Spit Fast Hammer Screw Anchor
A pre-assembled through fixing anchor to concrete
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.
Sleeve: polyamide 6 is resistant to weathering, ageing and rotting. Withstands temperatures from -20C to +60C. It has good electrical insulation properties. It has high tensile and compressive strength and is largely resistant to chemical attack.
Screw: zinc plated.
Drill a hole through the part to be fixed according to the diameter of the fixing, blow out dust. If the fixture thickness is less than the maximum given in the table below, the hole depth has to be increased accordingly. THEN EITHER Insert the anchor by hand as deep as possible. Tap on the expansion nail to obtain the complete setting of the anchor and until the head of the nail comes into contact with the flange of the sleeve. Or Inserting the anchor by hand until contact of the flange with the part to be fixed. Expand by screwing with a screw driving machine and suitable pozidrive bit.
