Product overview
Stainless grade, class and nut pairing are separate controls
Grade B8M and Class 2 must be ordered together with the governing ASTM edition. A generic stainless description does not define the required composition, condition, properties, marking or permissible size range.
Nut material, thread surface condition, lubricant or anti-galling treatment, cleanliness and service environment must be specified separately. XHT does not infer compatibility from appearance alone.

Technical control
Use the governing document—not a catalogue assumption
ASTM A193/A193M covers both alloy and stainless bolting, but Grade B8M, Class 2, matching nuts and service compatibility are not interchangeable labels. The purchased edition and project specification control the exact requirements.
Applications & supply
Options matched to the assembly requirement
Application examples guide the RFQ. Suitability must be verified for the actual connection, service environment and governing specification.
02
Flange assemblies
Stud, nuts, lubricant and tightening procedure treated as a system.
03
Process equipment
Cleanliness, marking and documentation agreed before order.
04
