The Metal Hit anchor consists of a cylindrical zinc alloy body and a zinc plated steel pin expander. The shank, from the bottom up, is split a major portion of its length. The anchor body has a bore which runs through the head thickness and into the shank for a depth just beyond the point where the slot terminates in the body. The steel pin expander is made of high carbon steel, properly heat treated, and heavily zinc plated for maximum corrosion resistance. TECHNICAL INFO Approvals: Meets G.S.A. specifications FF-S-325, Group V, Type 2, Class 3. Applications: Light to medium duty in concrete block and brick. Installation: (1) Drill hole in base material equal to diameter of anchor being used. Hole depth should be at least 1/4" deeper than the anchor embedment. (2) Clean out hole of all dust and shavings. (3) Insert Metal Hit Anchor , slit end first through material to be fastened and into hole. The bottom of the head must be sitting flush with the fixture plate. (4) Hammer nail flush into head of anchor body. The Metal Hit Anchor is now set. Anchor Length: Thickness of material to be fastened plus minimum embedment plus 1/4" equals anchor length. Anchor Spacing: The forces on a Metal Hit Anchor are transferred to the material that it is installed in. If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the holding power of the anchor. As a rule of thumb, the expansion industry has established a minimum standard of ten (10) anchor diameters for spacing between anchors and five (5) anchor diameters from an unsupported edge. When vibration or sudden impact are part of the load condition anchor spacing should be increased. SIZE DRILL BIT MINIMUM EMBEDMENT PULL-OUT Values shown are average ultimate values and are offered only as a guide and are not guaranteed. A safety factor of 4:1 or 25% is generally accepted as a safe working load. Reference should be made to applicable codes for the specific working ratio. Minimum embedment for satisfactory anchor performance is 4-1/2 bolt diameters. Deeper embedments will yield higher tension and shear capacity.
