Round head carriage bolt with an integrated square neck that seats into the receiving hole to prevent the bolt from turning during tightening. The smooth, domed head presents a low profile to reduce contact with finished surfaces and handling.

Commonly used for guardrail, furniture, cabinets, wooden structures and frame assembly. Half-thread and full-thread versions are offered, and a range of sizes and surface treatments is available on request. Please confirm required thread length, size, finish and other specifications before ordering.
