\n\n\n<p>Set screws are available in different types of points. Some of them have a flat point. Other set screws have a cup point or a cone point. Each point type has its own advantages. Flat-point set screws are better suited for hard surfaces. Cup-point set screws feature sharp edges that dig into surfaces. Cone-point set screws offer the strongest and most secure hold.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#3) Drive Type<\/h2>\n\n\n\n<p>You should consider the drive type when choosing a set screw. As previously mentioned, they have an internal drive type. Common drive types for set screws include hex and square. Hex-style set screws have a six-sided recess on one end, whereas square-style set screws have a four-sided recess on one end.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#4) Thread Pitch<\/h2>\n\n\n\n<p>The thread pitch represents the distance between a set screw&#8217;s individual threads. With SAE measurements, it&#8217;s typically measured in threads per inch. A set screw with a thread pitch of 32, for instance, has 32 threads per inch. With metric measurements, thread pitch is measured in millimeters. The higher the thread pitch, the farther apart the screw&#8217;s threads will be.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#5) Surface Treatment<\/h2>\n\n\n\n<p>What type of surface treatment does the set screw have? For additional protection against chemicals and environmental contaminants, many set screws are coated in a protective layer or finish. Cadmium is commonly used as a surface treatment for set screws. It holds up well in even the toughest environments. Zinc is another popular choice for set screws. It offers good corrosion resistance at a lower cost than many other surface treatment options.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Set screws are commonly used to secure pulleys and gears to shafts.
