The Model HS is a highly reliable direct-action hydraulic load cell instrument designed for use with high-strength bolts through 1-1/2" size. Direct dial readings to 170,000 pounds of bolt tension within 1% accuracy show the preload delivered. Recommended minimum bolt tensions are plainly indicated on the gauge face. It can be clamped to a convenient column or bench.

The Model HS is also available with interchangeable bolt bushing and plate sets for each size bolt to be tested in a complete range through 1-1/2" bolt sizes. Adapters can be made for special applications.
