I purchased these bolts over a year ago to secure D-rings on my utility trailer for tie downs. The stainless bolts have held up well over time sitting outside in the weather and have provided a strong point to secure cargo. I do not have any dislikes for this product. Please give a thumbs up if this was helpful.

These bolts were perfect to secure the deck post (4×4) to my deck railing. The post are very secure. Other bolts in the past have broken once tighten. No issues with these bolts. They are very strong.

These Everbilt 3/8 inch x 1-1/2 inch zinc plated hex bolts come in a 25 pack box and are a great value for a general purpose fastener. They are a quality made bolt with a good zinc smooth finish and clean and accurately cut threads. These come in many sizes and the 3/8 inch is a good size for general use around the home or garage projects. I would also pick up zinc 3/8 inch washers and 3/8 -16 nuts to have on hand. The 1 1/2 inch length is a good size and these can be easily cut with a hack saw if necessary.

All bolts worked great for my project! They have a very even and well distributed zinc layer that should allow them to hold up to the outdoors for much longer than plain steel bolts! They were plenty strong to bolt together pieces of 1/4" steel plate and held them firmly. All the bolts i used threaded easily and the hex heads didn't strip, but I was using sockets so that would be a rare occurance as it is.

The EVERBILT 3/8 IN. X 1-1/2 IN. ZINC HEX BOLTS were utilized to connect two rolling tool carts as seen in the included pictures. These are very strong, coarse threaded bolts, 3/8 inch in diameter to be utilized were strong connections are needed to be made. In our case, rolling tool carts are not quite large enough for our projects so, we connect two. This allows for more tool and parts capacity while still maintaining a light and stealthy box. These 1-1/2 inch bolts along with EVERBILT’S 1 inch bolts provided a very strong connection.
