Aluminium CD Weld Standoff
Product Details
CD weld standoffs provide a permanent threaded spacer and are ideal for use in applications where perforation of the base material is not desirable such as waterproof enclosures.
Capacitor discharge fasteners have a small pip under the weld end which melts during the arc and welds the end of the fastener to the material, this is assisted by spring pressure from the welding gun. The fast weld times minimize heat buildup, resulting in welds with very little distortion, discoloration or burning. They are often used where appearance is a necessary feature.
