Thanks for the suggestion. eBay is one of my regular go-to places. But no luck at this time.Try ebay.
Thanks for the suggestions. I checked both and found comparable to the HILTI product. But my preference is with HILTI. Just don’t need a box of 50 and can‘t rationalize the $$$ for three bolts.Didn't see any on eBay. Also McMaster-Carr, Fastenal (don't really care for them) or similar suppliers. Why stuck on Hilti? They're not the only game in town. Another option would be threaded rod and epoxy.
