Trusted by engineers across multiple sectors, this M13 x 124mm Hex Head Cap Screw boasts a nominal diameter of M13 and a substantial 124mm length, ensuring deep thread engagement. The robust 304 stainless steel composition provides superior corrosion resistance, particularly in harsh or humid environments, and offers a good balance of strength and ductility. The 20mm head width facilitates secure torquing with standard hex wrenches or drivers, making it ideal for structural assemblies, machinery, and outdoor infrastructure where reliability is paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate wrench or socket size for the 20mm hex head. 2. Thread the cap screw by hand for at least two full turns to ensure proper alignment and prevent cross-threading. 3. Tighten the cap screw to the recommended torque specification for the M13 thread size and material, utilizing a torque wrench for precision.
