Product Description

ASTM A193M Class B8M Stainless Steel 316 Heavy Hex Bolts ASME/ANSI B18.2.3.3M Hex Heavy Screws

 

Product Descriptions:

 

Made from 316 stainless steel, these Grade B8M screws are more corrosion resistant than 18-8 stainless steel screws and have excellent resistance to chemicals and salt water. They may be mildly magnetic. Also known as pressure bolts, these screws meet the high-pressure and high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges.

Length is measured from under the head.

Screws should be used with Grade 8M nuts.

 

Mechanical Requirements:

 

Class B8M
Heat treatment Carbide solution treated
Tensile strength 515Mpa min.
Yield strength 205Mpa min.
Elongation 30% min.
Reduction 50% min.
Hardness 223HBW max.

Product Features:

 

Heavy Hex Screws Series should be used for nominal body diameters of 1-1⁄4 in [30 mm] and less.

For larger sizes, the Heavy Hex Screw Series should be used, except the maximum body diameter and radius of fillet may be the same as for the Heavy Hex Bolt Series.

The body diameter and head fillet radius for sizes of Heavy Hex Cap Screws and Bolts that are not shown in their respective tables in ASME B18.2.1 or ASME B18.2.3.3M may be that shown in the corresponding Hex Cap Screw and Bolt Tables respectively.
