XunLiu Grade 10.9 Alloy Steel Button Head Hex Socket Screws (M3X45)

XunLiu Grade 10.9 Alloy Steel Button Head Hex Socket Screws (M3X45)

GRADE 10.9 ALLOY STEEL WITH SUPERIOR STRENGTH - Heat-treated high-tensile alloy steel delivers exceptional 150,000 PSI minimum tensile strength with outstanding shear and fatigue resistance; engineered for high-stress applications including machinery assembly, automotive components, and industrial fixtures requiring maximum durability ZINC-PLATED CORROSION PROTECTION - Professional-grade zinc plating provides reliable protection against rust and oxidation in various environments; extends fastener lifespan and maintains appearance across industrial, automotive, and demanding outdoor applications without coating failures LOW-PROFILE BUTTON HEAD DESIGN - Precision-engineered rounded head minimizes protrusion, reduces clearance issues, and delivers sleek finished appearance ideal for precision assemblies where aesthetic quality and compact fitting are critical requirements INTERNAL HEX SOCKET DRIVE - Allen hex socket drive enables high-torque tightening with reduced cam-out risk compared to Phillips heads; compatible with standard hex wrenches and power driver bits for efficient installation across variable applications and project scales VERSATILE SIZING & BULK AVAILABILITY -M3X45(50pcs)metric specifications with available quantities (10/50/100 packs) accommodate small precision projects through large-scale industrial assembly; metric threading ensures compatibility with European and international standards and specifications Engineered for demanding applications requiring exceptional strength and reliability. Made from alloy steel heat-treated to achieve Grade 10.9 tensile strength (150,000 psi minimum), offering superior shear and tensile load resistance. The low-profile, rounded button head provides a finished appearance while minimizing clearance issues. The internal hex socket drive (Allen drive) allows high torque application with reduced cam-out risk compared to Phillips heads. Ideal for machinery, automotive components, jigs, fixtures, and structural assemblies where high fatigue resistance and hardness are critical. Zinc plating typically supplied for basic corrosion protection.
