• High-Quality Material: NZNSML M4 round head hex socket bolts are made of high-quality 304 stainless steel. They possess excellent corrosion and oxidation resistance without requiring any surface coating, making them suitable for damp, acidic, or alkaline environments. Their mechanical properties comply with the ISO 7380 standard, offering high strength, good toughness, and robust durability. Round head hex socket bolts are not easily deformed or rusted, ensuring a longer service life.
• Practical Set: NZNSML provides you with 40 sets of stainless steel round head hex socket nuts and bolts combinations. This includes 40pcs M4x25 mm round head hex socket bolts (thread diameter 4mm, length 25mm), paired with 40pcs nuts, 40pcs spring washers, and 40pcs flat washers. This complete set meets the batch assembly and maintenance needs of small and medium-sized equipment, effectively improving assembly efficiency.
• Hex Socket Drive: NZNSML stainless steel round head hex socket bolts feature a standard round head and hex socket drive structure. This ensures tight contact and high torque transmission efficiency, effectively preventing tool slippage and bolt head damage. The round head design sits flush naturally against the contact surface after installation, offering a neat appearance with no sharp edges, facilitating operation in confined or poorly visible spaces.
• Secure Anti-Loosening: Each NZNSML stainless steel round head hex socket button head bolts set is equipped with matching stainless steel nuts and spring washers. The dual anti-loosening mechanism, combining the mechanical locking of the nut and the continuous elastic preload of the spring washer, effectively resists loosening caused by equipment vibration or load fluctuations. This makes it particularly suitable for high-dynamic scenarios like motor bases and moving mechanisms.
• Wide Applicability: NZNSML stainless steel hex socket head cap screws set can be used not only for daily household scenarios such as fixing loose stool legs, reinforcing cabinets, installing bookshelf shelves, and repairing door/window hinges, but are also widely applicable in industrial assembly areas like instrument panels, chassis enclosures, and production line brackets. The stainless steel material is rust-resistant and easy to clean, suitable for use in damp environments like kitchens.
