Knurled area acts as setting guide.
Fully sawed expansion slots.
Broaching edges insure undercutting of hole.
Exclusive undercutting ring.
Foot on expander plug keeps hole clean and assures full expansion.
Vibration-proof, heavy duty anchors where circum- stances make pre-drilling the choice. Unlike lead anchors and friction types, RED HEAD Non-Drilling Anchors are all steel and actually undercut the bot- tom of the hole.
