Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh or chemical environments.
- Precise component alignment and pivot points enabled by the consistent 1/2" shoulder diameter and 3" shoulder length.
- High-strength performance with a tensile strength of 70,000 psi and a minimum shear strength of 35,000 psi for reliable load-bearing applications.
- Secure, high-precision threading with a Class 3A fit and 3/8"-24 UNF fine thread for vibration resistance and superior clamping force.
- Easy installation and removal using a standard 1/4" hex drive and a knurled socket head for improved grip.
- Guaranteed dimensional consistency and interchangeability, manufactured to meet the stringent ASME B18.3 specification.
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental standards.
Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw is engineered to solve critical challenges in precision assembly and motion control systems. The long, 3" shoulder length acts as a precise axle or pivot, eliminating the need for separate spacers and reducing assembly parts. The Class 3A UNF fine thread ensures a tight, secure fit that resists loosening under vibration, making it perfect for machinery, automotive, and aerospace applications. The combination of high tensile strength and excellent corrosion resistance provides long-term reliability in demanding environments, from food processing equipment to marine applications. Its knurled socket head and standard hex drive allow for efficient installation even in confined spaces, streamlining your production and maintenance processes.
Specification Summary & Compliance
This shoulder screw features a 3/8"-24 UNF fine thread with a high-precision Class 3A thread fit. The shoulder maintains a diameter of 1/2" with a tight tolerance of -0.004" to -0.002" and a length of 3" with a tolerance of -0.005" to 0.005". The product is manufactured in full compliance with the ASME B18.3 standard and adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
