1/4-20 Architectural Bolt – Knurled Brass Barrel, Truss Head, Phillips Flat Head Screw, 1-9/16” Length, 55,000 PSI Tensile Strength

About This Product

This is a specific type of hardware bolt often used in furniture, cabinetry, and door hardware – it’s called an architectural barrel bolt or sex bolt. It consists of a knurled brass barrel (about 3/8” diameter, 1-9/16” long) and a matching Phillips flat head screw (truss head style). The thread size is 1/4-20, and it’s made from brass-plated steel with a plain finish. The barrel has internal threads that the screw fastens into, creating a clean, flush look when assembled. The knurling provides a good grip for hand-tightening. Tensile strength is rated at 55,000 PSI with a Rockwell hardness of B60. It’s commonly used to join two panels where you want a smooth finish on both sides, like in display cases, architectural models, or certain types of door hardware. If you’re working on a project that requires this specific fastener, make sure the dimensions and thread match your needs. Sold as a single bolt-and-screw set. A niche but essential item for woodworkers, furniture makers, and restoration enthusiasts.
