Key Features & Benefits at a Glance
- Superior Tensile Strength – With 140,000 psi tensile strength, this screw ensures reliable, high-load fastening in demanding industrial environments.
- Enhanced Wear & Corrosion Resistance – The black-oxide finish on alloy steel provides excellent protection against rust and extends service life.
- Precise Thread Engagement – Class 3A fine UNF threads deliver tighter tolerances and superior vibration resistance compared to standard fits.
- Space-Saving Low Profile Design – The reduced head height allows installation in confined spaces without compromising on drive stability.
- Consistent High Hardness – Rockwell C39 hardness ensures the screw maintains its shape and thread integrity under repeated stress.
- Broad Regulatory Compliance – Meets ASTM A574 specifications and is RoHS 3 & REACH compliant, making it suitable for regulated and international projects.
- Fully Threaded Shank – Offers uniform clamping force along the entire length, ideal for applications requiring full thread engagement.
Professional Applications & Engineering Value
Engineered for precision and endurance, this low socket head cap screw addresses common challenges in machinery assembly, automotive systems, and heavy-duty equipment. The black-oxide alloy steel construction resists environmental degradation, while the fine UNF threads with Class 3A fit minimize loosening under vibration—critical for maintaining alignment in dynamic setups. Its 5/32" hex drive and low-profile head facilitate easy installation in tight spaces, reducing assembly time and improving access. These features make it a go-to industrial fastener for applications demanding high strength, durability, and consistent performance under stress.
Specification Summary & Compliance
This screw adheres to Class 3A thread fit for precise dimensional accuracy and is manufactured in accordance with ASTM A574. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety standards for global use.
