Standard OverviewJIS B1111 regulates cross-reinforced screws made of steel, stainless steel, and brass for general purposes, including large flat head screws.
Product FeaturesThe head is in the shape of a large flat head, which compared to the ordinary screw head, increases the contact area with the installed product, thereby increasing the friction coefficient, making the screw less likely to loosen. At the same time, the larger head also increases the aesthetics.。
Specifications and DimensionsCommon sizes include M3, M4, M5, and M6, with various lengths available. For example, Shanghai Huihao Stainless Steel Co., Ltd. offers stainless steel large flat head cross screws with 316 material, with specifications such as M3.16、M46、M48、M410、M412、M416、M418、M420、M425、M430、M435、M440、M56、M58、M510、M512、M516、M520、M525、M530、M535、M545、M550、M610、M612、M616、M618、M620、M622、M625、M630、M640、M645、M650th class1。
