ASTM A193
Scope
Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

Build your own exterior windshield sun screen to help keep the sun’s heat out, but still provide some visibility from inside the boat’s cabin. These exterior mesh vinyl fabric shades have the added benefit of giving you privacy* while your boat is moored. Even though you can see through the mesh fabric from inside the boat’s cabin, people on the outside cannot see through the mesh fabric. Block the HEAT, not your VIEW!
In this video we will show you how to pattern for the shades, sew a facing & binding on the edges and then how to install snaps and adhesive snap components called YKK Snads to the boat (a no drill solution for a snap stud).

* NOTE – The visibility through the screen is always determined on the side of the screen which has the least amount of light. For example; At night if the lights are on full power inside a boat’s cabin the people on the outside will see silhouettes of persons inside the boat’s cabin.
