Customer Reviews for Crown Bolt 5/16 in. x 3 in. External Hex Hex-Head Lag Screw

Bought a dozen 5/16” x 3” zinc lag screws to bolt a mini split bracket to my wood frame garage wall. I pre drilled for both the treads and the upper shaft. Even with pre-drilling, the lag screws kept breaking with minimal torque. I had to relocate the bracket due to the broken off screws in the wall. I bought stainless screws elsewhere to finish the job and had no problems.

The lag bolts available at Home Depot are poorly made Chinese junk. Since the project I was completing was not critical, I used these anyway as a matter of convenience. Of the 4 bolts I bought, one did not even have a fully formed tip.

The crown bolts worked great for anchoring a header board to studs. It was then used to anchor a sliding barn style door to the header board.

Excellent product and price. The three people that helped me were best of all. I am old and bad health. Will S. , Rashida,and Lori was wonderful help, this is at store 0357 in Baton Rouge, Louisiana

Needed something strong to hold the tool cabinet wheels in place. These babies did the trick but they were thicker than my predrilled wholes could take so I preheated the bolts before installing them. Now my wheels aren't tilting and breaking.

half of them broke going into a 2x4 stud
