Zoro Select 29NH37 Lag Bolt for Concrete
The Zoro Select 29NH37 is a 6 in steel lag bolt intended for securing parking curb stops and speed bumps to concrete surfaces. It is designed for contractors and facility managers who need a direct fastening method for traffic-calming hardware.
Installation limited to concrete mounting surfaces
This fastener requires a concrete installation surface and is not rated for asphalt, wood or other substrates. The 5/16 in height and 7/8 in width define the bearing area, so the drilled hole and anchor must match these dimensions for proper load transfer.
Straightforward drive-in installation
The bolt installs with common impact or hand tools into a pre-drilled concrete hole. Misalignment or an undersized hole are the most frequent causes of reduced holding power or bolt damage during installation.

Questions about this item
Which lag bolt length matches the 6 in dimension shown for the 29NH37 model?
The 29NH37 is the 6 in lag bolt; other part numbers in the compatible list such as 29NH30 through 29NH36 and 29NH38 through 29NH42 correspond to different lengths or variants.
What does the 6 in length mean when the bolt is installed in concrete?
A 6 in steel lag bolt driven into concrete provides roughly 6 in of embedment for anchoring parking curb stops or speed bumps securely.
What installation surface and diameter does the 7/8 in width imply for this lag bolt?
The 7/8 in width is the head size for driving the bolt; the product is specified for concrete installation surfaces and uses a standard lag thread for that material.
