What does NAS bolt mean? “NAS” stands for National Aerospace Standard. The NA prefix is for Metric standards. NAS standards include Part Standards for high strength, precision fasteners.
What is a NAS bolt? NAS bolts comply with the National Aerospace Standard and are commonly used for high technology systems. NAS bolts are necessary for high strength applications and consist of a fine-threaded, dimple headed hex bolt. Material markings for NAS bolts are the same as AN bolt, except they may be either raised or recessed.
How do I identify NAS bolts? How to Measure NAS Bolts
Set the dial calipers to zero.
Measure the overall length of the NAS bolt from under the bolt head to the end of the threads.
Lay the open jaws of the caliper against the threads.
Subtract the overall head length from the thread length.
Confirm the grip by measuring it with the calipers.
How do you read a NAS bolt number? The series number (20004) indicates the bolt class and diameter in sixteenths of an inch (internal-wrenching, 1/4-inch diameter). The letter H before the dash number indicates that the bolt has a drilled head for safetying. The dash number (9) indicates the bolt grip in sixteenths of an inch.
