Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
- Exceptional holding power provided by the cup point tip, which bites into surfaces to prevent loosening under vibration.
- Easy installation and removal with the external square drive and square head, allowing for high torque application without stripping.
- Durable and wear-resistant material with Rockwell B80 hardness, ensuring the screw maintains its integrity under repeated use.
- Reliable thread engagement due to the coarse UNC thread and Class 2A fit, enabling quick assembly and consistent performance.
- Broad industrial compatibility with compliance to ASME B18.6.2 standards, ensuring precise dimensions and interchangeability.
- Environmentally safe design meeting RoHS 3 and REACH regulations, reducing regulatory risks in global supply chains.
Professional Applications & Engineering Value
This 5/16"-18 UNC set screw is engineered to address common industrial challenges like component slippage and corrosion in demanding applications. The 18-8 Stainless Steel material offers excellent resistance to rust and chemicals, making it suitable for machinery, automotive assemblies, and outdoor equipment where moisture is a concern. The square head and external square drive facilitate secure tool engagement, reducing the risk of cam-out during high-torque installations. Paired with the cup point tip, it ensures a firm grip on shafts and collars, preventing rotational movement in dynamic systems. Its coarse thread design allows for faster assembly in soft materials or where vibration resistance is critical, enhancing productivity in manufacturing and maintenance operations.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 2A thread fit for consistent assembly and UNC coarse threads with a size of 5/16"-18. It meets ASME B18.6.2 specifications for mechanical and dimensional requirements, ensuring reliability in industrial fastening. Additionally, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in various global markets without hazardous substances.
