While they all have external threading, some of them are designed differently than others. Fortunately, you can often refer to abbreviations to identify screw types.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FH<\/h2>\n\n\n\n<p>Screws with the FH abbreviation are flat-head screws. Also known as countersunk screws, they feature a flat head that&#8217;s tapered on the side. Flat-head screws will rest flush with the surface of the material in which they are installed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">BH<\/h2>\n\n\n\n<p>You may come across screws with the BH abbreviation. The BH abbreviation indicates button head. Button-head screws have a dome-shaped head, which allows them to protrude out of the material in which they are installed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">MS<\/h2>\n\n\n\n<p>One of the most common screw abbreviations is MS. MS screws are machine screws. Machine screws are short, heavy-duty screws that feature uniform threading. As their name suggests, they are used in machine-related fastening applications. If you need to hold two or more machinery parts together, you should consider using a machine screw.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PH<\/h2>\n\n\n\n<p>Screws with the PH abbreviation feature a Phillips head drive recess. The top of the head, for instance, has a cross-shaped cutout. To install a Phillips head screw, you&#8217;ll need to place a bit of the same type in this recess, after which you can turn the bit clockwise. Screws with the PH abbreviation are characterized by a Phillips head drive recess such as this.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FT<\/h2>\n\n\n\n<p>Some screws have the FT abbreviation. The FT abbreviation indicates a fully threaded shank. All screws have a shank. The shank is the main part of a screw. Screws have a head, followed by a shank. If you come across a screw with the FT abbreviation, it&#8217;s safe to assume the shank is fully threaded. Threading will completely cover the screw&#8217;s shank &#8212; all the way from the head to the tip.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">SH<\/h2>\n\n\n\n<p>While not as common as a Phillips head, some screws have a socket head. Socket head screws typically have the SH abbreviation. They still have a drive recess. Socket head screws, however, don&#8217;t have the same cross-shaped drive recess as their Phillips head counterparts. Rather, they have a hexagonal recess. You can install them using a hex key or socket bit.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">STS<\/h2>\n\n\n\n<p>The STS abbreviation indicates that screw is self-tapping. They feature a tip that&#8217;s similar to the tip of a drill bit. With this tip, self-tapping screws are able to tap their own.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">SS<\/h2>\n\n\n\n<p>The SS abbreviation may have different meanings. In some cases, it&#8217;s used to describe screws made of stainless steel. In other cases, the SS abbreviation is used to describe set screws.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Not all screws are the same.
