The source states 304 stainless steel, a material often chosen for fasteners where a stainless finish is preferred. The screw diameter is 3mm, the thread tolerance is 5g, and nominal lengths span 4mm to 20mm. The set also includes 230pcs nuts, making it a combined screw and nut kit rather than screws alone.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe screws are described as 304 stainless steel. This grade is commonly used for general fastening hardware, and it is relevant when a stainless steel fastener is wanted instead of a plain steel one. The round head shape sits above the fastened surface, while the hexagon socket drive allows tightening with a matching hex key. The nut quantity is given as 230pcs, and the thread specification is M3 with a 5g tolerance. No additional coatings, hardness values, or tensile strengths are provided in the source.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe screw diameter is 3mm, which corresponds to the M3 thread specification. Nominal lengths range from 4mm to 20mm, so the set can be used across small assembly points where different screw lengths are needed. Thread tolerance is stated as 5g. The option value is M3, and the set is supplied as a round head hexagon box. Only the measurements listed in the source are confirmed; no other dimensions, such as head diameter or head height, are given.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"M3 round head hexagon socket screws and 230pcs nuts in 304 stainless steel, 4-20mm lengths\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/2655\/2025-10-16\/original-image\/1620011024681.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis M3 screw and nut set is suited to machine thread fastening where the screw passes through a part and a nut is fitted on the other side. Because the set includes both screws and 230pcs nuts, it can be kept for jobs that need matching M3 hardware. The 4mm to 20mm nominal length range supports different material thicknesses, while the 304 stainless steel construction is relevant for general indoor fastening tasks. The source does not state specific applications, so the uses described here remain general.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eFor workshop, repair, or assembly tasks, having a range of M3 screws and matching nuts can reduce the need to source separate parts. The M3 thread specification and 5g tolerance are stated, and the 304 stainless steel material gives a known base material for the fasteners. The round head hexagon socket design allows the screw to be driven with a hexagon socket tool. No professional certifications or industry approvals are stated in the source, so this set should be selected on the supplied dimensions and material alone.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eAt home, this set can be useful for small fixes and hobby projects that require M3 machine thread screws and nuts.
