S-91273A537 10-24 Shoulder Screws

Key Features & Benefits at a Glance

• Corrosion-resistant performance with 18-8 stainless steel and black oxide finish, ideal for harsh industrial environments.
• High tensile and shear strength (70,000 psi tensile, 35,000 psi shear) ensures reliable load-bearing in demanding applications.
• Precise thread engagement with Class 2A UNC coarse threads for quick assembly and vibration resistance.
• Secure hex drive operation using a 3/32" hex key, combined with a knurled head for enhanced grip during installation.
• Accurate shoulder alignment with controlled diameter and length tolerances for consistent component positioning.
• Durable material hardness (Rockwell B55) maintains thread integrity and resists wear under repeated use.
• Environmental compliance with RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address critical alignment and fastening challenges in machinery, automation, and precision assemblies. The 18-8 stainless steel construction, enhanced by a black oxide finish, provides excellent corrosion resistance, reducing maintenance in humid or chemically exposed settings. The coarse UNC threads and Class 2A fit enable rapid installation while minimizing cross-threading risks. The knurled socket head and hex drive design offer superior torque transmission, preventing slippage during high-stress tightening. With a robust shoulder diameter of 3/16" and controlled tolerances, it ensures precise pivot points and bearing surfaces in rotating mechanisms, making it ideal for use in industrial equipment, motor mounts, and conveyor systems where reliability and repeatability are paramount.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. Key dimensional attributes include a shoulder diameter of 3/16" (tolerance: -0.004" to -0.002") and shoulder length of 3/8" (tolerance: -0.005" to 0.005"). The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of restricted hazardous substances. Manufactured to deliver 70,000 psi tensile strength and 35,000 psi shear strength, it is suitable for applications requiring high mechanical performance and regulatory conformity.
