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).
Product Description
Stainless Steel Small Cylindrical Set Screw (alias: Small Cylindrical Flat-End Machine Screw, Locking Screw, Headless Screw) is a high-precision, corrosion-resistant fastener designed for secure part fixation and anti-loosening. 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).
Manufactured via precision thread processing technology (CNC lathe + thread rolling machine), the screw has regular thread profiles (pitch error ≤0.02mm) and tight fit (IT6 grade precision). It enables flush mounting (no protrusions) without damaging mating parts (e.g., shafts, gears), making it suitable for applications requiring high surface flatness and corrosion resistance (e.g., household appliances, outdoor facilities, medical equipment). The product effectively maintains the stability of assembled structures and prevents loosening caused by vibration or impact.

Product Feature
Premium Stainless Steel Material: Made of 304/201 stainless steel, it offers excellent corrosion resistance (e.g., against moisture, acidic/alkaline environments, salt spray), suitable for food, medical, and outdoor applications with high hygiene requirements (e.g., food processing machinery, outdoor play facilities).
Small Cylindrical Flat-End Design: The flat cylindrical end face does not damage mating parts (e.g., shafts, gears) during installation, and enables flush mounting (no protrusions) to maintain surface flatness. Ideal for products with high appearance requirements (e.g., household appliances, towel racks).
Precision Craftsmanship: Threads are processed with CNC thread rolling technology, ensuring uniform pitch (error ≤0.02mm) and consistent depth, tight fit (IT6 grade precision), and resistance to stripping, guaranteeing secure fixation (e.g., locks, electronic instruments).
Customization Service: The factory supports non-standard specification customization (e.g., adjusting nominal thread diameter, length, cylinder size) and provides free samples to meet special customer needs (e.g., irregular part fixation, high-precision requirements).
Wide Applicability: Covers multiple fields including security doors, locks, towel racks, outdoor facilities, electronic instruments, and household appliances, with strong adaptability (e.g., home decoration, industrial equipment, medical devices, communications).
