Purpose-built for heavy-duty applications, this M17 x 119mm hex head cap screw boasts a nominal diameter of 17mm and a length of 119mm, with a substantial 31mm head width for optimal torque transfer. Constructed from marine-grade 316 stainless steel, it exhibits exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, making it ideal for environments exposed to saltwater, chemicals, and elevated temperatures. Its high tensile strength ensures secure and reliable fastening in structural assemblies, machinery, and infrastructure projects where integrity is paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Clean both the screw threads and the tapped hole or nut to remove any debris or contaminants. 2. Apply an appropriate thread lubricant or anti-seize compound if recommended for the specific application to facilitate proper torque and prevent galling. 3. Insert the screw into the mating component and engage the threads, ensuring smooth initial engagement. Tighten gradually to the specified torque value using a calibrated torque wrench, referencing relevant engineering drawings or torque charts.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-torquing the screw, leading to thread stripping or fastener failure. | Always use a calibrated torque wrench and adhere to recommended torque specifications for the fastener size and material. |
| Using the wrong size or type of tool, which can damage the hex head and impede proper tightening. | Utilize a properly sized and high-quality hex socket or wrench that fully engages the screw head to ensure even force distribution. |
| Failing to clean threads before installation, potentially causing galling or incorrect torque readings. | Thoroughly clean both the screw threads and the receiving threads to ensure a smooth and accurate fastening process. |
