Stainless steel screw, also known as sems screw, refers to a three combination fastener composed of a cap and a flat washer with a thread. The threads of the screw may be turned by hand or may be threaded through a machine tool. Generally call it a semi-round screw. The screws in this kind of screw are commonly called flat-head screws, cup-head screws and hex-headed screws.
This kind of fastener is usually used to attach timber flooring to concrete slabs or floor joists. It is also used for attachment to light fittings and pipes. A variety of threaded fasteners are available, however it is the same screw that has received much attention because it is stronger, safer and more economical than most of them. The following explanation will give you an idea about the working of the set screw and how it is used:
In order to attach the timber flooring to the concrete slab, you need to make a right round shape recess in the surface of the floor. You then use one of the two-pronged screws to fasten the steel washers into these washers. The other side of the fastener has holes in it, which are used to thread the other part of the flexible steel strip through.
The locking mechanism of the set screw is similar to that of other fasteners like tap nuts and wing nuts. However, the threads of this fastener are closer together than tap nuts and wing nuts. The threads of this fastener are also tapered. The flat plate on which the screw of the SEMS is mounted has an external thread on one side that threads through a hole on the other side. You need to drill this hole before tightening the locking nut that is also known as a crimping tool.
The external threads of the SEMS screws are tapered, which ensures that the fastener is very safe to handle. It has small flat cutting teeth that are designed to pierce through the toughest materials. The interior teeth of this fastener are tapered, which helps the fastener slip easily into tight places. This feature makes the semi-automated slot machine system possible to use the SEMS screws for any application.
These screws have been in use for decades and they continue to gain popularity because of their excellent performance and great safety features. They can work in high temperatures and are very effective in drilling holes into soft metals. Another benefit of using SEMS fasteners is that they do not need lubrication, which means that you do not have to clean the lubricant from these washers after you are finished using them. The other benefits include: they require low maintenance cost and they are available in different sizes.
