Professional Applications & Engineering Value
These low profile socket head cap screws deliver critical performance advantages in precision assembly applications where space constraints and reliability are paramount. The black-oxide alloy steel construction provides excellent corrosion resistance while maintaining 140,000 psi tensile strength, ensuring long-term fastener integrity in demanding environments. The 8-32 UNC coarse threads with Class 3A fit offer superior engagement and vibration resistance, while the low-profile head design enables installation in confined spaces common in machinery, automotive, and electronic enclosures. The partially threaded configuration allows for precise clamping force distribution, making these socket head cap screws ideal for applications requiring exact positioning and secure fastening.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit precision and UNC coarse thread specifications. These socket head cap screws comply with ASTM A574 manufacturing standards and meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements. The 1-1/2" length with 7/8" minimum thread length ensures consistent performance across industrial applications.
