Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
- Exceptional thread engagement and vibration resistance due to Class 3A thread fit, ensuring secure fastening in high-stress applications.
- High mechanical strength and durability provided by Rockwell B80 hardness, reducing wear and deformation under load.
- Easy installation and removal with a 5/32" hex drive, allowing for efficient assembly and maintenance with standard tools.
- Firm gripping and positioning from the 90° cone point, which digs into surfaces to prevent component slippage.
- Reliable performance in coarse threading with UNC thread type, facilitating quick assembly and strong holding power.
- Compact and space-saving design as a headless set screw, perfect for applications where protrusion is a concern.
Professional Applications & Engineering Value
This 5/16"-18 UNC set screw is engineered to address common industrial challenges such as component misalignment and loosening under dynamic loads. Crafted from 18-8 Stainless Steel, it offers excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive, and outdoor equipment. The hex drive and headless design allow for flush mounting in tight spaces, while the 90° cone point ensures deep penetration into shafts or hubs, providing reliable torque transmission and rotational security. Its coarse thread and Class 3A thread fit enhance grip strength, reducing the need for frequent retightening in heavy-duty applications. Compliant with ASME B18.3, this screw delivers consistent performance in precision assemblies, from conveyor systems to motor mounts.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 3A thread fit for tight tolerances and UNC coarse threading with a 5/16"-18 size. It conforms to ASME B18.3 specifications for reliability and interoperability. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and regulatory adherence for global industrial use.
