Key Features & Benefits at a Glance

  • Exceptional strength-to-weight ratio from Grade 5 Titanium construction, providing high load capacity without adding unnecessary bulk.
  • Superior corrosion resistance for long-lasting performance in harsh industrial environments, reducing maintenance and replacement costs.
  • High tensile strength of 130,000 psi ensures reliable fastening under extreme stress and vibration.
  • Rockwell C36 hardness provides excellent wear resistance and durability for repeated use.
  • Coarse UNC threads with Class 2A fit allow for quicker installation and easier alignment in a variety of materials.
  • Partially threaded design offers optimal grip and clamping force where a fully threaded fastener isn't required.
  • Compliance with RoHS 3 and REACH regulations guarantees environmental safety and unrestricted use in regulated industries.

Professional Applications & Engineering Value

This Grade 5 Titanium hex head screw is engineered to solve critical challenges in demanding sectors like aerospace, chemical processing, and marine equipment. The 1/2"-13 UNC coarse thread and external hex drive facilitate rapid assembly and disassembly, even in confined spaces. Its partially threaded shank concentrates clamping force precisely, preventing joint loosening under dynamic loads. The inherent corrosion resistance of titanium eliminates galvanic and atmospheric degradation, making it ideal for applications where stainless steel may fail. Combined with a high tensile strength and Rockwell C36 hardness, this fastener delivers long-term reliability, reducing downtime and total cost of ownership in critical industrial fastening systems.

Specification Summary & Compliance

This screw features a 1/2"-13 UNC thread with a Class 2A thread fit for standard tolerance and interchangeability. It is manufactured from Grade 5 Titanium to deliver a tensile strength of 130,000 psi and a hardness of Rockwell C36. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for industrial use.
