What it is

The Unicrimp QMS4-16B is an M4 x 16mm slotted panhead machine screw in brass, part of Unicrimp's Q-Crimp fixings range. Brass gives a non-ferrous, corrosion-resistant screw for wiring accessories and general electrical or mechanical fixing.

Signs this part needs replacing

  • Existing screw is corroded, seized or has a stripped slot
  • Screw is missing, or the wrong length/thread for the fixing point
  • Head is damaged and no longer seats correctly

Before you order

  • Check the thread (M4) and length (16mm) match your existing screw
  • Confirm brass is suitable where a non-ferrous or low-magnetic fixing is required
  • Isolate the electrical supply before removing or fitting accessories
