Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 stainless steel construction and black oxide finish, ideal for harsh industrial environments.
- Precise alignment and smooth rotation due to the 2" shoulder with tight ±0.005" length tolerance, reducing wear on mating parts.
- High mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable performance in demanding applications.
- Easy installation and removal with the hex socket drive and knurled head, providing superior grip and torque transmission.
- Consistent thread engagement ensured by the 10-24 UNC coarse thread with Class 2A fit, minimizing cross-threading risks.
- Durable and hardened to Rockwell B55, maintaining structural integrity under repeated stress and vibration.
- Compliant with environmental regulations, meeting RoHS 3 and REACH standards for safe and sustainable use.
Professional Applications & Engineering Value
This 10-24 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision machinery, such as rotating assemblies, pivots, and guides. The 18-8 stainless steel material combined with a black oxide finish provides excellent resistance to corrosion and oxidation, extending service life in humid or chemically aggressive settings. The 2" shoulder length with minimal tolerance ensures exact positioning, reducing backlash and component wear. Its coarse thread and Class 2A fit facilitate quick assembly while maintaining secure fastening, making it ideal for industrial equipment where reliability and ease of maintenance are paramount.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder diameter and length tolerances are tightly controlled (e.g., shoulder length: -0.005" to 0.005"). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory adherence for global industrial use.
