XunLiu Hex Socket Cup Point Set Screws M6X6mm - 50 Pack

XunLiu 316 Stainless Steel Set Screws – Industrial-Grade Fasteners Built for the Harshest Environments When standard 304 stainless screws start to rust in marine air, chemical splash zones, or continuously wet conditions, XunLiu 316 stainless steel set screws hold strong. The addition of molybdenum (Mo) in 316-grade steel dramatically enhances resistance to chloride-induced corrosion – the same reason it's the material of choice for boat fittings, offshore equipment, and food-processing machinery worldwide. This type of locking screw adopts a full-thread design and standard cup-shaped end (Cup Point), ensuring reliable clamping force when in contact with shaft-type parts, effectively preventing the parts from loosening or shifting during vibration or high-load operation. The hex socket (Hex Socket) driving method ensures that the operation is simple and the torque is accurately transmitted, whether for the assembly of precision instruments or engineering maintenance in narrow spaces. Whether you're building a 3D printer, repairing boat hardware, assembling CNC machine components, or replacing door handle set screws, XunLiu's full size range (M3 through M8, multiple lengths) gives you the right fastener for the job – at a price that makes stocking up easy.

• MARINE GRADE 316 STAINLESS STEEL – Superior Corrosion Resistance: Made from 316 stainless steel with molybdenum content, offering significantly better resistance to saltwater, acids, alkalis, and chloride environments than standard 304 SS. Perfect for boats, marine hardware, coastal equipment, chemical facilities, and any wet or harsh outdoor environment where rust-free performance is critical.
• INTERNAL HEX DRIVE – EASY, SLIP-FREE INSTALLATION: Standard hex socket (Allen key) drive ensures even torque distribution and prevents cam-out during installation. Compatible with standard hex keys and Allen wrenches. Great for tight spaces where traditional screwdrivers can't reach.
• MULTIPLE SIZES AVAILABLE – M3 to M8 IN VARIOUS LENGTHS: Available in a wide range of sizes (M3, M4, M5, M6, M8 with multiple lengths) to suit diverse applications including CNC machinery, RC models, door handles, faucets, furniture assembly, guitar tuning pegs, and general industrial maintenance.
• QUALITY GUARANTEED – CLEAN THREADS, ZERO BURRS: Every screw is carefully inspected for uniform thread pitch, sharp definition, and burr-free finish. XunLiu set screws meet industrial fastener standards to ensure reliable, long-lasting holding power with no stripping or loosening under vibration.
• M6X6MM CUP POINT SET SCREWS –50 PACK, DIN 916 STANDARD: Precisely manufactured to DIN 916 specifications with fully threaded design and cup (concave) point for superior grip and bite on mating surfaces. Ideal for securing shafts in motors, pulleys, collars, gears, 3D printers, and precision instruments where flush, headless fastening is required.
