- Exceptional thread precision with Class 3A fit for secure, vibration-resistant assemblies and reduced risk of cross-threading
- High tensile strength of 70,000 psi provides reliable load-bearing capacity for demanding mechanical applications
- Rockwell B70 hardness offers excellent wear resistance and durability under repeated use
- Fine UNF thread design delivers superior holding power and improved adjustment precision in fine-pitch applications
- Standard hex socket drive (3/32") enables high-torque installation with common tools while minimizing head protrusion
- Full threading along the 1/2" length ensures maximum engagement and uniform stress distribution
Professional Applications & Engineering Value
These 4-48 UNF thread socket head cap screws provide critical solutions for precision assembly challenges where space constraints and vibration resistance are paramount. The combination of 18-8 stainless steel material and Class 3A thread fit addresses common industrial pain points including corrosion-induced failure, thread stripping, and loosening under dynamic loads. The fine thread configuration offers superior clamping force in thin materials and delicate components, while the socket head design allows for compact installations in confined spaces. Engineered to ASME B18.3 specifications, these fasteners deliver consistent performance in precision equipment, aerospace components, medical devices, and electronic enclosures where reliability cannot be compromised.
Specification Summary & Compliance
This socket head cap screw features precise Class 3A thread fit tolerances with 4-48 UNF fine threads in a right-hand direction. Manufactured to ASME B18.3 standards with full threading along the 1/2" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance compliance.
