Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life.
- Exceptional holding power provided by the Class 3A thread fit, ensuring a precise, secure, and vibration-resistant connection.
- High-torque application capability from the 9/16" hex drive, allowing for easy installation and removal with standard tools.
- Optimized for high-vibration settings with coarse UNC threads and a cup tip design that bites into the material for a non-slip grip.
- Long-term mechanical reliability guaranteed by a Rockwell B80 hardness, resisting wear and deformation under load.
- Streamlined, headless design for use in confined spaces where a protruding head is not permissible.
- Guaranteed quality and safety through compliance with ASME B18.3, RoHS 3, and REACH regulations.
Professional Applications & Engineering Value
This 18-8 Stainless Steel Set Screw is engineered to solve critical challenges in industrial assembly and machinery. Its headless design and right-hand UNC coarse threads make it perfect for securing collars, gears, and pulleys onto shafts in high-vibration environments where components must remain locked in position. The cup tip concentrates force for a superior grip, preventing slippage that can lead to equipment failure. The Class 3A thread fit provides a tighter tolerance than standard fits, essential for precision applications in automotive, aerospace, and heavy machinery. Manufactured from corrosion-resistant 18-8 stainless steel, it delivers long-term performance even when exposed to moisture, chemicals, or outdoor conditions, reducing maintenance frequency and total cost of ownership.
Specification Summary & Compliance
This set screw features a 1"-8 UNC coarse thread with a precision Class 3A thread fit and a length of 2". It is manufactured in accordance with the ASME B18.3 specification. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent international standards for hazardous substance restrictions.
