The Hillman Group 5/16 Stainless Steel Carriage Bolt

Stainless Carriage bolts are designed to fasten a wooden face to either a wood or metal frame. The smooth domed head offers a semi-flush low-profile finish to applications where spacing is tight. The square underside of the head is self-locking to eliminate spinning and the need for a driving tool. The stainless steel finish provides superior rust prevention which is excellent for all outdoor applications.
