Standard Nuts Products

The standard nuts product series includes hex nuts, flange nuts, lock nuts, round nuts, acorn nuts, and weld nuts in standard specifications, compatible with various bolts and studs. Manufactured from carbon steel, alloy steel, and stainless steel with strength grades covering Grade 4, 6, 8, 10, and 12 to meet fastening requirements under different load conditions. Surface finishes include plain, black oxide, zinc plating, Dacromet, and hot-dip galvanizing for excellent corrosion resistance. Products strictly comply with GB, DIN, ISO, ANSI, and other international standards, featuring precise dimensions and smooth thread go/no-go performance. Widely used in mechanical assembly, construction engineering, vehicle manufacturing, furniture production, and power facilities.

Serrated Flange Nut

Serrated Flange Nut is a high-performance fastener that adds radial serrated teeth on the underside of the flange based on the standard flange nut design. Its core structure consists of three parts: Hexagonal Head Body: A regular hexagonal design that fits various tightening tools (wrenches, sockets), ensuring convenient installation and high torque transmission efficiency; Circular Flange: A flat disk perpendicular to the nut axis, used to increase the contact area with the connected part, disperse preload, and protect thin-walled or soft materials; Serrated Teeth: Evenly distributed radial teeth on the flange underside that embed into the connected surface during tightening, significantly enhancing anti-loosening performance, especially suitable for high-vibration or dynamic load applications.

Hex Flange Nut

Hex Flange Nut is a standard fastener combining fixing function and pressure dispersion, widely used in scenarios requiring high-strength connection, protection of connected parts, or dispersion of preload. Its core structure consists of two parts: - Hexagonal Head Body: A regular hexagonal design that fits various tightening tools (wrenches, sockets), ensuring convenient installation and high torque transmission efficiency; - Circular Flange: A flat disk perpendicular to the nut axis, primarily used to increase the contact area with the connected part, disperse bolt preload, and avoid damaging thin-walled parts (e.g., metal plates, plastics) or soft materials.

Hex Hollow Nut

Hex Hollow Nut is a high-precision fastener designed for shaft parts, primarily used to fix shafts, pins, and other components to prevent rotation or axial movement. Crafted from 304 stainless steel (containing 18% chromium and 8% nickel), it offers excellent corrosion resistance (to atmospheric corrosion, organic acids, inorganic acids, and salt spray). The product features a hexagonal head + hollow cylinder + internal thread structure: Hexagonal Head: Complies with national standard GB/T 809, with precise across-flats dimensions, enabling easy tightening with universal tools (wrenches, sockets) and high installation efficiency; Hollow Cylinder: Uniform wall thickness (1.5-5mm) allows shaft parts to pass through, reducing weight and saving installation space without the need for additional sleeves or washers; Internal Thread: Regular thread profile (metric M series) ensures tight fit with bolts, providing reliable fixation.
