DIN603 A2-70 Stainless Steel Screw Square Neck Carriage Bolts

Product Description:

A2-70 Stainless Steel Screw Square Neck Carriage Bolts

They're a good choice for ACQ-treated (arsenic-free) lumber.

A square neck keeps them from turning when tightening a nut.

A smooth, rounded head provides a finished look.

Length is measured from under the head.

DIN 603 is functionally equivalent to ISO 8678 with slight differences in head diameter, head height, and length tolerances.
