Product Overview
MALAXY, a leading fastener manufacturer headquartered in Shanghai, supplies premium machine screws — precision-engineered externally threaded fasteners designed for use with pre-tapped holes or nuts. Unlike bolts that rely on nut tightening, machine screws are driven by torque applied directly to the head, making them ideal for securing components in confined spaces and precision assemblies.
Machine screws feature a cylindrical shank with uniform external threads running the full length of the shank, a blunt (non-pointed) end, and a variety of head styles and drive types to suit diverse fastening requirements. These screws are manufactured in full compliance with international standards including DIN 84, ISO 1207, ISO 7045, ISO 7046, and ANSI/ASME B18.6.3, ensuring global compatibility and interchangeability.
Standards & Compliance
Standard | Description | Applicable Markets |
|---|
DIN 84 / ISO 1207 | Slotted cheese head machine screws, product grade A | Europe, Global |
ISO 7045 | Pan head screws with cross recess, product grade A | International |
ISO 7046 | Countersunk flat head screws with cross recess, product grade A | International |
ISO 7047 | Raised countersunk (oval) head screws with cross recess | International |
ANSI/ASME B18.6.3 | Machine screws — inch series, pan/flat/oval/truss heads | USA, North America |
DIN 963 | Slotted countersunk flat head machine screws | Europe |

All products undergo rigorous dimensional and mechanical testing to ensure compliance with the above standards. MALAXY maintains ISO 9001:2015 quality management certification throughout the manufacturing process.
Material Grades & Mechanical Properties
Material | Grade/Class | Tensile Strength | Corrosion Resistance | Typical Applications |
|---|
Low Carbon Steel | Class 4.8 | 400 MPa (min) | Low (requires coating) | General indoor assemblies |
Medium Carbon Steel | Class 8.8 | 800 MPa (min) | Low (requires coating) | Machinery, automotive components |
Alloy Steel | Class 10.9 | 1,040 MPa (min) | Low (requires coating) | High-strength mechanical joints |
Stainless Steel 304 (A2 / 18-8) | A2-70 | 500–700 MPa | Excellent | Food equipment, electronics, general-purpose |
Stainless Steel 316 (A4) | A4-70 | 500–700 MPa | Superior (saltwater/chemical) | Marine, offshore, medical, chemical processing |
Brass | — | 200–400 MPa | Good | Electrical applications, decorative assemblies |
Note: 18-8 stainless steel is equivalent to A2 (304) grade, widely specified in ASME/ANSI standards for machine screws.
Key Features
Fully Threaded Design – Uniform external threads along the entire shank length for maximum thread engagement and clamping force.
Blunt (Non-Pointed) End – Designed specifically for pre-tapped holes or use with nuts; not intended for self-tapping applications.
Multiple Head Styles – Available in pan head (rounded top, flat bearing surface), flat countersunk head (flush mounting), cheese head (cylindrical with slotted drive), oval raised head (decorative flush fit), and truss head (low-profile wide bearing surface).
Versatile Drive Options – Slotted (traditional flat-blade), Phillips cross recess (self-centering, high torque transmission), Phillips/Slotted combo, and Torx drives to suit manual or automated assembly requirements.
Multiple Material Options – Carbon steel, alloy steel, stainless steel 304/316, and specialty alloys for application-specific performance.
Surface Finishes – Plain (uncoated), zinc-plated (yellow/clear), black oxide (sleek appearance, minimal thickness addition), hot-dip galvanized (HDG), and custom coatings including Dacromet, Geomet, and Xylan.
SEMS (Pre-Assembled Washer) Option – Available with pre-assembled washers for reduced assembly time and improved cost efficiency in high-volume applications.
Applications
Machine screws are essential fasteners across virtually every industrial sector:
Industry | Specific Applications |
|---|
Electronics | Laptops, smartphones, cameras, televisions — fastening circuit boards, panels, casings, and components requiring secure yet serviceable connections |
Automotive | Dashboard panels, interior trim, door handles, headlights, license plates, engine accessories — Torx drive versions preferred for high-volume assembly lines |
Industrial Machinery | Control panels, conveyor systems, robotic arms, machine guards, precision instruments |
Appliances | Refrigerators, washing machines, dryers, ovens — securing internal components for durability and longevity |
Aerospace | Interior cabin components, avionics enclosures, lightweight assemblies requiring corrosion-resistant stainless steel |
Medical Equipment | Surgical instruments, diagnostic devices, hospital furniture — stainless steel 316 for biocompatibility and sterilization resistance |
Construction & Furniture | Handrails, lighting fixtures, switch covers, prefabricated assemblies — flat head countersunk screws for flush finish |
Surface Finishes
Finish | Corrosion Resistance | Appearance | Typical Applications |
