About this item
- CARBON STEEL CONSTRUCTION: Built with a carbon steel body and center pin, these concrete anchor bolts serve as carbon steel concrete fasteners for mounting hardware on concrete surfaces.
- CLEAR NOMINAL SIZE: Each concrete bolt is labeled 3/8 x 3-1/2 inches, making the selected size easy to verify before use in concrete or cement fastening projects.
- CENTER-PIN EXPANSION: The hammer drive pin anchor format expands the body inside concrete or cement, giving these expansion anchors a mechanical fastening point for the attached fixture.
- CONCRETE AND CEMENT USE: These cement anchors suit industrial concrete fastening, building maintenance, repair, and household projects on concrete or cement bases.
- 20-PIECE PACKAGE: The box contains 20 drive pin anchors in one matching nominal size, supplying a single-size set for projects that require multiple anchor points.
