§ How it works

The drive sits inside.

  1. 01Admire the aesthetics.A head that finishes level with the surface. No recess, no socket, nothing to see.
  2. 02Hidden standard T-drive revealed.Press a 6-lobe bit to the head and the captive plunger gives way to expose the drive.
  3. 03Retains normal function — screw it in.Full torque through a standard recess, with the same tools you already own.
  4. 04Admire the aesthetics again.Lift the bit and the plunger returns. The surface closes behind it.
Flush Fasteners® · Est. 2022

A fastener should serve the surface, never interrupt it. We engineer hardware that holds the line, holds the tolerance, and holds its place out of sight.

A conventional countersunk screw leaves a cone-shaped recess and a drive socket open to the world. That is a place for water, dirt and bacteria to sit, and a break in every line the designer drew. A Flush Fastener finishes level: no recess, no crevice, no protrusion. The same fastening strength, and a surface you can run your hand across without finding it.

Marine fastenersFor the water.

Salt-spray tested to 500 hours. Brushed finish. Marine-grade 316 stainless with zero surface discontinuity, because every interruption is a place for corrosion to start.
