Products Description
Phillips head screws are common fasteners that are notable for having a cross-shaped drive slot in the head of the screw. This drive slot is adapted to a Phillips screwdriver, allowing tightening and loosening operations with the screwdriver. This design provides better torque transfer, reduces the risk of slipping, and is suitable for joining a variety of materials, such as wood, metal, and plastic.

Product Advantages
Consistent Slot Depth
We replace our molds regularly for each batch. If the slot is too shallow, the screwdriver slips as soon as it makes contact; if it's too deep, the bit wobbles. We ensure that the cross-slot symmetry is ≤0.05 mm and the depth tolerance is ±0.02 mm. When driven with a pneumatic screwdriver, it engages with a distinct "click" rather than a wobbly sensation.
No Debris Buildup on Threads
After the thread rolling process, we add a step of vibratory finishing or tumbling to remove microscopic burrs at the base of the threads. If you use these screws in an automatic screwdriver, you'll find the feed tube doesn't jam, because the thread profile of every screw is smooth and continuous.
Clear Hardness Grading
Grade 4.8 is Grade 4.8, and Grade 8.8 is Grade 8.8. We do not pass off lower-hardness screws as higher-hardness ones, nor do we use high-hardness screws in plastic (which would cause the plastic stud to split). If you're unsure which grade to use, tell us the material and torque requirements, and we'll provide recommendations.
Applications
In the construction sector, the threads of the Phillips head screws' shanks can securely join a variety of building materials together. For example, when fixing metal keels and wooden panels, by screwing in a Phillips head screw, its threads are able to grip the two different material components tightly. This operation ensures the safety of the building structure by resisting tensile, compressive and shear forces generated by wind loads, earthquakes and other external forces. In mechanical engineering, Phillips head screws are used to connect various parts of a machine, such as securing gears to a shaft or connecting a housing to an internal mechanical structure. Its threads can prevent parts from loosening due to vibration or inertial forces during machine operation, ensuring the normal operation of the machine.
Installation Notes
Use the correct Phillips screwdriver: Use a PH2 bit for PH2 screws. Do not force a PH1 bit, as it will slip.
Power Drill Torque Settings: For plastic parts, we recommend 0.3–0.8 N·m; for metal parts, 1.5–3.0 N·m. Test-tighten a few screws first to
find the torque that secures them firmly without damaging the slots.
For countersunk screws, pay attention to the countersink angle (90° or 82°). Inconsistent angles may cause the screw head to protrude above the surface or prevent the screw from being driven in.
