Precision-manufactured to tight tolerances, this M24 x 128mm hex head cap screw exhibits a nominal thread diameter of 24mm and a grip length of 128mm. The head width measures 23mm, providing ample surface area for torque application via standard hex wrenches. Constructed from robust carbon steel, it offers excellent tensile strength, shear strength, and resistance to deformation under significant load. The inherent hardness of carbon steel ensures a long service life and consistent performance across a wide temperature range. This fastener is well-suited for applications requiring high clamping force and structural integrity, commonly found in heavy machinery, automotive assembly, and general construction.
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. Insert the cap screw into the designated hole and begin threading by hand. 3. Tighten using an appropriately sized hex wrench, applying torque gradually until the desired clamping force is achieved.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to stripped threads or fastener failure. | Utilize a torque wrench to apply the manufacturer's recommended torque specification for the M24 size and thread pitch. |
| Using the wrong size hex wrench, resulting in cam-out and damage to the screw head. | Always use a properly fitting hex wrench that matches the 23mm head width to ensure secure engagement. |
