Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 PSI ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the zinc-flake coating protects against harsh industrial environments, extending the screw's service life.
- High-precision Class 3A thread fit provides secure, vibration-resistant fastening with minimal risk of loosening.
- Partially threaded design allows for precise clamping force control, ideal for applications requiring specific grip lengths.
- Hex socket drive (5/32") enables high-torque installation with standard tools, preventing cam-out and ensuring efficient assembly.
- Compliance with ASME B18.3 and ASTM A574 guarantees consistent quality and dimensional accuracy for reliable interchangeability.
- Rockwell C37 hardness offers excellent wear resistance, maintaining thread integrity through repeated use.
Professional Applications & Engineering Value
These 10-24 UNC Socket Head Cap Screws are engineered to solve critical fastening challenges in demanding environments. The zinc-flake-coated alloy steel construction provides outstanding protection against corrosion, making them ideal for machinery, automotive assemblies, and outdoor equipment exposed to moisture or chemicals. The coarse UNC thread and Class 3A fit ensure quick installation and superior vibration resistance, reducing maintenance needs in dynamic applications. With a partially threaded shank, they offer precise clamping where full threading isn't required, preventing joint distortion. Their high tensile strength and hex drive design support heavy-duty use in construction, aerospace, and manufacturing, delivering long-term reliability and reduced downtime.
Specification Summary & Compliance
This socket head cap screw features a 10-24 UNC coarse thread with a Class 3A thread fit for precise tolerances, and a length of 1 3/4" with a minimum thread length of 7/8". It complies with ASME B18.3 and ASTM A574 specifications for dimensional and material consistency. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental and safety regulations for industrial use.
