In strut applications, lock washers are often used in conjunction with hex head cap screws to securely fasten strut channels to other components such as brackets or beams. The use of lock washers in this way helps to prevent the fastener from loosening over time and provides a secure and tight connection between the strut and other components.

Lock washers feature a unique design with a split or helical shape that creates tension between the fastener and the material being fastened. This tension helps to prevent the fastener from loosening due to vibration or other forces.

Lock washers come in a variety of materials including steel, stainless steel, and brass, depending on the specific application requirements. They are also available in a range of sizes to fit the diameter of the fastener and the hole in the strut channel.
