Fasteners gets a vital place in the hardware family. When used with counterparts like ‘nuts’ fasteners help fix things. Do you think there's nothing unknown about it? In this article, we are going to discuss some unknown interesting facts about Stainless Steel Screw fasteners that will pick your interest for sure.

First things first! Let’s get into the basics –

Fasteners are mechanical tools that are used to join more than one metallic and not metallic object temporarily. Generally, fasteners are made of either metal like alloy steel, carbon steel, stainless steel, or plastic. Commonly stainless steel fasteners are used mostly because of their low price, longevity, and availability.

Application of Fasteners

From our houses to big industries, fasteners are used in many components, starting from a small wrist-watch to big machines. Here are some areas where fasteners are commonly used:

  • Home appliances
  • Furniture
  • Construction of buildings
  • Aerospace
  • Marine
  • Automobile

5 Interesting Facts about Fasteners


Do you know that Socket Head Cap Screw (SHCS), which are used in joining sockets made of black oxide alloy steel, are usually not "grade 8" fasteners?

Grade 8 fasteners are known for their strength and availability. It should have some specific characteristics to be a grade 8 fastener according to the market standards. But SHCS possess far better quality than grade 8 fasteners like tensile tension, labeling upon the handle, and stiffness. Thus SHCS is next to the Grade 9 fastener and better than Grade 8 fasteners.


Do you know how many threads or fasteners are used to join the plate in a tapped area?

It mostly depends on the length, but not more than six. When load is added, nuts and bolts may extend in length. Hence, the load differs on each thread. When a tensile weight is assigned on one clutched string, the first string near the joint receives most of the weight, and then the load begins to decrease. It continues reducing till the sixth thread, after where no more distribution of weight occurs.


Do you know the fasteners used in textile made of harsh or fine fabric also have drawbacks?

We can use all fasteners as either fine fabric or course. Fine threaded fasteners have more stress areas than harsh threaded ones of the same dimension. So you are recommended to use a fine threaded bolt for better tensile durability if the dimensions are fixed. Fine threads are also used to stick a thin wall, and when joining a small area as fine threads are efficient and can be used with accuracy. Loosely bound threads are used for temporary joining. Coarse threads are used in the materials, which may be exposed to nature directly as they have more longevity.


Isn't it interesting that stainless steel screw fasteners have ranks like 1A, 1B, 2A, 2B, 3A, 3B?

The letters and the numbers are assigned to denote the rating of the quality of the fasteners. 1A and 1B fasteners are of the lowest grades. They're not so durable, and that's the main reason to use them as a temporary fix. 2A and 2B fasteners are commonly used as affordable and not so bad in terms of durability. 3A and 3B are costly and better than others. They are usually used for the crucial joints.


Do you know that bolts should be tightened when fatigue weight is applied?

A bolt may undergo zero load shift if the tensile force is larger than the joint or attachment's comprehensive intensity. It's proved that a firmly attached bolt can adapt faster to the fatigue load than a loosely fastened one, as in such cases the bolt does not go through a load of fatigue but the continuous stress that is exerted by the clamping of the joint. This is because tightened bolts provide quick load adaptability than loosely fastened joints. Keep in mind that you should apply the torque on the bolt rather than the nuts.

Now that you have found out all the facts about the fasteners and tested your knowledge, you can always use it when an opportunity comes.
