Flat Point Set Screw
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.

Carbon Steel Screw
This 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.

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.

Thread Locking Screws
Thread Locking Screws (alias: Glue-Coated Set Screws, Anaerobic Adhesive Screws) are stainless steel fasteners combining fixing function and anti-loosening performance, designed for high-precision scenarios requiring vibration resistance and secure fixation. Crafted from 304/316 premium stainless steel (containing chromium and nickel, anti-oxidation, acid-alkali resistant), the screws are treated with blue anaerobic adhesive (applied to the middle section of the thread). The adhesive fills the thread clearance, forming a "mechanical + chemical" dual-locking structure to effectively prevent loosening caused by vibration, impact, or repeated disassembly.
