Carriage Bolts
Carriage bolts commonly have a smooth, domed head with a square section underneath that is pulled into material to prevent spinning during installation. This allows the bolt to self-lock when it is installed through a square hole in metal straps, or a round hole in most woods. It can be installed using a spanner or a wrench.
Depending on your application, we supply a wide array of materials and grades, such as hot dipped galvanized carriage bolts, Grade-5 and Grade-8 carriage bolts for greater load carrying capacity, or 316 stainless steel carriage bolts for greater corrosion resistance.
