Stanley Proto's expanded torque screwdriver offerings feature improved accuracy
Stanley Proto has expanded its torque screwdriver offerings with more accurate versions of four existing tools and the introduction of four new torque screwdrivers. The company’s previous offering included four ¼-inch drive torque screwdrivers — an inch-ounce model and an inch-pound model with an accuracy range of ±6% of the torque reading, as well as a CERT version of each. The re-engineered models feature an accuracy of ±4% of the indicated torque reading. This accuracy level is available in the clockwise direction from 20% to 100% of full scale.
The company has also introduced four new 1/4-inch drive torque screwdrivers with a ±2% accuracy (in the clockwise direction from 20% to 100% of full scale). The two new models also include inch-ounce and inch-pound versions.
Torque settings are changed via a metal lock ring allowing micrometer-style adjustments. Each torque screwdriver has a ¼-inch square drive tip, and ships with a 1/4-inch square to 1/4-inch hex adapter for use with insert bits.
