S-90337A451 10-32 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced Durability & Wear Resistance: TiCN coating provides superior surface hardness and extended service life in high-friction applications.
• Precision Alignment & Stability: Precise shoulder diameter tolerance (-0.001" to 0") ensures exact positioning and reduces component wobble.
• High Tensile Strength for Demanding Loads: 70,000 psi tensile strength and Rockwell B55 hardness offer reliable performance under mechanical stress.
• Space-Saving Low Profile Design: Low-profile socket head allows installation in confined spaces while maintaining secure hex drive engagement.
• Fine Thread Accuracy for Secure Fastening: 10-32 UNF fine threads with Class 2A fit deliver vibration-resistant, tight connections.
• Corrosion-Resistant Material Integrity: 18-8 stainless steel construction ensures excellent corrosion resistance in harsh industrial environments.
• Regulatory Compliance for Global Use: Meets RoHS 3 and REACH standards, ensuring environmental and safety compliance.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to address critical alignment and wear challenges in industrial machinery, automation systems, and precision instruments. The TiCN coated 18-8 stainless steel construction combats galling and abrasion in high-cycle applications, while the Class 2A thread fit and precise shoulder diameter tolerance (-0.001" to 0") eliminate play in rotating assemblies, pivots, and guide mechanisms. The low-profile socket head with 1/8" hex drive facilitates installation in tight spaces without compromising torque transmission. Ideal for CNC equipment, robotic arms, and optical mounts, it ensures long-term reliability and reduces maintenance downtime in demanding operational environments.

Specification Summary & Compliance

This shoulder screw adheres to UNF fine thread standards with Class 2A thread fit for consistent engagement. Shoulder diameter is manufactured to a tight tolerance of -0.001" to 0", and shoulder length is held to 0" to 0.002" tolerance for precise assembly. The screw conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of restricted hazardous substances. Manufactured from hardened 18-8 stainless steel with a tensile strength of 70,000 psi, it meets industrial requirements for strength and environmental compliance.
