Flat Face Screw
Products Description
For critical fasteners in precision electrical equipment such as relays, our Flat Face Screws redefine industrial-grade screw standards with their low profile, high flatness, and strong adaptability. Designed for confined spaces and precision assembly scenarios, this product achieves a seamless fit with the mounting surface through optimized head structure and surface treatment, completely resolving issues such as component interference and aesthetic defects caused by protruding traditional screws. Whether fixing conductive plates in power cabinets or positioning relay coil frames, it provides a stable clamping force and a long lifespan, becoming an invisible guardian of reliable equipment operation. Among them, the flat-top design increases space utilization by 40%, providing core support for compact equipment layout and allowing precision manufacturing to return to its zero-redundancy essence.
Material Advantages
Stable Mechanical Properties
Flat Top Screws have a tensile strength of over 800MPa, possessing excellent tensile and shear resistance. They can withstand high-frequency vibrations and temperature changes during circuit breaker operation and are not prone to deformation or breakage.
Environmentally Friendly and Compliant Materials
All raw materials for Micro Flat Head Screws comply with RoHS and REACH standards, and are free of lead, cadmium, and other hazardous substances, meeting the industry trend of green environmental protection and adapting to the environmental requirements of new energy and high-end electrical equipment.
Wide Material Compatibility
Different materials can be flexibly matched to Flat Head Screws according to customers' usage scenarios and cost budgets. We offer cost-effective carbon steel products as well as high-performance copper alloy and stainless steel products to meet the needs of different levels of customers.
Manufacturing Process
Raw Material Selection and Pre-treatment
High-quality carbon steel wire is selected and pre-treated with pickling, degreasing, and wire drawing to remove surface impurities and oxide layers, laying the foundation for subsequent processing.
01
Core Forming Process
A combination of cold heading and precision turning is used. The wire head is first cold-headed to create a flat-face head structure, followed by thread machining and dimensional finishing on a CNC lathe to ensure the dimensional accuracy and flatness of the Low Profile Flat Head.
02
Thread and Surface Treatment Process
The Flat Head Machine Screw uses high-precision thread rolling technology to replace traditional turning, improving thread production efficiency and accuracy. Surface treatment is tailored to customer needs, employing electroplating, passivation, and other processes, with strict control over plating thickness and uniformity.
03
Quality Inspection and Control
Inspection points are set up at each process stage. Using equipment such as projectors, thread gauges, and salt spray test chambers, the dimensions, thread accuracy, and surface performance of the products are fully inspected to ensure that Thin Flat Head Screws meet quality system standards such as ISO9001-2015 and IATF16949.

Product Details
| Head Details | The Low Profile Flat Head is manufactured using a one-piece upset forming process, with a finely polished surface and a flatness error of ≤0.01mm. This ensures a seamless fit with the circuit breaker panel, preventing dust accumulation and poor contact. The head edges feature rounded corners to prevent scratching internal components during installation. |
| Thread Details | The Flat Head Machine Screw utilizes high-precision rolling technology, with a standard triangular tooth profile and a pitch tolerance of ≤0.005mm. The meshing clearance with the nut is controlled within 0.01mm, ensuring smooth installation and excellent tightening. The thread surface is free of burrs and broken teeth, guaranteeing long-term stability. |
| Screw Body Details | The screw body has a smooth surface, free of scratches and oxide layers. The length tolerance is controlled within ±0.02mm, adapting to mounting holes of different depths. The transition between the screw body and the head is stepless, reducing stress concentration during installation and extending the Thin Flat Head Screw's lifespan. |
| Surface treatment details | The zinc plating layer for Micro Flat Head Screw is ≥8μm thick and can withstand salt spray tests for more than 48 hours; the nickel plating layer has a bright and uniform surface, strong adhesion, and is not easy to peel off, making it suitable for humid and corrosive electrical working environments. |
