A Higher Standard for Your Everyday Hardware Needs.
Not all basic hardware is created equal. At Vintage Parts Revival, we believe that even a standard carriage bolt should have superior quality. This New Old Stock (NOS) 1/2" x 2-1/2" carriage bolt is a perfect example—a reliable, general-purpose fastener made with the quality and attention to detail that sets it apart from the commodity hardware in big-box store bins.
This is your go-to bolt for a vast range of woodworking, construction, and general repair projects. The classic carriage bolt design features a smooth, low-profile head for a clean, finished look, while the square neck beneath it securely locks into wood to prevent the bolt from turning as you tighten the nut. The bright zinc-plated finish provides a good level of corrosion resistance, making it ideal for indoor or sheltered applications where the hardware won't be exposed to constant, direct moisture.
For projects that demand dependable hardware without the need for heavy-duty galvanization, this NOS carriage bolt offers the perfect blend of performance, quality, and value.
Features & Benefits:
General Purpose Protection: A standard zinc-plated finish provides effective rust and corrosion resistance for most indoor or dry-environment applications.
