- Optimized for controlled engagement through a partially threaded design, preventing over-tightening and material damage.
- Broad industrial compliance meeting ASME B18.6.3 standards, ensuring dimensional accuracy and interchangeability.
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives.
- Simple and reliable installation using a standard slotted drive, compatible with common hand and power tools.
Professional Applications & Engineering Value
This 10-32 UNF rounded head slotted screw is engineered to solve critical fastening challenges in industrial settings. The 18-8 stainless steel material, enhanced by a passivated finish, provides excellent resistance to oxidation and chemical exposure, making it ideal for machinery, marine equipment, and food processing applications where moisture is a concern. The partially threaded shank design allows for precise clamp load control, preventing joint failure in assemblies with varying material thicknesses. Its fine thread spacing and Class 2A fit ensure a tight, secure connection that resists vibration-induced loosening, a common failure point in dynamic systems. By conforming to ASME B18.6.3, this screw guarantees dimensional consistency and reliability in high-volume production and maintenance operations.
Specification Summary & Compliance
This screw features a 10-32 UNF thread with a Class 2A tolerance for precise fit, a length of 2 1/2", and a minimum thread length of 1 1/2". It is manufactured in accordance with the ASME B18.6.3 standard and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
