The offered tube fittings are typically used to spread the load of a strung clasp, such as a screw or nut. Various applications include spacer, spring, wear cushion, preload indicating device, locking device, and vibration reduction. Provided fittings often have an outward breadth that is approximately double their internal breadth. However, this can vary widely. Our tube fittings are frequently made of metal or plastic. Excellent darting joints require solidified steel washers to avoid pre-stack loss due to brinelling after the torque is applied.
