Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and extended service life.
- Enhanced durability and wear resistance from the black oxide finish, providing added protection against abrasion and galling.
- High-strength performance with 70,000 psi tensile strength and 35,000 psi shear strength, ensuring reliable load-bearing in demanding applications.
- Precise alignment and smooth rotation due to the 1" diameter shoulder with tight tolerances, minimizing component wear.
- Secure, non-slip installation enabled by the knurled socket head and 1/2" hex drive, allowing for high-torque fastening.
- Accurate and reliable threading with Class 3A fit and coarse 3/4"-10 UNC thread, facilitating quick assembly and disassembly.
- Compliance with major industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety and regulatory acceptance.
Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in industrial applications where precision, strength, and corrosion resistance are paramount. The black oxide finish on the socket head not only enhances aesthetics but also reduces friction and prevents seizing in high-stress environments. The 1" shoulder diameter with controlled tolerances ensures exact component alignment, reducing wear on mating parts and maintaining operational integrity in machinery, pivoting mechanisms, and assembly jigs. Its coarse UNC thread and Class 3A thread fit provide a secure, vibration-resistant connection, making it ideal for heavy-duty fastener systems in manufacturing, automotive, and marine sectors where reliability under load is essential.
Specification Summary & Compliance
This shoulder screw features a 3/4"-10 UNC thread with a Class 3A thread fit for precise engagement, and a shoulder diameter tolerance of -0.004" to -0.002" for accurate alignment. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring it is free from hazardous substances and suitable for global industrial use.
