Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Superior holding power from the cup point design that bites deeply into materials, preventing component slippage.
- High-strength performance backed by Rockwell B80 hardness, ensuring durability under load and repeated use.
- Precise and secure fastening with a Class 3A thread fit, providing tighter tolerances for vibration-resistant assemblies.
- Easy installation in confined spaces using the 0.050" hex drive and headless design, allowing flush mounting.
- Reliable coarse (UNC) threading for quicker assembly and reduced cross-threading risk in industrial applications.
- Compliance with major industry standards including ASME B18.3, ensuring consistent quality and interchangeability.
Professional Applications & Engineering Value
Engineered for demanding industrial set screw applications, this 3-48 UNC set screw in 18-8 stainless steel provides a robust solution for securing components on shafts, collars, and pulleys. The headless design and hex drive (0.050") enable installation in tight spaces where protruding fasteners are not feasible. Its cup point concentrates force to create a permanent, non-slip grip, effectively resisting loosening from vibrations—a common challenge in machinery and automation equipment. Combined with a Class 3A thread fit and coarse thread spacing, it ensures quick, accurate assembly while maintaining alignment. This fastener is ideal for precision engineering, automotive, and electronics sectors, where material integrity and regulatory adherence are critical.
Specification Summary & Compliance
This set screw meets precise dimensional standards, including a Class 3A thread fit for superior tolerance and a UNC thread type with coarse spacing. Manufacturing and quality are governed by ASME B18.3 specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in various markets.
