Phillips / Slotted Flat Head Concrete Sleeve Anchors
Flat Head Sleeve Anchors
Sleeve Anchors with a Flat Head & a Phillips / Slotted Combo Drive
Flat head sleeve anchors are used to anchor and secure material and equipment to concrete masonry surfaces. These anchors have a flat head that will sit flush with the surface material after install. This variety of sleeve anchor has a Phillips slotted combo which can be driven by either a flat head(slotted) or Phillips bit. Flat head sleeve anchors require a pre-drilled hole before installing. They are placed inside this hole and then the head is fastened. This results in the exterier sleeve of the anchor expanding for a secure fit.
Sleeve anchors work on the true expansion principle: turning the head of the sleeve anchor pulls the working end of the anchor up through the sleeve, expanding the anchor and causing the anchor to secure itself into the masonry surface.
