M4 x .7 x 15mm Rubber Well Nut by Dress Up Bolts
Well nuts give you the freedom and protection to secure pieces in hard to reach places that prevent you from using a normal nut. You just have to place the well nut through the opening and screw your M4 bolt-in causing it to compress and tighten.
- Well Nut requires an 8mm (5/16") hole
- Torque Specs: 3 lb-IN
