Professional Applications & Engineering Value
This flanged socket head cap screw delivers critical engineering advantages where vibration resistance and corrosion protection are paramount. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, making it ideal for industrial machinery, automotive assemblies, and marine equipment. The 1/4"-20 UNC coarse threads with Class 3A fit ensure rapid installation while maintaining precise alignment in high-vibration applications. The integrated flange distributes clamping force evenly, preventing surface damage while the partially threaded design provides optimal grip length control. These features combine to create a high-strength fastener that reduces maintenance frequency and improves equipment reliability in demanding environments.
Specification Summary & Compliance
Manufactured to inch system standards with Class 3A thread fit precision and UNC coarse thread profile. Features include: 1/4"-20 thread size, 1-7/16" overall length, 1" grip length, and 3/16" hex drive. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 80,000 PSI tensile strength and Rockwell B83 hardness ensure consistent performance across industrial applications requiring reliable fastening solutions.
