Spit Fast Hammer Screw Anchor
Hammer screw anchor for fixing to concrete. Pre-assembled, demountable, quick through fixing.
• Wide collar - Ensures tight fixing
• Through fixing - Lowers in place cost
• Fast installation
• Zinc plated drive screw - For corrosion resistance
By hammering in the fixing, the drive nail pushes against the pre-expansion collar until the sleeve is fully located. Further hammering or tightening the screw causes the sleeve to expand. When point of contact is made in the hole the screw is drawn in towards the fixing until flush with the fixture surface.
• Drywall track and brackets
• Battens / sole plates
• Metal frames
