About this item

  • Drop-in anchor includes a wedge mechanism to create a secure hold within solid masonry and solid uncracked concrete
  • Anchor consists of a zinc-plated carbon steel body and wedge clip, which expands to secure the anchor in place
  • Meets 2000 International Building Code and 2000 International Residential Code specifications
  • Ultimate tensile strength is 16,500 lb. in 4,000-psi concrete
  • Use one-fourth or less of listed maximum values for safe working loads (as required by local regulations)


The Wej-It PD58 POWER-Drop internally threaded drop-in anchor includes a wedge mechanism to create a secure hold within solid masonry and solid uncracked concrete, and meets 2000 International Building Code and 2000 International Residential Code specifications. The anchor body and wedge clip are made of corrosion-resistant zinc-plated carbon steel. The wedge clip expands within the drilled hole to secure the anchor in place. A safety shoulder above the clip provides support when the anchor is under severe strain. When installed, the anchor does not protrude from the drilled hole, enabling flush anchoring of an object to the mounting surface. The anchor's allowable values may be increased 33.3% for short-term loading in resisting earthquake or wind loads.

The included setting tool is externally threaded and has a washer and nut that can be placed to achieve a desired anchor depth. Once the setting tool has been threaded into the anchor and the anchor has been placed into the drilled hole, a hammer or mallet (sold separately) is used to drive the setting tool downward until the nut contacts the mounting surface. Tightening the nut sets the anchor and releases the setting tool from the anchor. An item can be mounted by inserting a threaded fastener (sold separately) through it and into the anchor.

Anchors provide reinforcement to fasteners installed in materials that are considered brittle or have insufficient hold such as drywall, concrete, brick, and stone. Anchors provide support through methods such as expansion from within or behind the substrate, or insertion of adhesive compounds into drilled holes.

Wej-It Fastening Systems manufactures mechanical and adhesive fasteners for use in concrete and drywall. The company, founded more than 60 years ago, is headquartered in Norwalk, CT.

Just moved, and needed to set anchors for a lift in the new garage/workshop. These are the anchors specified by the lift manufacturer. I've now installed this lift in two locations, plus two others for friends. I used these anchors for all of them.For this installation, 16 anchors are set into concrete under a porcelain tile floor. I've been drilling the holes in the concrete myself for the previous installations, but because of the tile I decided to let a commercial concrete coring company do the drilling this time. A 1" hole is made through the tile, plus an additional 1/8" into the top of the concrete. Then, a 7/8" hole is made in the concrete to a total of 6 1/2" deep. That lets the anchor sit down completely in concrete with no contact with the tile.The anchors set easily using the method described in Wej-It's instructions. The installation depths are adjusted down an inch in consideration of the tile. I add lubrication to the threads on the installation tool (a long bolt...) where the nut is used to draw the anchor up to set it. Otherwise, with straight well-cleaned holes, there was no drama at all setting the enchors.I left K's 4Runner (our heaviest car) on the lift a few inches off the floor for a couple test/observation days. There is no discernable movement. The torque on the bolts is the same as when I initially set the posts, indicating that nothing has moved or stretched. It's now safe for mrs dr bob's hubby to use the lift.

These looked like the identical anchors for the MaxJax, BUT the bolts are not cross usable as these are SAE 5/8 bolts, but maxjax uses metric m16 bolts, it looks like it fits, but threads are completely different. Product itself worked an awesome tho.

Good replacement anchors. The washer they give you as part of the installer tool (aka bolt) is useless. You will need a thicker washer. Otherwise good.

Same exact ones maxjax used on the old mx6 model. Not metric.

The quality seems good, however I had to return because half of the parts were missing.

Good product for a light load but not ideal for anchoring a hydraulic jack to lift the car.

We needed an anchoring system that would allow for the removal and storage of an ornamental iron fence at a new hotel each winter. These anchors were the perfect solution for an unusual problem. We will use again.

These were hard to find and work great. Used them to mount a 6,000 lb two post hobby car hoist and it so nice to remove the post when not in use and not have the studs sticking out of the concrete.
