A Leader in Innovation
Precision Instruments was incorporated in 1938 to pursue the manufacture of the first torsion bar dial type wrenches. Central to the very first patent, awarded five years later, were the tenants of accuracy, reliability, and durability that have become synonymous with the Precision Instruments name. Over the next 24 years, the company would refine and elaborate on the torsion bar dial type wrench with advances that include increased accuracy and signaling options.
From the invention of the torsion bar dial type wrench and split-beam click wrench, to the most reliable micrometer adjustable click wrench, Precision Instruments has always been a leader in innovation.

Three Generations

In 1938, K.R. Larson started on a journey to manufacture a better torsion bar dial-type wrench. 75 years later, his spirit of innovation, determination and commitment to precision live on at our company, Precision Instruments.
Today, our family and everyone at Precision Instruments continue to design and manufacture accurate, reliable and durable torque  wrenches for customers around the world. Thank you for being a part of our journey.
