Our Standard Fasteners (including Set Screws, nuts, etc.) strictly comply with international standards such as DIN, ANSI, and GB. Manufactured from high-strength carbon steel, stainless steel, and alloy materials, they offer excellent corrosion resistance, fatigue resistance, and high/low-temperature stability. Through precision stamping and heat treatment, we ensure consistent dimensions and reliable locking force. These fasteners are widely used in automotive manufacturing, machinery assembly, electronic devices, construction structures, and furniture installation. Whether in high-vibration environments or long-term outdoor exposure, they provide secure and durable connections. We also support non-standard customization, rapid prototyping, salt spray test reports, and batch traceability to help customers reduce inventory pressure and improve assembly efficiency.
Flat Point Set Screw (also known as Flat End Grub Screw) is a precision headless fastener engineered for secure positioning and fixation in mechanical, structural, and industrial applications. Crafted from 304 stainless steel, this screw features a hexagonal socket drive (for high-torque installation and anti-slip performance) and a flat end tip (ensuring flush mounting without protrusions, preventing damage to mating parts). Its corrosion-resistant, high-strength properties make it suitable for harsh environments, including food processing, marine use, and automotive manufacturing.
Read More Send InquiryThis product is a Hexagon Socket Cylinder End Set Screw (alias: Headless Screw, Machine Screw, Locking Screw), a high-precision fastener designed for secure part fixation and anti-loosening. It complies with German Standard DIN915 and Chinese National Standard GB79, with non-standard customization available for specific requirements. Crafted from Grade 4.8 high-quality carbon steel (carbon content: 0.15%-0.25%), it offers moderate strength (tensile strength ≥400MPa) and good toughness (elongation ≥22%), suitable for general industrial load-bearing applications. The surface is treated with blue-white zinc plating (plating thickness: 5-8μm), forming a dense anti-corrosion barrier to resist moisture and oxidation.

Crafted from 304/201 premium stainless steel (containing chromium and nickel, anti-oxidation, acid-alkali resistant), it features a small cylindrical flat-end structure (flat cylindrical end face without protrusions) and a hexagon socket drive (compliant with ISO 4762 standard, high-torque installation without slipping).
Read More Send InquiryExtra Sharp Point Set Screw (alias: Extra Sharp Machine Screw, Locking Screw, Headless Screw) is a high-precision, strong-positioning fastener designed for occasions requiring rapid positioning and prevention of part rotation. Crafted from 304/201 premium stainless steel (containing chromium and nickel, anti-oxidation, acid-alkali resistant), it features a sharp conical point (high-precision positioning, quick insertion into mounting holes) and a hexagon socket drive (compliant with ISO 4762 standard, high-torque installation without slipping).
Read More Send InquirySerrated 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.
Read More Send InquiryHex 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.
Read More Send InquiryHex 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.
