Product Description
PRODUCT PARAMETER
Flange Nuts
Flange nuts feature a hexagonal body with an integrated circular flange at the base, eliminating the need for separate washers. This design expands the contact area, distributes clamping force evenly, and enhances anti-loosening performance in vibrating environments. Made of carbon steel (zinc-plated), stainless steel (304/316), or alloy steel, they come in grades like 4, 6, 8, and standards such as DIN 6923, ISO 4161. Sizes range from M5 to M30, with flange diameters 1.5–2× bolt diameter for optimal load distribution.
Applications include:
Automotive: Securing chassis parts and engine mounts (resists vibration).
Industrial Machinery: Fastening gearboxes and pumps in limited spaces.
Construction: Installing steel brackets and solar frames (stainless types for outdoors).
Marine/Chemical: Joining pipes in corrosive environments (corrosion-resistant materials).
Electronics: Fixing casings without surface damage.
