Oct 24, 2014 · @Dave- Many fastener grades require head markings that will also indicate the chemistry. Examples of head markings for 300 series stainless are ASTM A193 A320 B8 (304) or B8M (316) which are marked B8 B8M respectively. There is also ASTM F593 which has many several head markings that all indicate 300 series stainless.Fasteners How to Identify Stainless Steel With bolts, stainless steel can be identified by the head marking. These markings indicate steel grade and tensile strength. When installed, stainless steel screws and bolts are known for their longevity. Again, the resistance to corrosion makes the material a recommended choice for construction within 5km of the ocean, and lowered stainless steel bolt head markingsHex Bolt Identification, Markings and Strength Chart Table stainless steel bolt head markingsHex Bolt Identification, Markings and Strength Chart. Additonal information on bolts is located at the bottom of the webpage. Note Some bolts share identical head identification and have significantly different strengths.

How to Identify Stainless Steel Bolts and Head Markings

What are some common head markings on stainless steel bolts and screws? If you look at the head of a stainless steel fastener, you might see a marking stamped onto the surface. These marks hold valuable information about the fastener and learning how to read them can help you decide if its the correct product for the job. In the chart below are the most common head marks found on Anzor's Marking of stainless steels screws and nuts Bossard GroupOther types of bolts and screws can be marked in the same way, where it is possible to do so and on the head portion only. Additional marking is allowed, provided it does not cause confusion. Fasteners that do not fulfil the tensile or torsional requirements because of the geometry may be marked with the steel grade, but shall not be marked stainless steel bolt head markingsMetric Bolt Grade Markings and Steel Strength Chart stainless steel bolt head markingsHead Markings Metric Bolt Class Mechanical Properties Proof Load (MPa) Min Yield (MPa) Min Tensile Strength (MPa) Class 8.8 Medium carbon steel, quenched and tempered 580-600 640-660 800-830 Class 10.9 Alloy Steel, quenched and tempered 830 940 1040 Class 12.9 Alloy Steel, quenched and tempered 970 1100 1220 A2 Stainle
