What is the minimum diameter for a hole punch used in inspections?

The minimum diameter for a hole punch used in inspections is 1/4-3/8 inch. This size is specifically regulated to ensure that any holes made during inspections are adequate for securing tags or for other compliance-related purposes. The chosen diameter strikes a balance between being large enough to serve its purpose without compromising the structural integrity of the material being punched. It also aligns with safety standards and practices in automotive inspections, ensuring that any modifications do not interfere with vehicle function or safety systems.

Other diameter ranges might be larger than necessary, potentially risking damage to the components being inspected or creating complications during the inspection process. Hence, adhering to the minimum requirement fosters consistency and quality in inspections while also maintaining compliance with state regulations.
