Product Description
Stainless steel square-neck carriage bolts made of stainless steel 304. These bolts have good chemical resistance and may be slightly magnetic. They are a good choice for ACQ treated (arsenic-free) wood. The square neck prevents them from turning when the nut is tightened. The smooth and rounded head provides a perfect look. The length is measured from under the head.

Feature
Dimensions comply with ASME B18.5 or DIN 603 and ISO 8678 specifications. DIN 603 is functionally equivalent to ISO 8678, but the head diameter, head height and length tolerances are slightly different.
Match the thread pitch of the mating component. Coarse threads are the industry standard; if you don't know the pitch or the number of threads per inch, choose these screws. The fine threads are tightly arranged to prevent loosening due to vibration.
