Straight Up Solid Extended Screw Mounts For Sink Drain Strainers Built To Last Rust Resistant Copper Hardware Quick Install Thick Granite Or Marble Kitchen Sink Replacement Hardware

Extend sink drain mount screws for thick counters
✔️ Electroplated copper drain hardware 0.43 inch shaft 2.75 tall

These extended mounting bolts attach drain strainers to deep countertops without stripping threads. You typically install them under kitchen basins made from granite, quarry tile patterns, or solid surface stone where standard fasteners get shot. This swap keeps repair jobs handy when old parts wear out.

✅ Electroplated copper body resists moisture damage
✅ Cut deep helical threads grip firmly inside basin holes
✅ Adds reliable clearance for countertops up to two inches thick
✅ Fits exact thread pitch for BOTEMY B9173 and B9174 fixtures

💡 Why do drain extension screws fail on heavy vanities?
Original hardware lacks the grip needed for dense countertops.
- Electroplated plating blocks salt air and sink splashes
- Longer shanks clear thick stone without jamming the base
- Precise bore width prevents cross threading during quick swaps
