Cross Recessed Screw
Products Description
Cross Recessed Screws, also known as Phillips screws, are the most common and widely used type of fastener. Their cross-shaped recess in the screw head facilitates installation using a Phillips screwdriver or automated tools, ensuring both efficiency and operational stability. As a standardized industrial component, Stainless Steel Nut for Screw Bolt plays an irreplaceable role in machinery manufacturing, electronic equipment, the automotive industry, new energy devices, and construction.
In the global fastener market, steel screws have become a key focus for buyers and engineering designers due to their simple design, excellent torque transmission capacity, and diverse material options.
Manufacturing Advantages
One-step cold heading
Wire is formed at room temperature using multiple high-speed stamping stations. This results in a continuous distribution of metal fibers, significantly enhancing head strength and shear resistance, and avoiding the loosening of the thread caused by cutting.
Precision thread rolling
The threads utilize a double-roll rolling process to form a cold-work hardened layer, resulting in a smooth, burr-free surface, uniform thread pitch, and high-precision fit, which effectively reduces threading resistance and improves locking force.
Fully automated production line integration
Equipped with imported cold heading machines, automatic thread rolling machines, screening machines, and a visual inspection system, this enables unmanned operations from raw material intake to finished Grub Screw packaging, reducing human error and ensuring high consistency even for orders exceeding one million.
A rigorous process inspection mechanism
Each batch undergoes torque testing, salt spray testing, head pressure testing, and visual inspection to ensure that all Stainless Steel Screws are free of cracks, eccentricity, and excess lubrication residue.
Details
Surface Finish
The coating is uniform and burr-free, ensuring an aesthetically pleasing appearance and enhanced protective performance.
Thread Accuracy
The threads are clean and flawless, ensuring smooth lagging without any sticking or slipping.
Head Groove
The groove is uniformly deep and precisely angled, ensuring a perfect fit between the tool and the set screw.
Design Advantages
| Adaptable Head Shape Design | Optimized head structure for different installation requirements. Stainless Steel Screws feature a 120° taper angle, allowing them to sit flush with the workpiece surface, making them suitable for applications requiring high aesthetics, such as architectural decoration and furniture assembly. Round head screws feature an optimized head curvature to enhance their pressure-bearing capacity, making them suitable for equipment that requires frequent disassembly. Flat head screws feature an anti-slip washer at the bottom to reduce the risk of loosening in vibrating environments. |
| Thread Self-Locking Optimization | For applications subject to vibration (such as motors and automotive components), some Machine Screw with Phillips Head sizes feature a fine thread design (pitch 0.5-1.0mm). Compared to coarse threads, fine threads have more engaging teeth, improving self-locking performance by over 35%, reducing vibration-induced screw loosening, and eliminating the need for additional anti-loosening washers, thereby reducing installation costs. |
| Precise Cross-Slot Positioning | CNC engraving is used to machine the cross slot, ensuring a coaxial error of ≤0.03mm between the slot center and the stainless steel pan head screws axis. This allows the screwdriver to quickly align with the slot during installation. This improves assembly efficiency by approximately 30%, especially in automated assembly scenarios (such as robotic screwdriving). This reduces equipment commissioning time. |
| Miniaturized Adaptive Design | Targeted at the miniaturization needs of electronic devices, we developed miniature M1-M2 cross-slot screws with a head diameter as small as 2mm and thread accuracy of 6g. Made of high-strength stainless steel, these stainless steel sheet metal screws provide sufficient fastening strength even in confined spaces, making them suitable for assembling precision electronic components such as smartphones and smart wearables. |
