- Exceptional hardness (Rockwell C37) provides excellent wear resistance and durability, extending the service life of your assemblies.
- Precise Class 3A thread fit guarantees secure, vibration-resistant connections, minimizing loosening in demanding environments.
- Black-oxide finish on alloy steel offers enhanced corrosion resistance for improved longevity in various operating conditions.
- Standard hex socket drive allows for high-torque installation with common tools, facilitating efficient assembly and maintenance.
- Partially threaded design provides an unthreaded shoulder for precise clamping and alignment in machined components.
- Compliance with ASTM A574 ensures consistent quality and material integrity for critical fastening applications.
Professional Applications & Engineering Value
These 10-24 socket head cap screws are engineered to address common challenges in machinery, automotive, and heavy equipment assembly. The black-oxide alloy steel construction combats corrosion while the UNRC coarse thread and Class 3A fit provide superior grip and vibration resistance in high-vibration environments. The partially threaded rod allows the unthreaded portion to act as a precision dowel, preventing shear forces and ensuring accurate component alignment. With a 5/32" hex drive, they enable high clamping force application in confined spaces, making them ideal for industrial fasteners in demanding applications where reliability and strength are non-negotiable.
Specification Summary & Compliance
This product adheres to Class 3A thread fit for precision and meets ASTM A574 specifications for alloy steel socket head cap screws. It is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental and safety standards are met for global industrial use.
