When looking at fasteners, you have to decide whether you want imperial fasteners or metric fasteners. When designing new products metric dimensioning should be considered as a low-cost solution to fastener assembling.
There are two types of metal fasteners
Those that create a permanent bond and those that need either a releasable or sliding bond. Examples in the first group include screws, nuts and bolts, rivets, retaining rings and clamps. Non-permanent fasteners involve quick-release couplers and clamps designed to be removed at a specified time and pins enabling the relative movement of the fastener sections.
To bear significant loads, metal fasteners must be solid. In certain situations, powder metallurgy or casting methods may be used to produce them. Iron is a part of many types of metal fasteners, while titanium is increasingly being used in applications where strength and lightweight must be matched. Metal fasteners can be replaced by some form of welding or welding in most applications in which permanent bonding is necessary.
What are Metric fasteners?
They function with a near-universal unit of measurement when dealing with metric fasteners, although there are a few notable exceptions to this law. Look at the metric system with a certain amount of ambivalence. The metric system has been the de facto measurement standard in the world, even with these notable exceptions, so let's see why decimalization with the imperial system stands toe-to-toe.
Benefits of Metric Fasteners
It is a simple form of measurement with a base of whole numbers. This can help reduce the number of fasteners in a bill of materials.
Metric thread falls between an inch course and fine thread. This allows the designer to take advantage of both thread types. It’s a better choice for vibration resistance as well as providing a larger stress area in the cross-section of the screw. A commercial finish can be applied without gaging issues.
