Professional Applications & Engineering Value
This Grade 5 hex head screw delivers exceptional engineering value through its steel construction and black oxide surface treatment, specifically addressing industrial fastening challenges where corrosion resistance and structural reliability are paramount. The 1/2"-13 UNC coarse thread configuration prevents loosening in high-vibration environments common in machinery assembly, construction equipment, and structural frameworks. The partially threaded design concentrates clamping force precisely where needed, while the external hex drive accommodates high installation torque without stripping. Engineered to withstand extreme mechanical stress, these heavy-duty hex screws provide dependable performance in automotive, manufacturing, and infrastructure applications where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to exacting dimensional standards with Class 2A thread fit tolerances and UNC coarse thread spacing. Complies with ASME B18.2.1 specifications SAE J429, ensuring interchangeability and consistent performance. Meets RoHS 3 (2015/863/EU) compliance requirements for environmental safety. The 2" length with 1¼" minimum thread length provides precise engagement characteristics per industrial fastening standards.
