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.
