Full Grade Product Features & Advantages
Full Gradient Strength for Diversified Working Conditions
Our DIN913 set screws cover three mainstream industrial strength grades: 8.8, 10.9 and 12.9, with graded performance suitable for light, medium and heavy-duty positioning scenarios. Grade 8.8 offers high cost performance for static fastening; Grade 10.9 delivers balanced performance for slightly vibrating equipment; Grade 12.9 features ultra-high strength to withstand heavy load and high-frequency impact without loosening or fracture, realizing one-stop model selection.
Flat Non-marking Design for Precision Positioning
The standard flat end provides uniform contact force, avoiding scratching or damaging precision workpieces such as shafts and mold inserts. Equipped with 6H precision threads, the screws are tightly locked, not easy to slip after repeated disassembly and assembly, and maintain long-term positioning accuracy, perfectly suitable for high-precision equipment assembly.
Multiple Anti-corrosion Finishes for Harsh Environments
Various customized surface treatments are available for all strength grades. Black oxide finish is economical for indoor dry environments. Zinc plating, Dacromet and Geomet finishes are applicable for outdoor, humid and corrosive environments, effectively improving rust and corrosion resistance and extending service life.
Grade 8.8 DIN913 Set Screws
Made of high-quality carbon steel with quenching and tempering treatment, featuring moderate hardness, good toughness and high cost performance. Widely used for static light-duty positioning of electromechanical equipment, tooling fixtures and sheet metal structures without severe vibration.
Grade 10.9 DIN913 Set Screws
Manufactured from 40Cr alloy steel with enhanced heat treatment, featuring higher strength and fatigue resistance than Grade 8.8. Ideal for automated assembly lines, hydraulic equipment, medium and small molds, motor gear shafts and other medium-load working conditions with slight vibration.
Grade 12.9 DIN913 Set Screws
Adopting 42CrMo high-strength alloy steel with high-temperature quenching and tempering, Grade 12.9 is the top industrial strength grade with high hardness, wear resistance and impact resistance. Specially designed for high-load, high-precision core positioning scenarios such as precision die-casting molds, high-speed spindles, CNC tooling and high-end automation equipment.
Production Process
Graded Material Selection: Match carbon steel, 40Cr and 42CrMo raw materials according to different strength grades to ensure stable mechanical performance.
Precision Cold Heading Forming: One-piece cold heading molding with regular hexagonal grooves and smooth flat ends without burrs.
Precision Thread Rolling: High-precision thread rolling ensures full thread profile and standard tolerance with strong interchangeability.
Graded Heat Treatment: Customized temperature-controlled quenching and tempering for each strength grade to meet standard hardness and tensile properties.
Custom Surface Treatment: Provide professional rust and corrosion protection according to customer working conditions.
Full Batch Inspection: Test dimensions, hardness, thread accuracy and tensile properties batch by batch, providing authoritative quality inspection reports.
Application Industries
Mold Manufacturing: Positioning and limiting of plastic molds, hardware molds and die-casting mold inserts (Grade 12.9 preferred).
Automation Equipment: Locking and positioning of assembly line tooling, manipulator fixtures and precision jigs (Grade 10.9/12.9).
Motor Transmission Equipment: Anti-loosening limiting of motor output shafts, gear shafts and transmission shafts.
Precision Instrument Equipment: Limiting and fixing of testing instruments and optical equipment parts (Grade 8.8/10.9).
General Machinery Industry: Internal structural positioning and fastening of reducers, machine tools and electromechanical equipment.
