When you need to fasten something to cement concrete masonry, you can drive a mechanical screw straight into the material, or you can set a fastener in an epoxy adhesive. These two approaches solve the same general problem but work very differently.
Quick verdict
Choose the epoxy adhesive when your job is about anchoring into concrete, block, or masonry and you want a bonding material that goes in as a paste. Choose the screw set when you prefer to twist a mechanical fastener directly into masonry, brick, block, cement, or stucco and be done without waiting for a cure.

Where each product wins
- Epoxy adhesive: The PC-Concrete cartridge is a paste that can anchor threaded rod into cracked and uncracked concrete, repair cracks, and fill vertical or overhead cinder block voids without dripping or sagging. It is specified for concrete, grout-filled block, and masonry.
- Concrete screws: The screw set uses a Torx recess to reduce the chance of bit slip, and the Ruspert-coated 1022A carbon steel is positioned for indoor and outdoor use. A T30 star bit and an adaptable drill bit are included.
Product notes
8.6oz Epoxy Adhesive for Concrete Anchoring & Repair
This PC Products cartridge pairs anchoring with repair in one gray paste. It can set threaded rod into cracked or uncracked concrete, repair cracks in floors and walls, and fill overhead cinder block voids without the mix sagging or dripping. The paste works on concrete, grout-filled block, and masonry, and the full cure time is listed at 4 hours. That cure time is the main trade-off: you are planning around a wait rather than driving a screw and moving on. The 8.6 oz container is the adhesive, and the product is built for jobs where the concrete condition is part of the task. If you are anchoring into sound material and also need to repair a crack nearby, this cartridge can handle both.
1/4" x 2-1/4" Concrete Screws, Anchoring to Masonry, Brick, Block, Cement or Stucco (30PCS)
The concrete screws use a Torx drive instead of a Phillips head, which helps prevent bit slip when driving into hard substrates. Each fastener is the listed 1/4-inch by 2-1/4-inch size, and the 30-piece pack gives you plenty of spares for a job. The 1022A carbon steel body has a Ruspert coating for corrosion resistance, and the package includes a T30 star bit and an adaptable drill bit. The limitation on this option is that it only does mechanical anchoring. There is no adhesive or filler here, so cracks and voids are not part of the job it can solve. For direct attachment to masonry, brick, block, cement, or stucco, this is a straightforward lower-listed-price path.
Final choice by use case
For anchoring bolts or threaded rod into concrete with an adhesive and repairing the surface material at the same time, the epoxy adhesive is the more complete package. For direct fastening into masonry, brick, block, cement, or stucco with a mechanical set, the concrete screws are the easier match.
