Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
- High-strength performance with 70,000 psi tensile strength and 35,000 psi shear strength, ensuring reliable load-bearing in demanding applications.
- Precise Class 3A thread fit for secure, vibration-resistant assemblies and consistent mating with threaded components.
- Enhanced grip and tool engagement from the knurled head and 5/64" hex drive, preventing slippage during installation.
- Versatile shoulder lengths (2"-3.99") provide accurate spacing and act as a pivot or axle in mechanical assemblies.
- Durable Rockwell B55 hardness maintains thread integrity and resists wear under repeated use.
- Compliant with RoHS 3 and REACH regulations, meeting international safety and environmental standards for global supply chains.
Professional Applications & Engineering Value
This 1-64 UNC shoulder screw is engineered to address critical alignment and rotational challenges in precision assemblies. The 18-8 stainless steel material offers excellent resistance to oxidation and chemicals, reducing maintenance in machinery, electronics, and automotive systems. The coarse thread spacing and Class 3A fit ensure quick, secure fastening with minimal risk of cross-threading, while the knurled head enhances manual handling in tight spaces. With a right-hand thread and hex drive, it simplifies installation in jigs, pivots, and bearing mounts, providing consistent performance where dimensional accuracy is paramount. The shoulder diameter and length tolerances guarantee precise positioning, making it a reliable choice for OEMs and MRO applications requiring durability and compliance.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Dimensions include a head diameter of 5/32", shoulder diameter of 3/32" with tight tolerances, and thread length of 1/8". It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufactured to deliver 70,000 psi tensile strength and 35,000 psi minimum shear strength, it is suitable for rigorous industrial use.
