Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide finish extends service life in harsh industrial environments.
- Precise Class 3A thread fit guarantees secure, vibration-resistant connections for critical assemblies.
- High hardness (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use.
- Fully threaded design allows for maximum grip and adjustability across the entire 6" length.
- Coarse UNC thread enables quick installation and reduced cross-threading risks in demanding applications.
- 1/2" hex drive compatibility offers efficient torque application with standard tools, speeding up assembly processes.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these black-oxide alloy steel socket head cap screws address common challenges like vibration loosening and environmental degradation. The Class 3A thread fit ensures minimal play, critical for machinery subjected to dynamic loads, while the coarse UNC thread resists clogging in dirty or high-vibration settings. With a fully threaded rod type, they provide uniform clamping force across long spans, ideal for structural frames and equipment assembly. The black-oxide surface treatment not only enhances corrosion resistance but also reduces galling, making them suitable for automotive, construction, and manufacturing sectors where reliability and durability are paramount.
Specification Summary & Compliance
This socket head cap screw features a 5/8"-11 UNC coarse thread with Class 3A precision fit, ensuring tight tolerances per industry standards. Manufactured in compliance with ASTM A574 for consistent quality, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, supporting sustainable and safe usage in global markets.
