Anchoring into cement, concrete, or masonry usually starts with one question: do you want a chemical bond or a mechanical hold? Epoxy fills cracks and locks bolts into place, while concrete screws bite directly into the base material without mixing. The four options here cover both approaches: a compact syringe, a single epoxy cartridge, a 3-pack of epoxy cartridges, and a 30-count screw set.
Quick take
The single cartridge is the direct one-cartridge option for anchoring and repair. The 3-pack gives you three cartridges when you expect more than one job. The syringe is the compact, low-volume choice. The 30-count screw kit is the no-mix mechanical alternative. The table below shows the listed price for each.

Product notes
8.6oz Epoxy Adhesive for Concrete Anchoring & Repair
At $38.69, this single cartridge sits in the middle of the listed price range. It is built for anchoring bolts, repairing cracks, filling cracks in concrete floors and walls, anchoring threaded rod into cracked and uncracked concrete, and filling vertical or overhead cinder block voids with no drip or sag. The full cure time is 4 hours, and the compatible materials include concrete, grout-filled block, and masonry. The limitation is quantity: this is one cartridge, so a larger job or several anchor points will likely need more than one unit. If you want a single cartridge rather than a multi-pack, this is the product to compare.
PC-Concrete 070086 Light Grey Concrete Anchoring Epoxy Syringe 1.4 oz
The PC-Concrete syringe carries the lowest listed price in this group at $14.61. It is also the smallest volume option, which makes it a reasonable companion for a single anchor or a narrow crack instead of a broader repair. It weighs 0.2 lb, so it is easy to keep near the work area. The practical limitation is the small size: compared with the larger cartridges, it holds far less adhesive, and the syringe format is not the same cartridge format as the larger units. For a small task, this is the low-quantity entry point; for a bigger job, the larger cartridges cover more repair area.
PC Concrete 8.6 Oz. Epoxy (3-Pack
The 3-pack at $54.22 is the highest listed price in this comparison, but it is also the only option with three cartridges. It is a 2-part epoxy kit with a dry-to-touch time of 30 minutes and a brown dry color. If you anticipate multiple repairs or need more than one cartridge, this pack gives you three cartridges in one package. The limitation is that it carries the highest absolute listed price here; if the job is small enough for one cartridge, the single cartridge is the lower-dollar purchase. Use the pack when cartridge count matters more than the one-time purchase cost.
1/4\" x 2-1/4\" Concrete Screws, Anchoring to Masonry, Brick, Block, Cement or
The 30-count screw set at $25.53 is the mechanical-anchor alternative to the epoxy options. The screws are 1/4\" x 2-1/4\", use a Torx drive, and carry a Ruspert-coated finish that passes a 1,000-hour salt spray test. A T30 star bit and an adaptable drill bit are included. The limitation is that screws are size-specific and made for anchoring, not for filling cracks or sealing voids. If the project needs a chemical bond or a crack fill, epoxy is the appropriate category; if you want a screwed-in anchor without mixed adhesive, this kit is the one to consider.
Final recommendation
Use the single cartridge when you want one epoxy cartridge for a mid-size job. Choose the 3-pack when you want three cartridges on hand. Pick the syringe for small anchor points or narrow cracks. Select the screw kit when you prefer mechanical anchoring over epoxy. Let the cartridge count and anchoring method decide which listed price makes sense for your project.
