Hollow rivets are also known as Semi-tubular rivets are similar to solid rivets, except they have a hole. The purpose of this hole is to reduce the amount of force needed for application by rolling the tubular portion outward. The riveting process is similar to that of the semi-tubular rivet but holding is weaker because the inner diameter of the rivet is entirely hollow. hellary offers these rivets in different finishing and materials like Steel hollow, Aluminum hollow, Stainless steel, Brass, Copper, etc.
