Review these related topics for this design or route. Grade, treatment, geometry and acceptance remain drawing-specific.
Specify the finished fastener property class, not a strength inferred from the raw grade. Common nominal class references include 8.8, 10.9 and 12.9.
MATERIAL & FINAL CONDITION10B21 is a grade designation, not a finished strength class. There is no single tensile strength that applies to every 10B21 screw.
MATERIAL & FINAL CONDITIONA2/A4 groups and classes such as 70 or 80 describe finished stainless fasteners under the applicable specification. SUS304 or SUS316 alone does not establish A2-70 or A4-80 performance.
APPLICATION REQUIREMENTSCustom threaded components for brackets, equipment modules and other drawing-defined automotive component assemblies.
APPLICATION REQUIREMENTSShoulder, step and adjustment fasteners for guided mechanisms, positioning stations and automation equipment.
