Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and extended service life.
- Excellent holding power provided by the cup point tip, which bites into the shaft for a secure, non-slip connection.
- Reliable thread engagement ensured by the Class 2A thread fit, offering consistent assembly and reduced risk of cross-threading.
- High mechanical strength with a Rockwell B80 hardness, providing durability and resistance to wear under load.
- Space-saving headless design allows for flush mounting in applications where protruding fastener heads are not feasible.
- Easy installation and adjustment with the simple slotted drive, compatible with standard screwdrivers for convenient maintenance.
- Broad industrial compatibility due to the standard 3/8"-16 UNC coarse thread, ensuring easy sourcing and replacement.
Professional Applications & Engineering Value
This 3/8"-16 UNC set screw is engineered to address common challenges in industrial fastening, such as component slippage and corrosion-induced failure. Manufactured from 316 Stainless Steel, it offers exceptional resistance to chemicals, moisture, and high temperatures, making it suitable for demanding sectors like marine, chemical processing, and food machinery. The headless slotted design with a cup point ensures maximum grip on shafts and collars, preventing rotational movement in assemblies. Its coarse thread and right-hand direction facilitate quick installation, while the robust material and Rockwell B80 hardness provide long-term reliability, reducing maintenance downtime and enhancing operational safety in B2B procurement scenarios.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 2A thread fit for consistent tolerance and the UNC thread type with a 3/8"-16 size. It is manufactured in compliance with ASME B18.3 specifications, ensuring interoperability and quality. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for various industrial applications.
