HOW TO APPLY SPEED NUT FASTENERS

FLAT TYPE "U" TYPE
Fastener is positioned over screw clearance hole with screw-engaging prongs pointing up or outward. Screw is started into nut by hand from the underside.
Push into position with thumb until extrusion on lower leg snaps into screw hole. The fastener "floats" in screw-receiving position to correct for normal misalignment in panel mounting holes.

Screw can be power-driven into locked position (when base arch of fastener is flat) or a hand screw driver can be used. No wrench is required, finger pressure will prevent it from turning.

Place second panel in position and drive screw. Access to opposite side is unnecessary. Flush mounting can be made by embossing either panel.
