Here you can purchase B8M carriage bolts and heavy hex bolt with 100% sample preservation, PMI & wedge tensile testing
What is the main purpose of wedge tensile testing for A193 b8m stainless steel bolts, and how does it differ from PMI testing?

The main purpose of wedge tensile testing for A193 b8m stainless steel bolts is used to ascertain the tensile strength and other important mechanical properties of the bolts.

This method is used to check how much load or force the bolt can withstand using a wedge-shaped grip whereas the PMI (positive material identification) is used to check the chemical properties of the bolts.
