What are Precision Screws?

Precision fasteners are made to tight tolerances and are of higher quality than standard fasteners. As we said precision screws are normally micro screws designed for a variety of purposes, though most are primarily intended to fasten two surfaces together. In fact, it has many kinds of threads, not only one.

Types of Precision Screws

Machine Screws: Precision screws generally have two types of thread, one is machine thread and the order is self-tapping, the difference between these two products is the type of thread and the angle of the thread, for precision screws of machine thread, the screws are often driven into tapped holes, or are used alongside Nuts to fasten components together. The thread pattern of the machine screws is usually relatively fine, and it is relatively simple to use. When assembling the product, just twist the screw into the component and tighten it, which plays a fixed role.

Self tapping Screws: The other is self tapping precision screws, most of which are used on non-metallic products, contrary to machine screws, self-tapping screws are screws that have the ability to tap threads into the material. and most of them are used in plastic materials, their thread shape is closely related to the material hardness and bearing capacity of the plastic materials, for different materials, the types of self-tapping thread involved are also different, and the self-tapping screw has a better anti-falling effect.

Precision shoulder screws: also known as shoulder bolts are fasteners with an unthreaded cylindrical section, or shoulder, between threads and the screw head. The shoulder is larger in diameter than the threaded section and provides an axis around which close-fitting moving parts operate. Made to tight dimensional tolerances and offered in inch and metric sizes. Low-profile and thread-locking options are available by request

Precision Dowel Pins: Precision Dowel Pins are a type of fastener that can be used to hold material together or hold an item in place. Pins are often used in places the use of a threaded fastener is not possible or desirable. precision ground with consistent diameters and chamfered ends. Use as a fastener or locating device in motorized applications. An inch or metric size.

Grub Screws: Grub Screws are also called set screws. The grub screw is generally used to secure an item against another item and does not feature a head, which allows them to be fully driven into a pilot hole without nuts, This is important, because the ability to secure without a nut makes the grub screw very versatile, and means that a grub screw can be used in applications that require a very small and unobtrusive fixing

Left Hand Threaded Screws: a screw thread whose helix moves upward when the screw is inserted vertically from above in a fixed mating thread and turned clockwise. and are used more commonly in automotive repair and as a safety feature in the storage of flammable gas. Our Left-Hand Threaded Screws are designed for use alongside our range of Left-Hand Threaded Nuts.
