Test Products for Torque-Tension & Bearing Surface Tests

Wilson-Garner regularly manufactures and stocks hex-head test bolts for torque-tension testing of locknuts, plating, and adhesive patches. Our test products are manufactured per the specifications of notable organizations such as General Motors, Ford, Chrysler, and USCAR. All test products are completely traceable by lot and certified in areas including material, property class, surface treatment, and statistical process control on threads. We know that consistency is key in torque-tension testing, so we roll the threads on all of our test bolts twice to ensure consistency of threads. Wilson-Garner also stocks square test washers and hex test nuts for a variety of specifications.
