  • Good bolts
Size: 1/2 x 6
Combo package of bolts, nuts and washers.

  • Darn sturdy carriage bolts
Size: 1/2 x 8
I have a post that needs to go through two 2x8s, and I could have prob used a 6 inch bolt, but I opted for the 8 inch just to give myself plenty of space to work. Well, this bag of 8 inch bolts weights a load, so do some stretches before you try to pick it up. The bag itself is thick plastic and didn't break in shipping. The nuts are in a small bag inside. I used my 1/2 paddle to drill the hole and 3/4 near the top to give some room for the head support. Yep, I split the 4x4 in my picture. This is me learning woodworking. But I have additional brackets to reinforce it for installation. I haven't used any other carriage bolts before, so I can't compare. But these are getting the job done for me. They are the size described and the nuts fit. ... show more

  • Galvanized bolts.
Size: 1/2 x 10
Galvanized bolts that cost less than big box stores. Seams to be good quality and fit between bolts and nuts wasn't as loose as some that I have used in the past.

  • Beefy!
Size: 1/2 x 10
I got these to use to replace some 2x8 cross bracing on the 8x8 pilings under my house. These fit perfectly with a little left over and having the nuts, bolts and washers all together made the job super simple. Definitely happy with these bolts, and even though I only needed 16 of them, it's nice to know I've got some spares for other projects. Highly recommend! ... show more

  • Maker Bolt? Yes Please
Size: 1/2 x 10
These guys make great hardware. I think I've only managed to snap the head off of 1 bolt by Maker and that was pretty unfair of me to assume I could drive something in with an air impact and no pre-drill. Cost per unit is nearly unbeatable for the reliability for just about everything Maker bolt makes. These bolts were no exception. ... show more

  • 10 inches of quality bolts.
Size: 1/2 x 10
Everything i have gotten from Makers Bolt has been good quality. Got these for a future project I will be doing on the barn. everything threads well the finish is a bit scuffed from shipping but its a bolt what do you expect.

  • just like the hardware store
Size: 1/2 x 6
These galvanized bolts are the same exact quality as the one from your hardware store. If anything these are better because it this has a washer and nut. These two additional item are galvanized as well. You get more value by buying all three items.

  • Pretty Decent -- Time Will Tell
Size: 1/2 x 8
The galvanizing on some of the bolts and, especially, the hex nuts, seems to have been worn due to handling and, possibly, transit. I have placed samples outdoors, in a damp environment, in order to evaluate this potential issue. Otherwise, the bolts and nuts thread together properly and the washers have the same dimensions as other 1/2" flat washers. The bolts are threaded over about 90% of their lengths. Meaning they can be used instead of shorter bolts provided there is room for the excess bolt length. ... show more
