Professional Applications & Engineering Value
Engineered for demanding industrial applications, these socket head cap screws combine the corrosion-resistant properties of 18-8 stainless steel with the precision of UNF fine threads to solve critical fastening challenges. The Class 3A thread fit provides superior vibration resistance in machinery, automotive, and aerospace assemblies where loosening under dynamic loads is a concern. The partially threaded design concentrates strength where needed most, while the hex socket drive allows for high-torque installation in space-constrained applications. With 70,000 psi tensile strength and Rockwell B70 hardness, these screws maintain integrity in high-stress environments, making them ideal for precision equipment, manufacturing fixtures, and structural applications requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
This 1/4"-28 UNF socket head cap screw features Class 3A thread fit for precision tolerance, fine thread spacing, and partial threading with minimum 1" thread length. Manufactured to ASME B18.3 specifications for dimensional consistency and performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors.
