At the same time, they are strong and tough enough to withstand certain tensile force, pressure and shear force, ensuring a solid and reliable connection in all kinds of DIY projects and providing long-lasting support for your works.
Precise size: M3 and M4 standard sizes with clear, regular threads, even pitch, and tight fit with nuts and other connectors to ensure precise installation and solid connection. The length starts from 4mm and increases in 5mm or 10mm gradient up to 180mm, abundant choices to meet the fastening needs of different thicknesses of materials, you can easily select the right length according to the actual project, avoiding installation problems or material waste caused by improper sizes, and making your DIY operation more convenient.
Flat head Phillips design: The flat head design makes the head of the screw flush with or slightly below the surface of the workpiece after installation, which is not only aesthetically pleasing and generous, but also effectively avoids scratches, collisions and other potential safety hazards caused by the protruding head of the screws, and at the same time reduces the occupation of space, which is suitable for all kinds of DIY projects that have requirements on appearance and space. Phillips slot design facilitates you to use common Phillips screwdriver for quick and convenient operation, easy to apply force, whether it is manually tightened or used with an electric screwdriver, it can easily cope with a variety of installation and dismantling tasks, which greatly improves your work efficiency.
EXCELLENT MANUFACTURING CRAFT: Each machine screw undergoes a strict manufacturing process and quality inspection process, with a smooth and burr-free surface to ensure that no damage is caused to the material to be fixed in the process of screwing in and screwing out, and at the same time ensure the smoothness and comfort of operation. The advanced production process ensures the consistency of the screw's dimensional accuracy and mechanical properties, which makes you feel more assured and reliable in the process of using it, and provides stable quality assurance for your DIY projects.

Home Decoration and Small Furniture Making: M3 and M4 screws can be used to connect various parts when making small wooden bookshelves, photo frames, decorative boxes, and other home furnishings. For example, M3 screws can fix the back and sides of photo frames to make them more stable, while M4 screws are suitable for connecting the shelves and side panels of bookshelves to ensure that the shelves can withstand a certain weight of books. The stainless steel exterior also matches a variety of home décor styles, adding a touch of sophistication and durability.
Electrical equipment repair and assembly: when repairing computer mainframes, small electrical enclosures, lamps and other equipment, these machine screws often play an important role.M3 screws can be used to fix the circuit boards inside the appliance, heat sinks and other parts, M4 screws can be used to connect the shell and larger bracket parts. Their good electrical conductivity and corrosion resistance can ensure the normal operation and safety of electrical equipment, and at the same time, it is convenient for you to carry out disassembly and maintenance, which saves your time and energy.
Outdoor facilities construction and gardening tools production: when building outdoor drying racks, small flower racks, bird cages and other facilities, the corrosion resistance of 304 stainless steel flat head Phillips machine screws is particularly important. They can resist the erosion of rain, sunlight, dew and other natural elements to ensure the stability and safety of the facilities. In addition, you can also use these screws to make gardening tools, such as shovels, rakes handle connection part, make it more durable and meet the needs of outdoor use.
Handmade creative works and model building: For handmade enthusiasts to make all kinds of creative works, such as metal crafts, wooden models, robot models, etc., the screws of M3 and M4 provide flexible and various connection methods. You can choose different lengths of screws to fix various parts according to the design requirements of your works and realize unique creative effects. In model building, they can simulate the connection of real structures, making the model more realistic and stable, so that your creativity can be perfectly presented.
4. Product use instructions
Choose the right specification and quantity: Before starting your DIY project, carefully choose the right specification of machine screws according to the type and thickness of the material to be fastened and the force it needs to withstand. Refer to the specification table and suggested usage scenarios provided by us to ensure that the diameter and length of the screws can meet your fastening needs. At the same time, according to the complexity of the project and the number of connection points, reasonably estimate the number of screws required to avoid affecting the project progress due to insufficient screws or waste due to excessive purchase.
Preparation tools: You need to prepare a suitable size Phillips screwdriver and make sure that the screwdriver's bit closely matches the screw's Phillips slot to avoid damaging the screw slot or the screwdriver's bit during the installation process. For some larger-scale projects or the need for frequent installation and removal of screws, it is recommended to prepare an electric Phillips screwdriver, which can improve the efficiency of the work, but pay attention to the control of the tightening force to prevent over-tightening.
Installation steps:
Align the screws with the part to be fixed, and gently rotate the screwdriver so that the screws initially enter the threaded holes. Take care to keep the screws perpendicular to the surface to be fixed to avoid tilting the installation resulting in thread damage or poor connection. If installing on a harder material, you may wish to first pre-drill a pilot hole using a drill bit slightly smaller than the screw diameter, which will make the screw easier to screw into while reducing the risk of cracking the material.
Turn the screwdriver slowly and gradually tighten the screw. During tightening, apply force evenly, rotate the screwdriver in a clockwise direction, and do not rotate at too large an angle each time to avoid uneven force on the screw. For some connections that require high tightening force, such as the load-bearing parts of furniture or key connection points of outdoor facilities, the screws can be tightened gradually over several times, and the flatness and stability of the connection should be checked after each tightening to ensure that the screws are evenly loaded and fit tightly with the material to be fixed.
Determine the degree of tightening of the screws according to the actual situation. Generally speaking, in the metal material tightened to the screw head and the workpiece surface close fit, and then properly apply a little extra force can be; for wood and other softer materials, to avoid over-tightening lead to material rupture, in order to screws can be securely fixed and the material is not obvious deformation is appropriate. In some projects that require high precision, such as electronic equipment maintenance or precision model building, you can use a torque wrench to tighten according to the specified torque value to ensure that the tightening force of each screw is the same, to ensure the normal operation of the equipment and performance stability.
