Our Metric oval neck track head bolt is engineered for reliable performance in grooved pipe coupling systems. It features a rounded head with an oval neck just beneath, which is slightly larger than the shank diameter. This oval neck securely locks into the corresponding oval slot of the grooved coupling housing, preventing bolt rotation during assembly. The anti-rotation design allows for fast, one-wrench tightening—streamlining installation and lowering labor costs on site.
