Designed mushroom head style and Pre-assembled a steel nail to be hammered the head for the fast installation to anchor and fix the objects in masonry, concrete brick or drywall,supplied with the full inch and metric mm dimensions.
Zinc alloy hammer drive anchor belongs to the series of medium and light expansion bolts, which is made of high-quality zinc alloy materials. Zinc alloy materials have better oxidation and corrosion resistance than carbon steel materials, and can be used for the installation and fixation of indoor and outdoor concrete, masonry or solid dry wall.
The expansion strength force produced by hammer drive anchor can be transferred to the base course where it is installed. If the anchorage is installed too close, it will cause the influence between the interaction forces, which will lead to the base looseness and reduce the anchoring force. In the expansion anchor industry, the minimum spacing between expansion anchors is ten times of anchorage diameter and five times of anchorage diameter of unsupported edge. When all the regular vibration or sudden impact occurs in the installation site, the installation distance between anchors should be increased to ensure the safety and durability of anchorage.
Before installing hammering type anchorage, the size and installation specification must be considered to ensure that the proper size and length of anchorage is used. Zinc alloy hammer anchors with 3/16"-M5 and 1/4"-M6 are outside diameters and are suitable for concrete, brick and block base materials, but are not recommended for overhead applications.
Sometimes, They are called by zamac hammer drive anchor, they are made of corrosion-resistant zamac alloy and can be used in concrete, block, brick or stone. The installation is simple and fast. During installation, clamp the installation object, insert it into the pre drilling hole, hammer the head of the iron nail until it is nailed into the mushroom head, and the lower end of the anchor body is fully expanded to complete the installation. Nails act as expansion and locking pins, and they are tamper proof. The expander unit is made of zinc alloy with hardened steel nails. Zinc hammer drive anchors can also be used with a stainless steel nail for the special occasions installation.
