S-8077A686 6-32 Shoulder Screws

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 a protective layer against abrasion and galling.
• High-strength performance offering 70,000 psi tensile strength and 35,000 psi shear strength for reliable load-bearing in demanding applications.
• Precise and secure fastening with Class 3A thread fit, ensuring tight tolerances and reduced risk of loosening under vibration.
• Easy installation and removal using a standard 3/32" hex drive and knurled head for improved grip and torque application.
• Optimized for coarse threading applications with UNC threads, facilitating quicker assembly and better performance in softer materials.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in regulated industries.

Professional Applications & Engineering Value

This 316 Stainless Steel shoulder screw is engineered to address critical challenges in precision assembly and machinery. The UNC coarse threading and Class 3A fit provide exceptional dimensional accuracy, minimizing play and ensuring consistent alignment in pivots, linkages, and rotating components. The Black Oxide finish not only enhances corrosion resistance but also reduces friction, preventing seizing in high-cycle operations. With a Rockwell B79 hardness and high tensile strength, it withstands repetitive stress and shear forces in automotive, aerospace, and industrial equipment, offering reliable performance where failure is not an option. The integrated shoulder acts as a precise spacer or bearing surface, simplifying design and reducing the need for additional parts.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A fit for precise thread engagement. Key dimensional tolerances include a shoulder diameter of 3/16" (tolerance: -0.004" to -0.002") and shoulder length of 1/8" (tolerance: -0.005" to 0.005"). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
