304PM round head Phillips stainless steel extended screw, pan head machine screw wholesale, M3/M4/M5/M6/M8

The core advantages of 304 stainless steel round head Phillips screws are "corrosion resistance in all scenarios, safety and scratch resistance, convenient disassembly and assembly, and wide adaptability."

1. 304 stainless steel material, featuring all-scenario corrosion and rust resistance with a core alloy ratio of 18% chromium + 8% nickel, forms a dense oxide film on the surface, which can withstand erosion from moisture, mild acids and alkalis, salt spray (non-coastal high concentration), daily cleaning agents, etc. It is resistant to rust and corrosion in kitchen, bathroom, balcony, outdoor rain shelter and other scenarios, with a service life 4-6 times that of carbon steel nickel-plated screws; there is no risk of plating peeling, no magnetism, environmentally friendly and non-toxic, suitable for food contact equipment (such as kitchen utensil fixation), children's products, medical equipment assembly assistance and other scenarios with material safety requirements.
2. With a round head structure, it is safe and scratch-resistant + offers gentle force application. The head is a semi-spherical shape, with edges that have undergone smooth chamfering treatment, eliminating sharp corners. Daily contact will not scratch clothing, skin, or precision internal components of equipment (such as home appliance wiring and plastic casings). Its safety is far superior to that of flat-head, countersunk-head, and other angular screws. The round head applies force more evenly, making it less likely to damage soft substrates such as wood and plastic due to excessive localized pressure during tightening. It is particularly suitable for furniture, children's products, frequently touched hardware accessories, and other scenarios.
3. With a cross slot drive, it is efficient and not easy to slip when disassembling and assembling. The cross slot is precisely positioned, with a high degree of fit with screwdrivers/electric screwdrivers, and stable torque transmission, making it less likely to "slip the batch" (damage due to slipping of the slot mouth) during disassembly and assembly. Whether it is factory batch assembly, on-site decoration and construction, or personal DIY maintenance, it can be quickly operated, and even in narrow spaces, novices can easily get started.
