Adhesive Coated Stainless Steel Screw
Adhesive Coated Stainless Steel Screw (alias: Adhesive Set Screw, Glue-Coated Machine Screw) is a high-precision fastener designed for vibration-resistant and anti-loosening applications, combining mechanical locking and chemical anti-loosening functions. Crafted from 304/201 premium stainless steel (containing chromium and nickel, anti-oxidation, acid-alkali resistant), the screw is 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.

Stainless Steel Positioning Sleeve
Stainless Steel Positioning Sleeve is a cylindrical precision fastener made of high-quality 304 stainless steel (containing 18% chromium and 8% nickel) with internal threads. Its core function is to precisely position and fix parts such as shafts, pins, and rods. By tightly mating with bolts via internal threads, it ensures parts maintain their correct position during assembly, effectively preventing loosening or displacement caused by vibration, impact, or repeated disassembly.

Blue-White Zinc Screw
Blue-White Zinc Screw (alias: Blue-White Zinc Set Screw, Color Zinc Machine Screw) is a fastener made of carbon steel (base material) with blue-white zinc (color zinc) electroplating on the surface. It is mainly used for part fixation and anti-loosening in machinery, furniture, building materials, and other fields. Its surface presents a uniform blue-white color, combining decorativeness and practicality: Anti-Corrosion: The blue-white zinc layer effectively isolates air, moisture, and mild corrosive media (e.g., water vapor in humid environments, weak acids/alkalis), preventing the carbon steel base from rusting. Suitable for humid or mildly corrosive environments; High Strength: The carbon steel material (common grades: 4.8, 8.8) maintains good mechanical properties (e.g., Grade 8.8 has a tensile strength ≥800MPa), suitable for occasions requiring a certain load-bearing capacity; Structural Design: Mostly adopts a hexagon socket drive design (compliant with ISO 4762 standard), convenient for tightening with wrenches, electric screwdrivers, and other tools; the thread is a metric standard (e.g., M8×1.25), with a regular tooth profile and small fit clearance (IT6 grade precision), ensuring reliable fixation.

Stainless Steel 304 Through Hole Round Nut
Stainless Steel 304 Through Hole Round Nut is a high-precision cylindrical fastener designed for fixing shaft parts. Its core structure includes: Through-hole design: A punch hole (diameter slightly larger than the shaft) allows shafts, pins, or bolts to pass through, eliminating the need for additional sleeves or washers, saving installation space; Hexagon socket drive: Compliant with ISO 4762 international standards, it is compatible with wrenches, electric screwdrivers, and other tools, ensuring convenient installation and high torque transmission; 304 stainless steel material: Containing 18% chromium and 8% nickel, it forms a dense passivation film, providing excellent corrosion resistance and oxidation resistance (capable of withstanding moisture, weak acids/alkalis, and salt spray), suitable for harsh environments such as food processing, medical equipment, and outdoor facilities. This product is primarily used to fix shafts, bearings, couplings, and small parts, preventing rotation or displacement. It is a core fastener in industries such as machine tools, precision machinery, and automobiles.
