- Class 2A thread fit with 10-32 UNF fine threading offers precise, secure fastening in tapped holes with reduced risk of cross-threading.
- 1/8" hex drive and rounded button head allows for easy installation in confined spaces with standard tools.
- Full threading along the 1/2" length ensures maximum grip and adjustability in various material thicknesses.
Professional Applications & Engineering Value
This 6061 aluminum flanged rounded head screw is engineered to address common challenges in precision machinery, electronics, and lightweight structural assemblies. The 10-32 UNF fine thread and Class 2A fit provide exceptional holding power in thin materials, reducing the risk of stripping. The integrated flange acts as a built-in washer, distributing clamping force to prevent surface damage and maintain joint integrity under vibration. With a Rockwell B40 hardness and 40,000 psi tensile strength, it withstands dynamic loads while the hex drive ensures secure torque application. Ideal for applications requiring RoHS and REACH compliance, it offers a reliable, corrosion-resistant fastening solution for OEM and MRO needs.
Specification Summary & Compliance
This screw features a 10-32 UNF fine thread with Class 2A thread fit per standard inch specifications, ensuring dimensional accuracy and interchangeability.
