What to consider before buying

When choosing a set-screw shaft collar, consider the shaft material (steel vs stainless), environment (corrosion risk), and torque requirements. For general use, a steel collar with black oxide finish offers good balance. For corrosive environments, opt for stainless steel. Check bore size and ensure the collar matches shaft tolerance. If space is tight, look for narrow width collars. For high holding force, consider collars with two set screws.
