S-8077A179 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and chemical exposure.
• Enhanced durability and wear resistance from the black oxide finish, providing a protective layer against abrasion and reducing galling.
• High-strength performance offering 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable load-bearing in demanding applications.
• Precise thread engagement 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 hex drive (3/32"), combined with a knurled head for improved grip during manual handling.
• Accurate component alignment due to the consistent shoulder diameter (5/32") and length (1/4"), facilitating precise assembly in machinery and fixtures.
• Compliance with environmental and safety standards, including RoHS 3 and REACH, ensuring suitability for regulated industries and global supply chains.

Professional Applications & Engineering Value

These 6-32 UNC thread shoulder screws are engineered to address critical challenges in precision assemblies, such as maintaining alignment in rotating parts and reducing wear in high-stress joints. Made from 316 stainless steel, they resist corrosion from moisture, chemicals, and salt spray, making them ideal for marine, food processing, and pharmaceutical equipment. The black oxide finish not only enhances corrosion protection but also minimizes friction during installation. With a Class 3A thread fit and coarse thread spacing, these screws provide reliable fastening in applications subject to vibration, such as robotics, automotive fixtures, and electronic enclosures. The knurled head and hex drive design allow for quick, tool-free adjustments in tight spaces, improving assembly efficiency and reducing downtime in industrial settings.

Specification Summary & Compliance

This shoulder screw features a 6-32 UNC thread with Class 3A fit for precise tolerance, a shoulder diameter of 5/32" (tolerance: -0.004" to -0.002"), and shoulder length of 1/4" (tolerance: -0.005" to 0.005"). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
