Hammer Drive Pin Anchors (44 Products)

Hammer drive pin anchors, also called nail or pin drive anchors, are used for the semi-permanent installation of fixtures on concrete, brick & blocks. They are formed from a combination of an expander drive pin and an expansion sleeve. The latter is installed inside pre-drilled holes, whereas the former is hammered into the latter to expand itself and ensure a tight fit. Raptor Supplies offers a wide range of hammer drive pin anchors from brands like Micro Plastics, Grainger, MKT Fastening, Power Fasteners and Westward. Their unique design allows them to distribute the attached fixture's weight for holding them securely in most applications.

• Hammer drive pin anchors are offered in a pre-assembled body containing a nail and an anchor.
• They are ideally used in dry or indoor environments.
• These anchors get installed permanently, so care must be taken before fastening.
• After the anchor is set in place, the fixtures being fastened cannot be removed without destroying the assembly.
• The base material hole must be drilled somewhat deeper than the anchor depth / penetration, allowing dust or debris to fall at the bottom of the hole.
• Selected anchors use a nut for custom tightening of the anchors on the anchored surfaces and an attached washer to prevent the nuts from digging into the anchored surface.
• Many of these anchors come in a pack containing multiple pieces for easy operation.
• Grainger hammer drive pin anchors come in steel pin construction and nylon anchor body for chemical resistance, elasticity and structural strength.
• Westward anchors have steel or Zamac pins ideal for tamper proof and durable installations. Selected models of these Westward anchors come with nut & washer assembly for heavy-duty applications.

Q. Where are these hammer drive pin anchors used?

A. These hammer drive pin anchors are used on concrete, brick or blocks. Some pin anchors are suitable only for brick or block applications whereas some are suitable only for concrete. These hammer drive pin anchors can also be divided on the basis of their usability in light to heavy-duty applications.

Q. What is the difference between hammer drive pin anchors, strike anchors and split drive hammer anchors?

A.

• These anchors are used for similar purposes but have some minute differences among them. Hammer drive pin anchors are mostly used for light to medium-duty applications and have an expansion nail & anchor body. Their expansion nail is struck till it becomes flush with the anchor's head.
• Strike anchors are used in medium to heavy-duty applications as in addition to the expansion nail & anchor body, they also have a nut & washer assembly to protect anchors from going inside the holes during heavy-duty operation.
• Split drive anchors like strike anchors are used on hard concrete but do not have an expansion nail as their head is directly hit to tighten them against the fastened material.

Q. How to install these hammer drive pin anchors?

A.

• Drill a hole in the base material surface up to a minimum anchor depth using a hammer drill (preferably greater depth). The diameter of the hole should be equal to the diameter of the drill bit.
• Clean the dust inside the hole properly using compressed air, vacuum or wire brush for proper fastening.
• Alight the fixture to be fastened over the hole and insert the anchor assembly through the fixture into the base material's hole.
• After ensuring that the head of the anchor body is tight against the fixture, strike the nail on its head using a hammer till it is flush against the anchor head.
• This expands the anchor's base and securely holds the concrete.

Q. How to determine the length of the hammer drive pin anchor required?

A. Users can select the required length of the hammer drive pin anchor by adding the fastened material's thickness to the minimum embedment / depth of the anchor inside the base material.

Q. What are some factors that users should keep in mind while installing hammer drive pin anchors?

A.

• A hammer drive pin anchor is not suited for use in overhead applications or damp / outdoor environments.
• The fastened material / fixture should have a hole with a larger diameter than the anchor's diameter for accommodating the anchor's head or nut & washer.
• A hammer drive pin anchor transfers all the forces / stresses to the base material. So, if the installation location of the anchors is too close together, the forces may interact with each other and reduce the anchor's holding power.
• Users should increase the spacing between these anchors when used for applications that face vibrations or shock loads.

Q. What is the difference between hex nut hammer drive pin anchors and mushroom hammer drive pin anchors?

A. hex nut hammer drive pin anchors are designed for heavy-duty applications, featuring an integrated hex nut for secure fastening of heavy loads like machinery and structural components. On the other hand, mushroom hammer drive pin anchors, with their mushroom-shaped heads, are ideal for lighter-duty tasks, such as mounting decorative fixtures or signage, prioritising aesthetics.
