Modern Carriage Bolts in sizes from #6-32 x 1-1/8" to 3/4" x 24". We do not stock all sizes.

Modern Carriage Bolts have Full Threads (up to 6" long, then a TL = 6" and a reduced shank beyond the threads), and obnoxious Head Marks.

Traditional Carriage Bolts have No Head Marks (or one or two simple marks) and partial threads.

We have begun to Mill Order Traditional Carriage Bolts, and we will add sizes as time and capital permits. Our customers prefer the traditional carriage bolts, so we will stock as many sizes of the Traditional Carriage Bolts, and as few of the Modern Carriage Bolts, as we can. If you don't see the size you need in the Modern Carriage Bolts category, look in the Traditional Carriage Bolts category, it may be there.

Please check individual products for Head Marks, and Thread Length (TL).
