S-90357A011 10-32 x 3/4" Alloy Steel Ultra-Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Enhanced Corrosion Resistance with Black-Oxide coating on alloy steel, prolonging service life in demanding industrial environments.
• Precise Thread Engagement with Class 3A thread fit ensures reliable, vibration-resistant connections in critical assemblies.
• Superior Strength Under Load from 140,000 psi tensile strength and Rockwell C32 hardness, preventing stripping or failure.
• Space-Saving Ultra-Low Profile Head allows installation in confined areas without compromising drive stability.
• Fine UNF Threads (10-32) provide superior holding power and reduced risk of loosening in precision applications.
• Consistent Dimensional Accuracy with tight length tolerance (±0.005") for uniform performance across batches.
• Regulatory Compliance Assurance with RoHS 3 and REACH, meeting international environmental and safety standards.

Professional Applications & Engineering Value

Engineered for precision machinery, aerospace components, and automated systems, these ultra-low profile socket head cap screws address critical needs for reliable fastening in space-constrained designs. The Black-Oxide Alloy Steel construction combats corrosion in humid or chemically exposed settings, while the Class 3A UNF fine threads deliver exceptional clamp load retention under dynamic stresses. With a 140,000 psi tensile strength and Rockwell C32 hardness, they resist deformation in high-torque applications, ensuring long-term joint integrity. The 3/32" hex drive and fully threaded design facilitate quick installation and uniform stress distribution, making them ideal for CNC equipment, robotics, and precision instruments where failure is not an option.

Specification Summary & Compliance

This 10-32 UNF socket head cap screw adheres to inch system standards with a Class 3A thread fit for precise tolerance control. Dimensions include a 3/4" length (±0.005" tolerance), 5/16" head diameter, and ultra-low head profile. Manufactured from alloy steel with a Black-Oxide finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental safety and material traceability for global supply chains.
