Overview

• Spin-Drive (thread forming) fittings have special tapered drive threads for fast production line installation in untapped holes to save tapping cost
• Spinning into the hole with a power wrench provides the most effective installation
• Installation torque limits, to avoid stripping, should be established by test in the type of material in which production fittings are to be installed
• Installation force causes a rearrangement of mating material to conform with the fitting thread contour creating a leak-tight permanent seal
• Not recommended for heat-treated parts
• Fitting threads are heat-treated to Rockwell 83-89 on the 15N scale
• For field servicing, Spin-Drive fittings may be replaced by any standard fitting having the same thread size or another Spin-Drive fitting
