What Are Fastener Mechanical Properties?
Fasteners are arguably the most commonly used connecting items. You can find them anywhere you look. They hold your house, toys, car and just about everything else together.
When dealing with the many kinds of fasteners available, it is critical to deal with all of the components of fasteners. But just what is tensile strength? What about shear load? Join us as we dive deep into understanding fastener properties and discover what these industry terms mean.
|Tensile Strength||Refers to the maximum load under tension a fastener can handle before being compromised.|
|Tensile Load||Refers to the maximum load (pressure in tension) exterted by the installation material against the fastener before it will compromise.|
|Ultimate Tensile Stress||Refers to the estimated minimum where a fastener will compromise its integrity.|
|Elongation||Refers to the stretching and deformation that will occur to a fastener caused by a load exceeding its capacity.|
|ProofLoad||A test load a fastener MUST be able to hold without causing any compromise in its integrity. Considered the maximum safe load of a fastener.|
|Pre-Load||One of the most important measures in the industry. Refers to the axial load placed on a fastener. Pre-load is considered to be 75% if the proofload.|
|Shear Load||The load a fastener can handle when two materials are pushing against each other onto the fastener. This will vary if the load is pressing against a fasteners shoulder versus it’s threading.|
|Torsional Strength||Maximum torque a fastener can handle before the threading becomes warped or destroyed.|
|Yield Strength||Refers to the load a fastener can handle before begining to stretch.|
|Yield Point||The definitive point a fastener can no longer handle the load before stretching.|
|Fatigue Strength||Fasteners expand and contract many times due to elemental stresses. Fatigue strength is the maximum number of times this can occur in a cycle before some critical component of the fastener becomes compromised.|
|Creep Strength||Refers to a fastener that has heated up and elongated due to the load under pressure and the heat.|
|Hardness||Refers to a fasteners ability to scratch, mar or otherwise damage another material without itself being damaged.|
Now that you know what these terms mean, you can begin using them to help you find the appropriate fasteners for your job.
*Not all fasteners are made equal. Always follow the specifications from where you buy your fasteners to get the best results.
