Hexagon head barrel nuts也稱為 hex barrel nuts 或 sex barrel nuts, are specialized fasteners designed to provide a secure threaded connection in applications where a traditional nut may not be practical.
Features of Hexagon Head Barrel Nuts:
-
六角頭 – The head has six flat sides, allowing for easy tightening or loosening with a standard wrench or socket.
-
桶狀 – The body is cylindrical (barrel-like), providing a larger threaded surface area compared to standard nuts.
-
內螺紋 – The barrel is fully or partially threaded to accept a mating bolt or threaded rod.
-
Durable Material - 通常由 steel (carbon or stainless steel), brass, or other metals depending on corrosion resistance and strength requirements.
-
Variety of Sizes – Available in different diameters, lengths, and thread pitches (metric or imperial).
常見應用:
-
家具組裝 (used in knockdown fittings)
-
Automotive & aerospace (for specialized fastening needs)
-
Structural frameworks (for joining metal or wood components)
