Fastener Material Selection

There is no one fastener material that is right for every environment. Selecting the right fastener material from the vast array of materials available can appear to be a daunting task. Careful consideration needs to be given to strength, temperature, corrosion, vibration, fatigue and many other variables. However, with some basic knowledge and understanding, a well thought out evaluation can be made.

Grades & Sizes

Metric Fasteners come in many grades & sizes. Fastener Grade (US) or Class (metric) refers to the mechanical properties of the fastener material. Generally, a higher number indicates a stronger, more hardened (but also more brittle) fastener. Our handy charts can help you find the metric fastener you need for your application.

Tensile Strength

The most widely associated mechanical property associated with standard threaded fasteners is tensile strength. Tensile strength is the maximum tension-applied load the fastener can support prior to its fracture. This table below looks at Tensile Strength of Fasteners by Class. The higher the class, the higher the tensile strength.
