Benefits Of Vibration Resistant Fasteners

By George Schmidt


Joining of parts in engineering is has many approaches such as gluing, welding, riveting or use of nuts and bolts. All these are referred to us fasteners. The widely use type of fastener in engineering is the bolts and nuts. They provided a way to disassemble the parts without having to destroy the fastener and the part. In most machines, vibrations have been a major cause in their damages. Thus a solution to dampening or making vibration proof fasteners came up. Below are some reasons for vibration resistant fasteners.

They enable fine engineering where machines and equipment made have the right precision and accuracy required. This is because they have been made with enough care to be able to reduce any external forces like tension thus are able to withstand vibrations much better. They are also designed to be able to measurable and thus can be measured in several ways thus can be applied in the making of precision equipment.

They also avoid losing of nuts and bolts since they do not get lost after getting loose. The non-shock proof fasteners are easily lost and their level of safety is questionable after a certain time. They usually are therefore secured and much more preferred in machines or equipment that calls for high safety standards thus are reliable. They do not fail in any conditions where lubricant spills, high temperatures or excessive overload.

When using them, it tends to cost effective in the long run. This is because they do not required regular check or maintenance because they are well equipped to handle such rough conditions. They also do not give in to the vibrations that would eventually lead to loose of other machine parts being protected that can be expensive and hard to find. Therefore, by not loosening help keep the machine intact.

There is not a major difference between the normal fastener working mechanism from the vibration resistant one. They both employ the use of a threaded nut and a bolt. The only difference is the ability to resist vibrations or shock. Therefore, they can be used in any part of a machine and still work like a normal bold. They normally are also versatile as they can be re used in the same place they taken from because they normally are not destroyed during dissemble like in rivet joints.

They are simple to install since some of them put the vibrations into good use. Some of these engineered bolts and nuts use vibration to tighten and lock themselves into position. They normally are therefore simple to put in as long as you get the bolt and the nut loosely tightened up, the vibrations themselves tighten the two.

Some shock-proof fasteners help protect the materials or parts they normally are joining together. They do so by absorbing the shock. They may be spring like or have a soft part in them that helps dampen the vibrations and protects the materials from cracking or tearing due to the rapid contraction and expansion at high frequencies.

The shock proof fasteners are usually made of many designs, sizes and each fits a specific need. Examples are using spring washers to dampen the shock, use of safety wires among many other ways to resist vibrations. One can therefore choose from the most effective and applicable way to reduce the vibrations negative effects.
