S-8077A216 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure.
• Enhanced durability and wear resistance from the black oxide finish, which also reduces light reflection.
• High-strength performance with 70,000 psi tensile strength and 35,000 psi shear strength for reliable load-bearing in demanding applications.
• Precise assembly and secure fit thanks to the Class 3A thread fit and UNC coarse threading, ensuring minimal backlash and vibration resistance.
• Easy installation and removal with a hex socket drive (3/32") and knurled head for improved grip and torque application.
• Accurate component alignment provided by the 1" shoulder length with tight tolerances, maintaining part positioning in assemblies.
• Compliance with environmental standards, being RoHS 3 and REACH compliant for use in regulated industries.

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation, and industrial equipment. The UNC coarse thread and Class 3A fit ensure fast, secure fastening with high resistance to loosening under vibration, reducing maintenance needs. The black oxide finish enhances corrosion resistance, extending service life in humid or corrosive settings. With a 1" shoulder length and precise tolerances, it provides stable pivoting, alignment, and spacing in assemblies like bearings, linkages, and rotating parts, minimizing wear and improving operational reliability. Its high tensile and shear strength supports heavy-duty applications, from automotive to aerospace, where failure is not an option.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precision, and features a shoulder diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005" for consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufactured to high hardness (Rockwell B79) and strength specifications, it is suitable for rigorous industrial use without compromising on safety or durability.
