Q: What does the spec ASTM B164 apply to and can you produce hex heads per this spec? I believe it is for Monel bolts?
A: Monel bolts per ASTM B164 applies to both Monel 400 and Monel grade 405. This specification standardizes the different processing techniques for each of these materials in the form of hot-worked and cold-worked rod and bar, as well as cold-worked wire.
