Self-Clinching & Weld Fasteners

Flush Nuts

Clinch nuts that finish flush on both sides of the sheet.

Section: Self-clinching
Type: Nuts

Overview

Flush nuts sit flush on both faces of the sheet once installed. Ideal where nothing may stand proud of the panel on either side.

Full dimensions, preferred lengths and installation / push-out / torque-out performance data are in the tables below, taken from the self-clinching fasteners catalogue.
