These screws are specially tempered to meet ASTM A193 specifications for temperatures up to 1100° F. They can be used in high-pressure applications. Length is measured from under the head.

Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.
