When installing rivnuts, what is a common consideration?

When installing rivnuts, pre-drilling accurate hole sizes is essential because it ensures that the rivnut can properly fit into the material without causing damage or misalignment. Proper hole size is critical for the rivnut to grip firmly and create a secure connection. If the hole is too large, the rivnut may not hold securely, and if it is too small, it may not fit at all, leading to installation difficulties.

This consideration is particularly important in sheet metal applications, where maintaining the integrity of the material is essential for both strength and performance. Ensuring the correct hole size helps to avoid complications such as structural weakness or the rivnut pulling out under load. Therefore, the accuracy of pre-drilling contributes significantly to the effectiveness of the fastener installation, making it a common and critical consideration in the process.
