Nut Inserts
Stripped threads or sheet metal too thin to tap? Nut inserts give you strong threads from one side. Use large flange styles for oversized holes and higher pull-out, thin sheet Nutserts for panels, Tric-Nuts when vibration and torque-out are the enemy and Jack Nuts for specialty blind installs. We keep fractional and metric ready to ship.
