S-92183A523 1"-8 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
• Precise thread engagement and reliable fastening due to Class 3A thread fit, minimizing the risk of loosening under vibration.
• High tensile and shear strength (70,000 psi tensile, 35,000 psi min shear) for demanding applications requiring robust load-bearing capabilities.
• Easy installation and removal with a 1/2" hex drive and knurled head for superior grip, even with gloved hands.
• Versatile shoulder design providing a precise bearing surface and accurate component location in assemblies.
• Compliance with major environmental regulations (RoHS 3 & REACH), ensuring suitability for global supply chains.
• Durable and long-lasting performance backed by a Rockwell B55 hardness rating, resisting wear and deformation.

Professional Applications & Engineering Value

This 1"-8 UNC Thread Shoulder Screw is engineered to solve critical alignment and pivot point challenges in industrial machinery, automation systems, and precision equipment. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for wash-down environments or outdoor applications. The coarse UNC thread and Class 3A fit ensure a secure, tight connection that resists vibrational loosening, a common failure point in dynamic assemblies. The integral 1" shoulder diameter acts as a precise shaft or pivot, maintaining accurate alignment of components like gears, pulleys, and linkages. The combination of a 1/2" hex drive and a knurled head facilitates quick and secure installation, reducing assembly time and improving worker safety. This fastener delivers reliable engineering value by enhancing the durability, precision, and maintenance efficiency of your mechanical designs.
