Drive Rivet Anchors for Block and Brick

Fasten signs, security cameras, and motion detectors. All of these anchors have a rivet head that creates a secure connection with a finished look. Easier to install than other types of anchors for block and brick, the anchors expand as you hammer in the pin or screw. Since the gripping force is distributed along the entire length of the anchor, it won’t crack soft materials. These anchors can be used in concrete near edges, corners, or other weak points, but they are not as strong as other drive rivet anchors for concrete.

To install, insert the anchor through your component and into a drilled hole. Then, hammer the pin or screw until it's flush with the anchor's head, which expands the anchor body.

Pin Drive Anchors

To remove, pry out the pin and then pull out the anchor.

Drive Rivet Anchors for Concrete

Our strongest drive anchors are best for securing objects such as safety railings and warning signs. All have a rounded head that offers a finished look, won’t snag on objects, and is hard to grip, preventing unwanted removal. Often used for permanent installations, you can't remove your object without yanking the anchor out. These one-piece anchors compress when hammered in and expand inside a drilled hole, creating a powerful grip. No tightening is needed, making them quicker to install than wedge anchors.

To install, hammer the anchor through your object into a drilled hole until the head is flush with the surface. The installation force stresses your base material, so avoid using the anchor near edges, corners, or in cracked surfaces.

Zinc-Plated Steel—The most common choice for areas with occasional exposure to moisture.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these anchors won't degrade when exposed to harsh weather, salt water, and most chemicals.

Vibration-Resistant Drive Anchors for Block and Brick

Best for securing heavy machinery with constant motion, such as vibrating feeders and conveyors, to walls and floors, these anchors won’t shake loose. As you hammer in the pin, the anchor body expands while the ridges bite into your hole’s walls for a superior grip. These anchors require more force to install than sleeve anchors, so the block and brick you are installing them in should not be worn or cracked.

To install, position the nut and insert the anchor through your machinery into a drilled hole. Then, hammer the pin until it's flush with the top of the bolt, ensuring the anchor is fully set.

Pin Drive Anchors with Hex Nut

You can remove your machinery by unfastening the nut, but the anchor itself cannot be removed without prying out the pin.

Pin Drive Anchors with Tamper-Resistant Nut

Image of Product. Front orientation. Contains Annotated, Inset. Anchors. Vibration-Resistant Drive Anchors for Block and Brick, Pin Drive Anchors with Tamper-Resistant Nut.

A tamper-resistant nut prevents the unwanted removal of machinery. Turn the nut round side up for a domed look or flat side up to create a flush finish in countersunk holes. Once set, the nut can’t be removed. The only way to remove the machinery is to pry out the pin and remove the entire anchor.

Steel—Best for dry environments since moisture will cause these anchors to rust.

Easier to install than other types of anchors for block and brick, the anchors expand as you hammer in the pin or screw. Since the gripping force is distributed along the entire length of the anchor, it won’t crack soft materials.

Light Duty Drive Rivet Anchors for Concrete

More secure than masonry nails but not as strong as other anchors for concrete, these are often used to mount lightweight signs and control panels. Also known as tap-in rivets, they’re barbed to resist pullout after being hammered into a hole. All have a rounded head for a finished look that won’t snag on objects.

To install, hammer the anchor through your component into a drilled hole that’s slightly longer than the anchor until the head is flush with the surface. The anchor will compress and then expand inside the hole. To remove, pry out the anchor.

Nylon—Strong, durable, and economical. Best for dry environments, these anchors will swell and weaken when exposed to moisture.
