Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
- Maximum holding power achieved through Class 3A thread fit precision, ensuring secure fastening without loosening
- Easy installation and removal with hex drive design requiring only 0.035" hex key for convenient maintenance access
- Excellent grip and minimal surface damage from cup point tip design that bites securely into mating materials
- Reliable mechanical properties with Rockwell B80 hardness providing optimal strength without brittleness
- Industry-standard compatibility through UNC coarse thread pattern (2-56) for broad application across equipment and machinery
- Space-saving headless design allowing flush mounting where clearance is limited
Professional Applications & Engineering Value
These 2-56 UNC set screws deliver critical engineering solutions for precision assembly challenges. The 18-8 stainless steel composition provides exceptional corrosion resistance in demanding environments like marine equipment, food processing machinery, and outdoor applications. The hex drive configuration enables high-torque installation while the cup point tip creates permanent seating that prevents rotational slippage in shafts, collars, and pulleys. With Class 3A thread fit and coarse thread spacing, these headless set screws maintain positional accuracy in vibrating systems while offering quick assembly in production lines. The combination of Rockwell B80 hardness and precise manufacturing ensures consistent performance in high-stress mechanical applications where reliability is paramount.
Specification Summary & Compliance
This 2-56 UNC set screw features precise Class 3A thread fit tolerances with 0.086" thread diameter and 1/8" length. Manufactured to ASME B18.3 specifications with right-hand thread direction and coarse thread spacing. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
