Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments.
- Enhanced torque application and reduced slipping thanks to the knurled hex socket head design.
- High-strength performance with 70,000 psi tensile strength and 35,000 psi shear strength for demanding applications.
- Precise alignment and secure pivoting enabled by the consistent 1/4" shoulder diameter and 3/8" shoulder length.
- Reliable, coarse-thread engagement with the 10-24 UNC thread and Class 3A fit for vibration resistance.
- Compliance with major industry standards including ASME B18.3, ensuring interchangeability and quality.
- Environmentally responsible manufacturing with RoHS 3 and REACH compliance for global supply chain suitability.
Professional Applications & Engineering Value
This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and durability challenges in precision machinery, automation systems, and pivoting assemblies. The 10-24 UNC coarse thread and Class 3A thread fit provide excellent resistance to loosening under vibration, a common failure point in dynamic equipment. The 3/8" shoulder length acts as a precise datum for locating parts, reducing wear and misalignment. Manufactured from stainless steel with a Rockwell B55 hardness, it withstands corrosive environments and maintains integrity under repeated loads. The knurled socket head ensures secure drive engagement, preventing tool slippage during installation in confined spaces, making it a reliable choice for industrial fastening where precision and longevity are paramount.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC thread with a Class 3A fit for precise thread engagement. The shoulder diameter is 1/4" with a tolerance of -0.004" to -0.002", and the shoulder length is 3/8" with a tolerance of -0.005" to 0.005", ensuring consistent dimensional accuracy. It is manufactured in compliance with ASME B18.3 specifications and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, confirming adherence to strict environmental and safety standards.
