Question

How can a person distinguish a metric fastener?

O a. Grade number on the head
O b. Number of threads per inch
O c. Hash marks on the bolt head
d. Color code on one side

Answer 1

A person can distinguish a metric fastener based on the grade number on the head, the number of threads per inch, and hash marks on the bolt head.

Step-by-step explanation:

A person can distinguish a metric fastener in a few ways:

1. Grade number on the head: Metric fasteners are typically marked with a grade number on the head, such as 8.8 or 10.9, indicating the strength of the fastener.
2. Number of threads per inch: Metric fasteners have threads specified by pitch, which is the distance between threads. It is measured in millimeters rather than threads per inch, as in non-metric fasteners.
3. Hash marks on the bolt head: Some metric fasteners have hash marks on the bolt head to indicate their grade.
