Precision Metric Standards
Shoulder-type screws, as a special type of fastener, have their core advantages in the precise positioning and anti-loosening effect brought by the shoulder design. They are widely used in equipment assembly, motion mechanisms, mold manufacturing, and other scenarios. YH FASTENER's Shoulder Screws Metric strictly follows international metric standards for production. The thread accuracy and shoulder position tolerance are controlled at the micrometer level, ensuring that each screw can achieve precise assembly and be suitable for various industrial scenarios with strict dimensional tolerance requirements. Whether it is the precise assembly of consumer electronics or the stable connection of automotive electronics, metric shoulder-type screws can meet the assembly needs of different industries with standardized specifications and reliable performance.
Diverse Head & Drive Designs
To adapt to different application scenarios and installation requirements, the shoulder screw series of YH FASTENER has diverse head and drive designs. Among them, the Socket Head Shoulder Screw adopts an internal hexagonal drive design, which can achieve countersunk installation. It not only saves equipment space but also can be uniformly tightened with a torque wrench, avoiding component damage caused by uneven force; while the Hex Head Shoulder Screw is compatible with traditional wrench tools and is convenient to install, suitable for large equipment and outdoor assembly scenarios, ensuring connection strength while significantly improving assembly efficiency. In addition, the Socket Shoulder Screw series products combine the advantages of shoulder positioning and internal drive tightening, and are commonly used connection components in scenarios such as molds and automated equipment.
Material Performance
In terms of material selection, YH FASTENER takes into account the usage environment and performance requirements of different industries when launching the Alloy Steel Shoulder Screw series. The alloy steel material undergoes a special heat treatment process, featuring high strength, high wear resistance, and anti-fatigue properties. It can withstand frequent disassembly and heavy-duty conditions. In fields such as automotive manufacturing and aerospace, which have extremely high requirements for component reliability, it demonstrates outstanding durability. At the same time, for some scenarios that require corrosion resistance, the company can also provide customized shoulder screws made of stainless steel, balancing strength and weather resistance.
Customized Solutions
In addition to the conventional internal hexagon and external hexagon shoulder screws, YH FASTENER can also provide customized products of special types according to customer needs, such as Headless Shoulder Screw and Shoulder Thumb Screw. The non-head shoulder screw is suitable for scenarios where the head of the fastener needs to be hidden to avoid component interference; the wing-shaped shoulder screw can be manually disassembled without tools and is suitable for equipment that requires frequent adjustment and disassembly, offering customers flexible and diverse assembly options.
