All grades and classes of all types of Carriage Bolts (aka Shaker Screws) are manufactured at TRAMEC Hill Fastener. Originally used for assembling carriages, they are used for more versatile purposes these days. Whatever the use, we can make them to standard (ASME B18.5) with short square, long square and fin and rib-necks. Or, you can challenge us with a print of your own. Most of the Carriage Screws we manufacture are made-to-order, and highly customized.
Give us your desired dimensions, hardness and finish, and we will give you a price on a domestically produced Carriage Screw that will meet your requirements. We manufacture 1/4” to 3/4” (M6-M20) and up to 7” (175mm) in length.
