Purchase Concrete Metal Hit Anchors
Technical Information:
The
Metal Hit Anchor is a precision die-cast, light-duty concrete
anchor combining unusual toughness and remarkable strength.
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.

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.

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.
