For many years, Exafast has routinely and extensively tested critical mechanical properties of our high tensile stock in our own in-house laboratory.
Exafast has invested in state-of-the-art equipment, including:
Instron Satec 600DX Universal Testing Machine - Allowing Proof Load Testing and Ultimate Tensile Strength determination on bolts and proof load testing of nuts.
Future Tech FV700 Vickers Hardness Tester - To allow accurate point determination of fastener hardness.
Kodak Profile Projector - For assessment of fastener dimensional characteristics.
ATM Abrasive Cut-Off Machine and ATM Hot Mount Press - For accurate preparation and mounting of cross-sectional samples for microscopic analysis.
In addition to these state-of-the-art pieces of equipment we have literally hundreds of thread gauges, straightness gauges, vernier calipers and thread micrometers to ensure every dimension is within specified tolerances.
