SKU CH-27HT-RHET8

Screw-in stainless-steel shower drain cover with 85.7 mm hole centres, 101.6 mm outer diameter and 1.8 mm thickness for high-flow drainage

  • 10 mm drainage hole gives high flow rate
  • 7 mm screw centres fit standard 10-24UNC fixings
  • 6 mm outer diameter covers 4 inch openings
  • 8 mm 304 stainless steel resists deformation
  • Screw-in installation secures cover firmly in place

Screw-In Round Drain Cover

This black drain cover is a direct replacement for shower, kitchen, balcony and floor drains. It installs with four 10mm screws on 85.7mm centres and fits a 101.6mm outer diameter opening. The 1.8mm thick 304 stainless steel construction resists deformation under regular foot traffic. A 10mm central drainage hole provides a high flow rate for quick water removal.

Suitable For Standard Screw Centres

The cover suits installations where the existing screw holes measure exactly 85.7mm centre-to-centre and the opening matches the 101.6mm outer diameter. It will not fit snap-in or push-fit drain bodies, nor openings with different screw spacing. Buyers who cannot verify these exact dimensions should look at alternative drain covers that match their specific hole pattern.

85.7mm Screw Hole Centre Measurement

The single specification that decides fit is the 85.7mm centre-to-centre distance between the screw holes. Measure the existing drain body before purchase; if the spacing differs, this cover cannot be secured. The 101.6mm outer diameter and 10mm drainage hole are secondary checks, but the screw centre dimension is the decisive factor.

Highlights

  • 7 mm screw centres fit standard 10-24UNC fixings
  • 6 mm outer diameter covers 4 inch openings

Questions about this item

Will the 10-24UNC screws or the 1.8mm 304 stainless steel cover need replacing first?

The 1.8mm 304 stainless steel cover resists deformation and corrosion, so the 10-24UNC screws are more likely to need replacement if they strip or corrode over time.

What limits drainage when the 10mm hole runs continuously?

The 10mm drainage hole diameter sets the maximum flow rate; sustained heavy water volume can exceed this capacity and cause backup.

Does the 1.8mm 304 stainless steel become hot or noisy under all-day water flow?

The 1.8mm 304 stainless steel conducts heat quickly but stays near water temperature, and the screw-in fit prevents rattling during continuous use.
