Final answer:
The snap fastener installation press that is used as a last resort is a manual hand press.
Step-by-step explanation:
The snap fastener installation press that is used as a last resort is a manual hand press. This type of press is typically used when there are no other options available or when other methods have failed.
While the manual hand press may not be as efficient or precise as other types of presses, it can still be used to install snap fasteners in situations where automated or powered presses are not accessible. It requires manual force to operate and may take longer to complete the installation process.
