DIN6921 Hexagon Flange Bolts Without Serrated Application Scenarios (Full English Table)

Application Field	Specific Application Scenarios	Relevant Standards	Strength Grade (Material)	Core Reasons for Selection
Household Use	1. Furniture assembly: Fixing of panel wardrobe door hinges, connection of plastic drawer slides 2. Home appliance installation: Fixing of rice cooker base anti-slip pads, splicing of humidifier shells	DIN 6921	Carbon Steel Grade 4.8, Stainless Steel A2-70	1. Smooth non-serrated flange surface prevents scratches on furniture boards and home appliance plastic shells; 2. Flange integrates washer function, eliminating the need for extra flat washers and simplifying home DIY installation.
Construction	1. Indoor decoration: Fixing of light hangers for gypsum board ceilings, splicing of wooden decorative lines on walls 2. Light components: Installation of aluminum alloy balcony shelves, connection of bathroom vanities to walls	DIN 6921	Carbon Steel Grade 5.6, Stainless Steel A4-80	1. Non-serrated design avoids damaging gypsum boards and wooden decorative layers, ensuring the integrity of building decoration appearance; 2. Flange increases contact area to disperse pressure, preventing light components from indentating wall substrates
Industrial Equipment	1. Light machinery: Fixing of plastic-shell motor guards, sealed connection of small water pump end caps 2. Storage equipment: Connection of light plastic shelf boards to columns	DIN 6921	Carbon Steel Grade 8.8, Stainless Steel A2-70	1. Non-serrated flange fits thin-walled plastic/metal shells, avoiding scratches or deformation during installation;
Electronic & Electrical	1. Instrument enclosures: Splicing of plastic oscilloscope enclosures, fixing of multimeter battery compartment covers 2. Communication devices: Connection of router plastic casings to bases, fixing of small switch panels	DIN 6921	Stainless Steel A2-70, Carbon Steel Grade 5.6	1. Non-serrated design avoids damaging precision plastic shells of electronic devices, ensuring product appearance consistency; 2. Small sizes fit narrow installation spaces of electronic devices, and the flange prevents bolts from sinking into the shell.
