Meet your diverse imperial fastening needs with our 304/Copper US Imperial UNF/UNC Hex Socket Convex End Stop Screws—available in both coarse and fine threads for precise fit in American-standard machinery, equipment, and industrial assemblies. Crafted from corrosion-resistant 304 stainless steel or conductive copper, these convex end stop screws deliver reliable positioning, locking, and load-bearing performance, making them ideal for automotive, aerospace, and precision tooling applications.
Core Features & Benefits
Dual Material Options for Versatile Use
Choose between 304 stainless steel for excellent rust, oxidation, and chemical resistance (perfect for humid, outdoor, or corrosive industrial environments) or high-purity copper for superior electrical conductivity and thermal transfer (ideal for electrical connections and grounding applications). Both materials ensure long-term structural stability and durability.
UNF/UNC Imperial Threads for Universal Compatibility
Available in UNC (coarse thread) for quick assembly and high load-bearing capacity, and UNF (fine thread) for precise adjustments, vibration resistance, and tight locking in high-precision machinery. Compliant with US imperial standards, these screws seamlessly fit American-made fixtures, engines, and mechanical components, eliminating cross-border compatibility issues.
Hex Socket & Convex End Design for Practical Performance
The hex socket drive enables stable tool engagement and precise torque control, even in narrow or recessed assembly spaces, preventing slippage and thread damage during installation. The convex end structure provides targeted stop and positioning functions, restricting component movement and ensuring dimensional accuracy in mechanical systems.
Stop Screw Function for Reliable Locking
Engineered as a dedicated stop screw, it effectively locks components in place, resists vibration-induced loosening, and maintains consistent assembly spacing. This design is critical for precision tooling, jig fixtures, and automotive engine parts that require fixed positioning under dynamic loads.
Wide Application in US-Standard Industrial Scenarios
Suitable for automotive chassis, aerospace components, precision instrument enclosures, electrical grounding systems, and industrial machinery fixtures. Whether for heavy-duty load-bearing or high-precision adjustment, these imperial screws meet the strict demands of diverse professional applications.
