Key Features & Benefits at a Glance
- Superior corrosion resistance from 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Exceptional thread engagement and vibration resistance due to the fine UNF thread and precise Class 3A fit.
- High-strength performance with a Rockwell B80 hardness, ensuring the set screw maintains its form under load.
- Secure, flush mounting in confined spaces enabled by the headless design and compact 1/16" length.
- Reliable, high-torque installation using the 0.050" hex drive, preventing tool slippage and damage.
- Positive locking and minimal surface marring provided by the cup tip, which concentrates clamping force effectively.
- Guaranteed quality and material safety through compliance with ASME B18.3, RoHS 3, and REACH standards.
Professional Applications & Engineering Value
This 3-56 UNF set screw is engineered to solve critical challenges in precision assembly and machinery. The 18-8 Stainless Steel material offers excellent resistance to oxidation and chemical exposure, making it suitable for automotive, aerospace, and electronic enclosures where corrosion resistance is non-negotiable. Its headless and hex drive design allows for a flush finish in tight spaces, while the fine thread spacing and Class 3A thread fit ensure superior holding power against vibrations and dynamic loads. The cup tip provides a focused grip on shafts or components, reducing the risk of slippage. Ideal for securing collars, gears, and pulleys, this screw delivers reliable performance in high-stakes industrial applications.
Specification Summary & Compliance
This set screw adheres to Class 3A thread tolerance for a tight, precise fit. It conforms to the ASME B18.3 standard for dimensional accuracy and is manufactured with a UNF (Unified National Fine) thread form. The product is verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for hazardous substances.
