Jergens Heavy Duty Industrial Style Keylocking Inserts are used to quickly repair stripped, damaged, or worn-out threads. They are also used in original equipment where they strengthen threads in soft metals like magnesium or aluminum. Our threaded inserts are easy to install and remove. No specialty drills, taps, or pre-winder tools are required. The keys are driven down into the threads of the surrounding base material, locking the insert in place.Features, Benefits, & Product Specifications:Insert Materials & Finishes:Carbon Steel (C1215 or Equivalent), Parkerized303 Stainless Steel, PassivatedKey Material: 302 Stainless SteelTolerances: ±0.010 for Inch, ±0.25mm for MetricInserts with internal thread size of 5/16-18 or larger are furnished with (4) locking keysSpecial materials, sizes, and Mil-Spec available upon requestRoHS compliantNote(s):Install insert 0.25mm to 0.76mm below surface and drive locking keys down.
