• High Tensile Strength: Withstands up to 140,000 psi tensile strength, offering exceptional load-bearing capacity for critical assemblies.
• Secure Drive Engagement: Hex socket drive with 1/8" size and low-profile knurled head allows for easy installation and prevents tool slippage under torque.
• Accurate Shoulder Positioning: Precision-machined shoulder with tight diameter and length tolerances ensures consistent part spacing and rotational stability.
• Broad Compatibility: UNC coarse threads and right-hand direction enable quick assembly and interchangeability with standard inch-system components.
• Regulatory Compliance: Meets RoHS 3 and REACH environmental standards, ensuring safe use in regulated industries worldwide.

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address common challenges in precision machinery, automation systems, and tooling fixtures. The alloy steel core, hardened to Rockwell C30, resists wear and deformation under repetitive stress, while the black oxide finish adds a protective layer against rust and abrasion. The Class 3A thread fit and controlled shoulder dimensions minimize assembly play, critical for maintaining alignment in rotating components like bearings, pulleys, and linkages. Its low-profile socket head with knurling offers secure tool engagement in confined spaces, reducing installation time and improving worker safety. Ideal for OEMs and maintenance teams, this screw ensures reliable performance in applications demanding high strength, dimensional accuracy, and regulatory adherence.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A fit for precise engagement. Key dimensions include a 10-24 thread size, 3/8" shoulder length, and 1/4" shoulder diameter, manufactured to tight tolerances (e.g., shoulder diameter: -0.004" to -0.002"). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The product meets industry benchmarks for hardness (Rockwell C30) and tensile strength (140,000 psi), supporting consistent performance in regulated and high-stress applications.
