What is NAS screw?
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.
What is a M1 6 screw?
6 Phillips Pan Head Machine screws. These are made from A2 (18-8) Stainless Steel. Diameter: M1.6 / 1.6mm. Thread Size: 0.35 – Coarse (Standard) Thread.
How do I identify NAS bolts?
NAS bolts have a higher tensile strength (usually about 160,000 psi) and can be identified by a cupped out head. Close tolerance bolts are machined more accurately than general purpose bolts and they are used in applications requiring a very tight fit.
How do you read a NAS bolt number?
The first letters in a bolt number indicate the type of bolt used. This number identifies an NAS close tolerance or internal wrenching bolt. The following number describes the diameter in sixteenths of an inch (7/16). The following letter or absence of a letter indicates the bolt’s material.

What do the letters on bolts mean?
You can usually figure out the grade, or strength, of a bolt by looking at the markings on its head. English bolts (U.S.S. or S.A.E) are categorized by grade, from grade 2 to grade 8, where the grade represents inch strength. The higher the grade, the stronger the bolt.

What are NAS standards?
NAS stands for National Aerospace Standard. The NA prefix is for metric standards. NAS standards include part standards for high-strength, precision fasteners. AIA, in coordination with the Department of Defense, has converted over 500 MIL-specs to NAS.
How do you read bolt numbers?
Whether metric or standard, all bolts are sized by diameter, thread pitch, and length—in that order. So, for example, an SAE 1/2-16 x 2 bolt is ½” in diameter, has 16 threads per inch, and is 2″ long. An M12-1.5 x 50 metric bolt is 12mm in diameter, has a thread pitch of 1.5mm, and is 50mm long.

How do I identify my bolt manufacturer?
Manufacturer’s identification mark, e.g., “X” ( on head of bolts and screws and on one end of studs and stud bolts). Manufacture’s identification mark, e.g., “X”, applied to head (raised or depressed at option of manufacturer).
What is the M in bolt size?
The letter ‘M’ indicates that this bolt uses a metric thread. The number ‘8’ refers to the nominal diameter of the bolt shaft in millimeters. The number 1.0 is the thread pitch of the bolt, which is the distance between threads, in millimeters.
What is M12 in MM?

What does M stand for in bolts?
metric thread
The letter ‘M’ indicates that this bolt uses a metric thread. The number ‘8’ refers to the nominal diameter of the bolt shaft in millimeters. The number 1.0 is the thread pitch of the bolt, which is the distance between threads, in millimeters. And the final figure, 20, is the length in millimeters.
Is M10 a 10mm?
Steel bolt with M10 metric thread. Metric threads are designated with a capital M plus an indication to their nominal outer diameter and their pitch: This bolt is M10 x 1.5 – which means the outside diameter is 10mm and the threads are 1.5mm apart (the most common thread pitch for M10).

What do the letters mean on a bolt?
There are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9. Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher number means the stronger the bolt.
What do the numbers on bolts mean?
The number has nothing to do with the size, but does indicate the relative strength of the bolt. The higher the number, the stronger the bolt. Some metric nuts are also marked with a single-digit number to indicate the strength, and some may have the M and strength grade embossed on the flats of the hex.
