As we all know, half space center bolt, counter letter nail, lock nut screw and other standard parts are all holes, so the heavier the hole depth, the better? Naturally, it is not. Although different bolt depths are different, they all have their effective value ranges. If they are too deep or shallow, they will immediately damage the product properties.

In the case of designing the bolt engineering drawings, we need to analyze the practical problems deeply and blindly pursue the perfect depth. On the contrary, the double drum aluminum core pulling rivet will harm the actual riveting effect. Generally speaking, the diameter and depth of the bolt are consistent. For example, the bolt depth of rod diameter 4 is usually riveted at 4mm, and the actual effect will be better. If it is too deep or shallow, it will harm the actual effect of riveting. Some customers think that if the hole is deeper, the riveting will become more and more tight. In fact, if the hole is too deep, the thickness inside will be relatively thin, which will damage the tensile strength and reliability of bolts, and cause the actual effect of riveting to decline. In addition, we have to work hard on the cost of expanding the depth of bolts. Some deep bolts even need to carry out secondary production and processing, and carry out drilling, which will greatly increase the cost of bolt manufacturing. Therefore, if there are no unique requirements, we should try our best to control the depth of the bolt hole within the effective range, so that the bolt is not only easy to rivet, but also strong and durable!

Therefore, every time we find that the depth of customer bolts is too deep, we are detailed to inform consumers of the advantages and disadvantages of this, all aluminum color rivets let customers consider themselves! As a technical professional industrial supplies riveting program service provider, our service purpose is to let customers get higher quality bolts at lower cost
