Key Features & Benefits at a Glance
- Exceptional tensile strength of 150,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from blue-dyed zinc plating extends service life in harsh industrial environments, minimizing maintenance needs.
- High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining thread integrity through repeated use.
- Precision Class 6g thread fit guarantees smooth assembly and secure fastening, reducing installation time and improving joint reliability.
- Partially threaded design allows for optimal clamping force distribution, ideal for applications requiring vibration resistance.
- External hex drive with 36mm head enables easy installation with standard tools, enhancing workflow efficiency on the job site.
- Compliance with ISO 4014/DIN 931 standards ensures interchangeability and consistent quality across global industrial projects.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Class 10.9 metric hex head screws deliver critical performance where structural integrity is paramount. The M24 x 3mm coarse pitch thread configuration provides superior grip in metal-to-metal connections, while the partially threaded shank concentrates clamping force precisely where needed - solving common issues of joint loosening under dynamic loads. The blue-dyed zinc plating offers both visual inspection benefits and enhanced corrosion protection, making these steel fasteners ideal for construction machinery, industrial equipment assembly, and structural steel connections where high tensile strength and environmental resistance are mandatory requirements.
Specification Summary & Compliance
This metric hex head screw features precise Class 6g thread fit tolerances with M24 x 3mm coarse pitch threading and 140mm length. Manufactured to ISO 4014 specifications (equivalent to DIN 931) with Class 10.9 strength rating. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
