Types of Screws
Machine screws
ASME standards specify a variety of “Machine Screws” in diameters ranging up to 0.75 in (19.05 mm). These fasteners are often used with nuts but also often driven into tapped holes (without nuts). They might be considered a screw or a bolt based on the Machinery’s Handbook distinction. In practice, they tend to be mostly available in smaller sizes and the smaller sizes are referred to as screws or less ambiguously as machine screws, although some kinds of machine screw can be referred to as stove bolts.

A fastener with a built in washer is called a SEM or SEMS, short for pre-asSEMbled. It could be fitted on either a tapered or non-tapered shank. Sems screws can have one or more flat or lock washer under the head already assembled.
A self-tapping screw is a screw that can tap its own hole as it is driven into the material. A self-tapping machine screw is similar to a machine screw except the lower part of the shank is designed to cut threads as the screw is driven into an untapped hole. The advantage of this screw type over a self-drilling screw is that, if the screw is reinstalled, new threads are not cut as the screw is driven.
Captive screws are snapped into position just using thumb pressure. Invaluable for equipment panels where mounting hardware is subject to loss, these captive screws and retainers assure easy and secure assembly.

What are countersunk screws used for - Yuhuang Electronic Technology

What are countersunk screws used for - Yuhuang Electronic Technology A screw is a type of fastener, sometimes similar to a bolt, typically made of metal, and characterized by a helical ridge, known as a male thread or just thread. Countersunk Screws A common use is to allow the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material. Countersunk heads are often used in soft and hard woodworking applications. Countersinking is especially necessary when working with hardwoods. Countersunk screws are a type of fastening that sits flush with the surface of the material it occupies. These screws typically are used so that you can cover them easily with either a screw cap or piece of wood. Other applications include the need for a fastening not to protrude so other objects can rest upon it stably, or to fasten it further to another object. The typical angle of a countersunk screw head is 82 degrees, but this varies dep

What are deck screws from Yuhuang Electronic Technology Co., Ltd. Deck screws : Similar to drywall screw except that it has improved corrosion resistance and is generally supplied in a larger gauge. Most deck screws have a type-17 (auger type) thread cutting tip for installation into decking materials. They have bugle heads that allows the screw to depress the wood surface without breaking it. Bugle head :  Similar to countersunk, but there is a smooth progression from the shank to the angle of the head, similar to the bell of a bugle. Drive style of screws Modern screws employ a wide variety of drive designs, each requiring a different kind of tool to drive in or extract them. The most common screw drives are the slotted and Phillips in the US; hex, Robertson, and Torx are also common in some applications, and Pozidriv has almost completely replaced Phillips in Europe. Some types of drive are intended for automatic assembly in mass-production of such items as automobiles. More exotic

What are Chicago screws? From Yuhuang Electronic Technology

What are Chicago screws? From Yuhuang Electronic Technology Chicago screws, which are also known as a barrel nut, barrel bolt, sex bolt, post and screw or connector bolt. Chicago screws is a type of fastener (nut) which has a barrel-shaped flange and protruding boss that is internally threaded. The boss sits within the components being fastened, the flange provides the bearing surface. The sex bolt and accompanying machine screw sit flush on either side of the surfaces being fastened. It is normally chosen because of its low profile compared to other nuts. The sex bolt often has a built-in feature, such as a slot, to aid in tightening the fastener. Some sex bolts, more commonly known as ‘architectural bolts’, have knurled barrels to allow one-sided assembly. ‘Binding posts’ are similar to architectural bolts in that they are designed to be assembled from one side, but they have teeth on the flanged surface to keep them fixed. A sex bolt is a mating fastener combining a fastener (nut)
