DrillSpot 1/2"-13 x 10" 18-8 Stainless Steel Round Head Carriage Bolt, Pack of 1000

Carriage bolts are pushed into a hole the same size as the shank and then hammered in the rest of the way, where the square shoulder locks it firmly in place. Used whenever a smooth finish surface is needed so that nothing becomes snagged on the fastener. Stainless Steel material. Grade 18-8 has the same design advantages as a low carbon bolt, however can be used in environments that require greater atmospheric corrosion resistance.
