Specified by design engineers worldwide, this M23x130mm brass hex head cap screw is manufactured to exacting tolerances. Composed of high-grade brass (typically UNS C36000 or equivalent), it exhibits excellent corrosion resistance to a broad spectrum of chemicals, saltwater, and atmospheric contaminants. Its nominal diameter is M23, with a length of 130mm and a head width across flats of 21mm. This material's inherent non-sparking characteristic makes it crucial for applications in hazardous zones. The mechanical properties, including tensile and shear strength, are carefully controlled to meet industry standards for secure and durable connections.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating threads are clean and free of debris. 2. Apply a suitable lubricant or anti-seize compound if the application requires. 3. Thread the cap screw by hand to confirm alignment and prevent cross-threading. 4. Tighten the cap screw to the specified torque using an appropriate wrench, ensuring the head is seated firmly against the surface.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the brass screw. | Use a torque wrench set to the manufacturer's recommended value to avoid stripping threads or deforming the material. |
| Using the wrong size wrench, leading to head damage. | Always use a wrench that precisely fits the 21mm hex head to ensure proper leverage and prevent cam-out. |
| Installing into improperly cleaned or damaged threads. | Thoroughly inspect and clean both the screw and mating threads before installation to ensure a secure and reliable joint. |
