This M4 x .7 x 15mm rubber well nut is designed to secure components in tight or hard-to-reach spaces where traditional nuts won't fit. It works by inserting the well nut into an 8mm (5/16") hole, then tightening an M4 bolt which compresses the rubber to hold parts firmly in place.

Ideal for makers, woodworkers, and DIY enthusiasts needing reliable fastening solutions in compact areas.

Important details:

  • Requires an 8mm (5/16") hole for installation
  • Recommended torque: 3 lb-IN

Consider pairing with M4 titanium hardware for added durability.
